It was Just a Bag of Candy, but Now It’s a Lung – Don’t Be Afraid to Improvise When Teaching Physiology

Many of us have been teaching the same course or the same topic in a team-taught course for many years.  I have been teaching the undergraduate Anatomy and Physiology-II (AP-II) course at a community college for four years.  People often ask, “Doesn’t it get old?  Don’t you get bored, teaching the same topic?”  Without hesitation, I answer, “No.” Why?  First, on-going research continually brings new details and insight to nearly every aspect of cell and integrative physiology.  You’re always learning to keep up with the field and modifying lectures to incorporate new concepts.  Second, you truly want your students to learn and enjoy learning and continually seek out ways to teach more effectively.  You try new approaches to improve student learning.  However, the third reason is truly why teaching physiology will never get old or dull.  No two students and no two classes are alike; individual and collective personalities, career goals, academic backgrounds and preparedness, and learning curves vary from class to class.  About half my students have not taken the general biology or chemistry courses typically required for AP-I or AP-II (these are not required by the college).  The unique combination of characteristics in each group of students means that on any given day I will need to create a new makeshift model or a new analogy for a physiological mechanism or structure-function relationship to help students learn.  Thus, even if all physiological research came to complete fruition, the teaching of physiology would still be challenging, interesting, and entertaining.  Many of my peers share this perspective on teaching physiology.

Irrespective of one’s mastery of integrative physiology, as teachers we must be ready and willing to think creatively on our feet to answer questions or clarify points of confusion.  A common mistake in teaching is to interpret the lack of questions to mean our students have mastered the concept we just explained, such as the oxygen-hemoglobin dissociation curve.  Despite the amazing color-coding of green for pH 7.35, red for pH 7.0 and blue for pH 7.5 and perfectly spaced lines drawn on that PowerPoint slide, your Ms./Mr. Congeniality level of enthusiasm, and sincerest intentions – you lost them at “The relationship of oxygen saturation of hemoglobin to the partial pressure of oxygen is curvilinear.”  You know you lost them.  You can see it in their faces.  The facial expression varies: a forehead so furrowed the left and right eyebrows nearly touch, the cringing-in-pain look, the blank almost flat stare, or my favorite – the bug-eyed look of shock.  Unfortunately, it will not always be obvious.  Thus, it is essential we make an effort to become familiar with the class as a group and as individuals, no matter how large the class.  Being familiar with their baseline demeanor and sense of humor is a good start.  (I have students complete ‘Tell Me About Yourself’ cards on the first day of class; these help me a great deal.)  During lecture, we make continual and deliberate eye contact with the students and read their faces as we lecture and talk to them, rather than at them.  In lab we work with and talk to each group of students and even eavesdrop as a means to assess learning.  Time in class or lab is limited, which tempts us to overlook looks of confusion and move on to the next point.  However, when students do not accurately and confidently understand a fundamental concept, they may have even greater difficulty understanding more integrated and complicated mechanisms.  You must recognize non-verbal, as well as subtle verbal cues that students are not following your logic or explanation.  In that immediate moment you must develop and deliver an alternative explanation.  Improvise.

As per Merriam-Webster, to improvise is to compose, recite, play, or sing extemporaneously; to make, invent, or arrange offhand; to fabricate out of what is conveniently on hand.  What do you have on hand right now to create or develop a new explanation or analogy?  Work with what you have within the confines of the classroom.  These resources can be items within arm’s reach, anything you can see or refer to in the classroom.  You can also use stories or anecdotes from your own life.  Reference a TV commercial, TV show, movie, song, or cartoon character that is familiar to both you and your students.  Food, sports, and monetary issues can be great sources for ideas.  I cook and sew, which gives me additional ideas and skills.  Play to your strengths.  Some people are the MacGyvers of teaching; improvisation seems to be a natural born gift.  However, we all have the basic ability to improvise.  You know your topic; you are the expert in the room.  Tap into your creativity and imagination; let your students see your goofy side.  Also, as you improvise and implement familiar, everyday things to model or explain physiological or structure-function relationships you teach your students to think outside the box.  Students learn by example.  My own undergraduate and graduate professors improvised frequently.  My PhD and post-doc advisors were comparative physiologists – true masters of improvised instrumentation.

Improvise now, and improve later.  Some of my improvised explanations and demonstrations have worked; some have fallen flat.  In some cases I have taken the initial improvised teaching tool and improved the prototype and now regularly use the demonstration to teach that physiological concept.  Here are three examples of improvisational analogies I have used for the anatomy of circular folds in the intestine, the opening and closing of valves in the heart, and the role of alveoli in pulmonary gas exchange.  Disclaimer:  These are not perfect analogies and I welcome comments.

Surface area in the small intestine.  Students understand that the surface area of a large flat lab table is greater than the surface area of a flat sheet of notebook paper.  A sheet of paper can be rolled into a tube, and students understand that the surface area of the ‘lumen’ is equal to the surface area of the paper.  In AP-I, students learned that microvilli increase the surface area of the plasma membrane at the apical pole of an epithelial cell, and many teachers use the ‘shag carpet’ analogy for microvilli.  Similarly, they understood how villi increase surface area of the intestinal lumen.  However, some students did not quite understand or cannot envision the structure of circular folds.  As luck would have it, I was wearing that style of knit shirt with extra-long sleeves that extend just to your fingertips.  I fully extended the sleeve and began to explain. “My sleeve is the small intestine – a tube with a flat-surface lumen (my arm is in the lumen) – no circular folds.  This tube is 28 inches long and about 8 inches around.  As I push up my sleeves as far as I can, and the fabric bunches up.  These messy folds that form are like circular folds.  And, now this 6 inch tube with all these circular folds has the same surface area as the 28-inch plain tube.”  (I sew; I know the length of my own arm and am great at eyeballing measurements.)

Heart valves open and close as dictated by the pressure difference across the valve.  This is integral to ventricular filling, ejection of blood into the lung and aorta, and the effect of afterload.  Heart valves are one-way valves.  A few students heard ‘pressure difference’ and were lost.  Other students had trouble understanding how stroke volume would decrease with an increase in afterload.  What can I use in the room?  There’s a big door to the lab, and it has a window.  It opens in one direction – out, because of the doorframe, hinges and door closure mechanism; it only opens, if you push hard enough.  I ran over to the door.  “The lab door is a heart valve.  It’s the mitral valve, the lab is the atrium, and the hallway is the ventricle.  The door only opens into the hall – the mitral valve only opens into the ventricle.  When it closes, it stops once it sits in the frame.”  I asked a student about my size to go outside the room, and push against the door closed – but let me open it; she could see and hear me through the window.  “As long as I push with greater force than she applies to keep it shut, the door or valve will open.”  The student played along and made it challenging, but let me open the door.  ‘Blood flows from the atrium into the ventricle, as long as the valve is open.  But, as soon as the pressure in the ventricle is greater than the pressure in the atrium the valve closes.”  The student forcefully pushed the door shut.  They got it!  Now, afterload …?  Back to the lab door.  “Now the lab door is the aortic valve, the lab is the left ventricle, and the hall is the aorta.  This valve will open and stay open as long as the pressure in the ventricle is greater than the pressure in the aorta.  The longer the valve is open, the greater the volume of blood ejected from the ventricle.  The volume of blood ejected from the ventricle in one beat is the stroke volume.  The pressure that opposes the opening of the aortic valve is afterload.  What happens with afterload?”  I then asked the tallest, strongest student in class to play the role of Afterload; he too got into the role.  “Afterload has now increased!  The pressure that opposes the opening of the valve has increased.  Will I or won’t I have to push harder to open the door – now that afterload has increased?”  The student is very strong; I can barely push the door open.  “I not only have to push harder, but I can’t keep the door or valve open for very long.  Look.  Even though the ventricle pressure is greater, the valve is open for a shorter period – so less blood is ejected and stroke volume decreases.”

Alveoli increase the surface area for gas exchange.  Students see the lungs as 2 large sacs, and the surface area available for gas exchange between air and blood is simply the inner lining of each sac.  However, each lung is made of millions of tiny air sacs or alveoli into which air flows.  How this anatomical arrangement greatly increases surface area for gas exchange is not intuitively obvious.  The overall size of the lung does not increase, so why would the surface area increase?  As luck would have it, it was Halloween.  I had brought a big bonus bag of individually wrapped bite-size candies to class.  “One lung is like this bag.  If we cut open the bag and measure the sheet of plastic, it would be about 18 inches by 12 inches or 216 square inches.  But if we completely fill it with candy, it might hold at least 150 pieces of candy.”  I quickly unwrapped one piece of candy, held up the wrapper, and estimated a single wrapper was 4 square inches.  “If we fill one bag with 150 pieces of candy, we then have 600 square inches of surface area.  Which would provide greater area for gas exchange: one big lung or millions of alveoli?”  I revised this particular improvised explanation using scissors, a ruler and two 11-oz bags of Hershey’s® kisses.  I carefully opened both bags and transferred kisses from one bag to the other, until it was completely full, i.e., 112 kisses, and taped it shut.  I then fully opened up the other bag; it was 10 inches x 8 inches or 80 square inches.  An individual kiss wrapper is 4 square inches; all 112 individual wrappers are 448 square inches.

My improvised analogies are not perfect, but they have served as great teaching tools.  If you can improve upon these, please do.  Share any suggestions you have and lastly, share your improvised explanations and analogies.  Thanks.

Mentoring Mindsets and Student Success

There are numerous studies showing that STEM persistence rates are poor (especially amongst under-represented minority, first-generation, and female students) (1-2). It is also fairly broadly accepted that introductory science and math courses act as a primary barrier to this persistence, with their large class size. There is extensive evidence that first-year seminar courses help improve student outcomes and success, and many of our institutions offer those kinds of opportunities for students (3). Part of the purpose of these courses is to help students develop the skills that they need to succeed in college while also cultivating their sense of community at the university.  In my teaching career, I have primarily been involved in courses taken by first-year college students, including mentoring others while they teach first-year courses (4). To help starting to build that sense of community and express the importance of building those college success skills, I like to tell them about how I ended up standing in front of them as Dr. Trimby.

I wasn’t interested in Biology as a field when I started college. I was going to be an Aerospace Engineer and design spaceships or jets, and I went to a very good school with a very good program for doing exactly this. But, college didn’t get off to the best start for me, I wasn’t motivated and didn’t know how to be a successful college student, so my second year of college found me now at my local community college (Joliet Junior College) taking some gen ed courses and trying to figure out what next. I happened to take a Human Genetics course taught by Dr. Polly Lavery. At the time, I didn’t know anything about Genetics or have a particular interest, I just needed the Natural Science credit. Dr. Lavery’s course was active and engaged, and even though it didn’t have a lab associated with it we transformed some E. coli with a plasmid containing GFP and got to see it glow in the dark (which, when it happened almost 20 years ago was pretty freaking cool!). This was done in conjunction with our discussions of Alba the glow-in-the-dark rabbit (5). The course hooked me! I was going to study gene therapy and cure cancer! After that semester, I transferred to Northern Illinois University and changed my major to Biology.

So, why do I bring this up here? When I have this conversation with my undergraduate students, my goal is to remind them that there will be bumps in the road. When we mentor our students, whether it be advisees or students in our classes, it is important to remind them that failure happens. What matters is what you do when things do go sideways. That is really scary for students. Many of our science majors have been extremely successful in the lead up to college, and may have never really failed or even been challenged. What can we do to help our students with this?

First of all, we can build a framework into our courses that supports and encourages students to still strive to improve even if they don’t do well on the first exam. This can include things like having exam wrappers (6)  and/or reflective writing assignments that can help students assess their learning process and make plans for future assessments. Helping students develop self-regulated learning strategies will have impacts that semester (7) and likely beyond. In order for students to persevere in the face of this adversity (exhibit grit), there has to be some sort of hope for the future – i.e. there needs to be a reasonable chance for a student to still have a positive outcome in the course. (8) This can include having a lower-stakes exam early in the semester to act as a learning opportunity, or a course grading scale that encourages and rewards improvement over the length of the semester.

Secondly, we can help them to build a growth mindset (9), where challenges are looked forward to and not knowing something or not doing well does not chip away at someone’s self-worth. Unfortunately, you cannot just tell someone that they should have a growth mindset, but there are ways of thinking that can be encouraged in students (10).

Something that is closely tied to having a growth mindset is opening yourself up to new experiences and the potential for failure. In other words being vulnerable (11). Many of us (and our students) choose courses and experiences that we know that we can succeed at, and have little chance of failure. This has the side effect of limiting our experiences. Being vulnerable, and opening up to new experiences is something important to remind students of. This leads to the next goal of reminding students that one of the purposes of college is to gain a broad set of experiences and that for many of us, that will ultimately shape what we want to do, so it is okay if the plan changes – but that requires exploration.

As an educator who was primarily trained in discipline-specific content addressing some of these changes to teaching can be daunting. Fortunately there are many resources available out there. Some of them I cited previously, but additional valuable resources that have been helpful to me include the following:

  • Teaching and Learning STEM: A Practical Guide. Felder & Brent Eds.
    • Covers a lot of material, including more information of exam wrappers and other methods for developing metacognitive and self-directed learning skills.
  • Cheating Lessons: Learning from Academic Dishonesty by Lang
    • Covers a lot relating to student motivation and approaches that can encourage students to take a more intrinsically motivated attitude about their learning.
  • Rising to the Challenge: Examining the Effects of a Growth Mindset – STIRS Student Case Study by Meyers (https://www.aacu.org/stirs/casestudies/meyers)
    • A case study on growth mindset that also asks students to analyze data and design experiments, which can allow it to address additional course goals.

Creating Unique Learning Opportunities by Integrating Adaptive Learning Courseware into Supplemental Instruction Sessions

Teaching a large (nearly 400 students), introductory survey course in human anatomy and physiology is a lot like trying to hit a constantly moving target. Once you work out a solution or better path for one issue, a new one takes its place. You could also imagine a roulette wheel with the following slots: student-faculty ratios, student preparation, increasing enrollments, finite resources, limited dissection specimen availability (e.g., cats), textbook prices, online homework, assessment, adaptive courseware, core competencies, learning outcomes, engagement, supplemental instruction, prerequisites, DFW rates, teaching assistants, Dunning Kruger effect, open educational resources, GroupMe, student motivation, encouraging good study habits, core concepts, aging equipment … and the list goes on.

If the ball lands on your slot, are you a winner or loser?

Before getting ahead of myself, I need to provide an overview of A&P at the University of Mississippi. Fall semesters start with 390 students enrolled in A&P I within one lecture section, 13 lab sections at 30 students each, anywhere from 10-13 undergraduate teaching assistants, 2 supplemental instruction (SI) leaders, and at least six, one-hour SI sessions each week. The unusual class size and number of lab sections is the result of maxing out lecture auditorium as well as lab classroom capacities. I am typically the only instructor during the fall (A&P I) and spring (A&P II) terms, while a colleague teaches during the summer terms. The two courses are at the sophomore-level and can be used to fulfill general education requirements. There are no prerequisites for A&P I, but students must earn a C or better in A&P I to move on to A&P II. Approximately one-third of the students are allied health (e.g., pre-nursing) and nutrition majors, one-third are exercise science majors, and the remaining one-third of students could be majoring in anything from traditional sciences (e.g., Biology, Chemistry, etc.) to mathematics or art.

The university supports a Supplemental Instruction program through the Center for Excellence in Teaching and Learning (https://cetl.olemiss.edu/supplemental-instruction/). The SI program provides an extra boost for students in historically demanding courses such as freshman biology, chemistry, physics, accounting, etc. SI leaders have successfully passed the courses with a grade of B or better, have been recommended to the program by their professors, agree to attend all lectures for the courses in which they will be an SI leader, and offer three weekly, one-hour guided study sessions that are free to all students enrolled in the course. SI leaders undergo training through Center for Excellence in Teaching and Learning and meet weekly with the course professor. Students who regularly attend SI sessions perform one-letter grade higher than students who do not attend SI sessions.

It can be as easy for an instructor to be overwhelmed by the teaching side of A&P as it is for the student to be overwhelmed by the learning side! I know that a major key to student success in anatomy and physiology courses is consistent, mental retrieval practice across multiple formats (e.g., lectures, labs, diagrams, models, dissection specimens, etc.). The more a student practices retrieving and using straightforward information, albeit a lot of it, the more likely a student will develop consistent, correct use. Self-discipline is required to learn that there are multiple examples, rather than one, of “normal” anatomy and physiology. However, few students know what disciplined study means beyond reading the book and going over their notes a few times.

To provide a model for disciplined study that can be used and implemented by all students, I developed weekly study plans for A&P I and II. These study plans list a variety of required as well as optional activities and assignments, many of which are completed using our online courseware (Pearson’s Mastering A&P) and include space for students to write completion dates. If students complete each task, they would spend approximately 10 out-of-class hours in focused, manageable activities such as:

  • Completion of active learning worksheets that correlate to learning outcomes and can be used as flashcards.
  • Practice assignments that can be taken multiple times in preparation for lecture exams and lab practicals.
  • Self-study using the virtual cadaver, photographic atlas of anatomical models, interactive animations of physiological processes, virtual lab experiments, and dissection videos.
  • Regular graded assignments aligned with course learning outcomes.

Weekly study plans are also useful during office visits with students. I can easily assess student progress and identify changes for immediate and long-term improvement. An advantage of using online courseware to support course objectives is the ability to link various elements of the courses (e.g., lecture, lab, SI sessions, online homework, group study, and self-study) with a consistent platform.

All of this sounds like a great sequence of courses, doesn’t it? Yet, the target has kept moving and the roulette wheel has kept spinning. Imagine for the story within this blog that the roulette ball has landed on “using adaptive courseware to improve supplemental instruction.”

In 2016 the University of Mississippi was one of eight universities chosen by the Bill and Melinda Gates Foundation with support of the Association for Public and Land-Grant Universities to increase the use of adaptive courseware in historically demanding general education courses. Thus, began the university’s PLATO (Personalized Learning & Adaptive Teaching Opportunities) Program (https://plato.olemiss.edu/). The PLATO grant provides support for instructors to effectively incorporate adaptive courseware into their courses and personalize learning for all affected students. Administrators of the grant were particularly supportive of instructors who could use adaptive courseware to support the SI sessions. This challenge was my personal roulette ball.

I decided to use diagnostic results from Mastering A&P graded homework assignments to prepare for weekly meetings with SI leaders. Diagnostic data on percent of University of Mississippi students correctly answering each question as well as percent of UM students answering incorrect options are compared to the global performance of all Mastering A&P users. For each question incorrectly answered by more than 50% of the students, I write a short (4-6 sentences) explanation of where students are making errors in expressing or using their knowledge and how to prevent similar errors in the future. I then searched for active learning activities and teaching tips associated with the challenging questions from the LifeSciTRC (https://www.lifescitrc.org/) and Human Anatomy and Physiology Society (HAPS; https://www.hapsweb.org/) websites. I specifically search for active learning exercises that can be conducted in a small, group setting using widely available classroom resources (e.g., white board, sticky notes, the students, etc.).

By using online courseware diagnostics, selecting focused learning activities, and communicating regularly with SI leaders, I was able to create value and unique learning opportunities for each student. The SI session format has been extremely well-received by the students and they immediately see the purpose in the study session experience. The best part is that it takes me only 30-40 minutes each week to write up explanations for the diagnostics and find the best learning activities.

I would say that we are all winners with this spin of the wheel.

How to motivate students to come prepared for class?

The flipped classroom is a teaching method where the first exposure to the subject occurs in an individual learning space and time and the application of content is practiced in an interactive guided group space. Freeing up class time by shifting traditional lecture outside of class allows the instructor more time for student-centered activities and formative assessments which are beneficial to students. The flipped teaching model has been shown to benefit students as it allows self-pacing, encourages students to become independent learners, and assists them to remain engaged in the classroom. In addition, students can access content anytime and from anywhere. Furthermore, collaborative learning and peer tutoring can be integrated due to freed-up class time with this student-centered approach. Given these benefits, the flipped teaching method has been shown to improve student performance compared to traditional lecture-based teaching. Compared to the flipped classroom, the traditional didactic lecture is considered a passive type of delivery where students may be hesitant to ask questions and may omit key points while trying to write or type notes.

There are two key components in the flipped teaching model: pre-class preparation by students and in-class student-centered activities. Both steps involve formative assessments to hold students accountable. The importance of the pre-class assessment is mainly to encourage students to complete their assignments and therefore, they are better prepared for the in-class application of knowledge. In-class activities involve application of knowledge in a collaborative space with the guidance of the instructor. Although the flipped teaching method is highly structured, students still come to class unprepared.

Retrieval practice is yet another powerful learning tool where learners are expected to recall information after being exposed to the content. Recalling information from memory strengthens information and forgetting is less likely to occur. Retrieval of information strengthens skills through long-term meaningful learning. Repeated retrieval through exercises involving inquiry of information is shown to improve learning.

The use of retrieval strategy in pre-class assessments is expected to increase the chance of students completing their pre-class assignment, which is often a challenge. Students attending class without having any exposure to the pre-class assignment in the flipped classroom will drastically affect their performance in the classroom. In my flipped classroom, a quiz consisting of lower level of Bloom’s taxonomy questions is given over the pre-class assignment where the students are not expected to utilize any resources or notes but to answer questions from their own knowledge. Once this exercise is completed, a review of the quiz and the active learning portion of the class occurs. I use a modified team-based learning activity where the groups begin answering higher order application questions. Again, no resources are accessible during this activity to promote their preparation beforehand. Since it is a group activity, if one student is not prepared, other students may fill this gap. The group typically engages every student and there is a rich conversation of the topic being discussed in class. The classroom becomes a perfect place for collaborative learning and peer tutoring. For rapid feedback to the students, the group answers to application questions are discussed with the instructor prior to the end of the class session.

Student preparation has improved since the incorporation of the flipped teaching model along with retrieval exercises in my teaching, but there are always some students who are not motivated to come prepared to class. It is possible that there are other constraints students may have that we will not be able to fix but will continue to be searching for and developing newer strategies for helping these students maximize their learning.

My First Run at Teaching an Integrated Physiology Course: Lessons Learned

One of the primary factors that attracted me to my current position, a tenure-track Assistant Professor of Biology at a small teaching-intensive liberal arts college, was the fact that my new department gave me the freedom to update and, in the end, completely overhaul the existing Anatomy and Physiology (A&P) curriculum. This position allowed great academic freedom, especially to a new professor, and department support for trying new teaching strategies and activities was, and still is, very high. So as a new entrant into the field of physiology education, and as someone who is interested in pedagogical research, this opportunity and level of freedom excited me.

My predecessor, while a fantastic educator, had built the year-long A&P sequence in the traditional form of one to two weeks on a specific topic (e.g. histology, the skeletal system, or the respiratory system) and an exam every so often that combined the previously covered topics. Both the topics covered and the exams could very much stand on their own, and were more like separate units. This course design was exactly the way I took the A&P course, longer ago than I care to admit, although at a different institution. In fact, most of my college courses were taught this way. And while that may be appropriate for some fields, the more I was reading and learning about teaching A&P the more I was starting to convince myself that I wanted teach A&P in an integrated fashion as soon as I got the chance.

So here I was, the bright-eyed and bushy-tailed newly minted Assistant Professor of Biology, with the academic freedom to teach A&P in the best way that I saw fit. One important thing to note: this course sequence (A&P I and II) is an upper-division junior and senior level course at my college, and class sizes are very small (20-24 students) allowing for maximum time for interaction, questions, and instructor guidance both in lecture and lab. (That latter point is key, but we’ll talk more about that in a minute.)

I entered the 2017-2018 academic year with a brand-new, shiny, exciting, and most importantly, integrated A&P course plan and a lot of enthusiasm. Along the way I took meticulous notes on what worked, what didn’t work, and the areas that needed improvement. Now in the 2018-2019 academic year I’m teaching this integrated course sequence for the second time, all while taking those same meticulous notes and comparing student feedback. Below I’ve compiled what I deem (so far) to be some of the most important lessons that I learned along the way:

 1) Use an integrative textbook.

This I was fortunate to do from the start. While this is an A&P course (not just P), I decided to use Physiology: An Integrated Approach by Dee U. Silverthorn as my primary text. Not only is the book already designed to be used in an integrative fashion, but there is ample introductory material which can be used to remind students of previous course material that they need to know (see lesson #2 below) and there are entire chapters dedicated to the integration of multiple systems (e.g. exercise). The assessment questions in the text are also well organized and progressive in nature and can be assigned as homework for practice or pre-reading assignments. Anatomy information, such as the specifics of the skeletal system and joints, muscles, histology, etc., was supplemented through the use of models and other reference material in hands-on lab activities.

2) Start building and assessing students’ A&P knowledge from the ground up, and build incrementally.

There are two important parts to this lesson: A) previous course knowledge that is applicable to this upper-division A&P course, and B) the new A&P material itself.

In my initial run of the course I made the mistake of starting out at a bit too advanced of a content level. I assumed more knowledge was retained from previous courses by the students than actually was. I learned very quickly that I needed to take a step back, but not too far. Instead of re-teaching introductory chemistry, biology, and physics, I took the opportunity to remind them of the relevant key principles (e.g. law of mass action) and then pointed them to pages in the text or provide additional material where they could review.

I applied this same philosophy as we progressed through new material. Lower-order Bloom’s principles should be assessed and mastered first, before progressing to the higher-order skills for each new section. In my second iteration of the course I implemented low-stakes (completion-based grade) homework assignments to be completed before the class or lab period, which were aimed to get a head-start on the lower-order skills. Then in class we reviewed these questions within the lecture or lab and added on with more advanced questions and/or activities. This format of pre-class homework was very well received by the students, and even though it is more work for them, they said that it encouraged them to keep up with the reading and stay-on track in the class. As the class progressed, I added in more advanced homework problems that integrated material from previous chapters. Obviously, if you are going to teach in an integrated fashion then you will need to assess the students in the same way, but a slow-build up to that level and ample low-stakes practice is key.

3) Create a detailed course outline, and then be prepared to change it.

This lesson holds true for just about any course, but I found it especially true for an integrated A&P course. As an instructor, not only did I need to be well versed in A&P, but I also needed to see the big picture and connect concepts and ideas both during the initial course construction and as the course progressed. I went into the course with an idea of what I wanted (and needed) to cover and during the course students helped guide what topics they struggled with and/or what they wanted to learn more about. So while still sticking to covering the basics of a course, I was still able to dive a bit deeper into other topics (such as exercise) per student interest. This also helped boost motivation for student learning when they feel they have some agency in the material.

Another aspect of the lesson is the addition of what I call “flex days”. Students will find this style of teaching and learning challenging and some will need more time and practice with the material. I found it very helpful to add in a “flex day” within each unit where no new material was covered, but instead time was dedicated to answering questions and additional practice with the concepts. If a full class day can’t be dedicated, even 30 minutes can be put to great use and the students really appreciate the extra time and practice.

 

4) Constantly remind your students of the new course format.

Students will want to revert back to what they are comfortable with and what has worked for them in the past. They will forget that information needs to be retained and applied later in the course. I found that I needed to constantly remind students that their “cram and forget” method will not serve them well in this course. But, simply telling them is not enough, so I allowed for practice problems both in and outside of class that revisited “older” material and prepared them for the unit exams with integrative questions which combined information from different chapters. I even listed the textbook chapters at the end of the question so that they would know where to find the material if needed.

Along with this, I found that tying material back to central themes in physiology (e.g. structure-function, homeostasis, etc.) also helped the students connect material. I am fortunate that the entry level biology courses at this college teach using the Vision and Change terminology, so the basic themes are not new to them, making integration at least on that level a bit more approachable.

 

5) Solicit student feedback.

Students love to be heard and they love to know that their input matters. And in the design of a new course I want to know what is working and what is not. I may think something is working, but the students may think otherwise. Blank notecards are my best friend in this instance. I simply have a stack at the side of the room and students can or cannot fill them out and drop them in a box. I often ask a specific question and solicit their input after an activity or particularly challenging topic. Of course, the second part of this step is actually reading and taking their input seriously. I’ve often made some last minute changes or revisited some material based on anonymous student feedback, which also ties back to lesson #3.

 

6) Be prepared to spend a lot of time with students outside of the classroom.

Some students are great about speaking up in class and asking questions. Other students are more comfortable asking questions outside of class time. And of course, I found that students of both flavors will think that they know a particular concept, and then find out, usually on an exam, that they do not (but that is probably not unique to an integrative course). So, after the first exam I reached out to every student inviting them to meet with me one-on-one. In these meetings we went through not only the details of the exam, but study skills. Every student needed to be reminded and encouraged to study a little bit every day or at least every other day to maximize retention and success. This also helped create an open-door policy with students who needed and wanted more assistance, increasing their comfort level with coming to office hours and asking for help.

 

As you may have inferred, teaching this type of course takes a lot of time. I’ll be honest and say that I wasn’t necessarily mentally or physically prepared for the amount of time it took to design and run this course, especially in my first year of teaching, but I made it work and I learned a lot. During this process I often discussed course ideas with department colleagues and A&P instructors at other universities. I perused valuable online resources (such as LifeSciTRC.org and the PECOP Blog) for inspiration and guidance. I also found that I spent a lot of time reflecting on just about every lecture, activity, and lab to ensure that the content connections were accurate, applicable, and obtainable by the students. And while I know that the course still has a ways to go, I am confident in the solid foundation I have laid for a real integrative A&P course. And, just as I am doing now with its second iteration, each run will be modified and improved as needed to maximize student learning and success, and that is what makes me even more excited!

Now I turn the conversation over to the MANY seasoned educators that read this blog. Do you have experience designing and teaching an integrated A&P course? What advice do you have for those, like me, that are just starting this journey? Please share!

Teaching High Level Learning Goals in Science Classes: A Lesson from Librarians

Bloom’s Taxonomy provides a way to classify learning outcomes into lower order and higher order goals. On the lower end of the spectrum we ask students to remember, understand, and apply by doing tasks such as define, list, explain, and interpret. On the higher end of the spectrum, we want students to analyze, evaluate, and ultimately create by doing tasks such as organize, compare, critique, and design (1). As educators, we all want to push our students toward the highest levels of Bloom’s Taxonomy, but how do you teach someone to create? It feels like a daunting task. I don’t think anyone ever attempted to directly teach me these higher-level skills, but instead I somehow learned them in graduate school by trial and error (in the form of a lot of red writing on drafts that I submitted to my thesis advisor). This is why I was so excited to discover the synthesis matrix. A synthesis matrix is a table that is set up to extract relevant information from sources, which can include non-scholarly, scholarly, and even student generated data. It provides a way to organize research that allows for easy comparison of the key information from many sources (3, 4, 5). I first learned about the synthesis matrix when I was teaching First Year Seminar (FYS) at Dickinson College. Learning outcomes for FYS include the ability to critically analyze information from multiple perspectives and use that information to create clear academic writing (2). Using class time to teach these skills was very different from what I typically do in my biology classes where it is a struggle just to keep up with the vast amount of content. Therefore, it is an understatement to say that I was out of my element teaching FYS. Fortunately, each FYS class at Dickinson is assigned to librarians. I was fortunate to have Dickinson librarians Nick Lonergan and Jessica Howard help design assignments and teach methods that help students achieve the FYS learning goals. Nick and Jessica designed a synthesis matrix assignment to help students find relevant non-scholarly and scholarly sources and extract information from the sources to help them compare viewpoints on different concepts found in each reference. In this case, the synthesis matrix was used as a homework assignment to prepare students to organize and synthesize information from multiple references in future writing assignments. The power of the synthesis matrix immediately hit me as I realized that this is what experts do in their heads. Many years of reading and analyzing both the work of others and our own research leads to the formation of a mental synthesis matrix that we can pull from as needed in our respective fields. I think my life would have been a lot easier if I knew about the concept of a paper synthesis matrix in graduate school. Since my discovery of the synthesis matrix in FYS, I have used it in different ways in all of the biology classes I teach at Dickinson College including Introductory Biology (Biology 132), Physiology (Biology 333), and Molecular Pathophysiology, which is a research and writing intensive class (Biology 433). Some ways I have used it include:

 

  • Homework assignment: On the simplest level, the synthesis matrix can be used to assess student ability to find appropriate references and extract relevant information from those references. An example of this is described above for FYS and I can easily see this working well in Introductory Biology classes. I have also done this in Molecular Pathophysiology (Biology 433) as a homework assignment prior to assigning a literature review writing assignment.

 

  • Classroom Activity: In Physiology (Biology 333), I have lab groups (6 groups of 4 students each) find a primary publication on a topic related to an upcoming lab project and analyze it for specific information related to research methods and results. In order to avoid overlap and make sure they found the right type of paper, I have the students email the paper they found for approval. If two groups found the same paper or if it is not the right type of source (for example, some students will try to use a review), I will ask them to find another paper. In lab I draw a synthesis matrix on the board and distribute blank handouts of the same synthesis matrix. We then go around the room and as students report their findings, I fill in the synthesis matrix. When it is done, I demonstrate how to use the matrix to synthesize the results of multiple references to come to overarching conclusions and design new experiments. We use this to guide the design of a class research project and in future writing assignments.

 

  • Model Creation: The most complex way I have used the synthesis matrix is in Molecular Pathophysiology (Biology 433). As a research based Writing in the Discipline (WID) class, we focus all of our attention on analyzing primary literature and doing novel experiments in lab. Throughout the semester, I encourage students to draw their own textbook style models of what data show. This can be done by synthesizing results from a single primary publication (if the authors did not already generate a model), multiple primary publications (as seen in review articles), and even by incorporating student lab results with published results. The synthesis matrix can be set up to accommodate all of these approaches. For example, instead of labeling columns by reference #, columns can be labeled by figure # for a single primary publication. Similarly, a column for class lab results can be added to incorporate class results (Figure 1). This is my favorite way of using the matrix. It is so powerful for students to see how one small experiment they did fits in with the big picture of what others have published.

Of all the teaching methods I have tried over the years, the synthesis matrix is the closest I have come to teaching students how to think like an expert. It has also allowed me to do a better job of breaking the research and writing process down into component parts. If you tell a college senior to write a one page introduction section of a scientific paper with 5 references, many of them think they can produce one page of writing in a couple of hours (I know I thought that as a senior in college!). However, if you force them to do a synthesis matrix that includes analysis of the relevant information in 5 primary papers prior to writing about them, they quickly realize how much work is involved.

 

Ultimately, the most important lesson I learned though all of this is that teaching in science classes can benefit greatly from methods used in classes outside of our discipline. If you Google “synthesis matrix”, it is a commonly used method promoted on Library, Academic Coaching, and Writing Center websites at many colleges and universities (3, 4, 5). However, I never heard of it until librarians introduced me to it while teaching FYS. Interacting with scholars outside of my discipline has helped me to integrate the teaching of higher level learning goals alongside lower level learning goals related to content in my classes.

Graduate Student Ambassadors: An APS Effort to Increase Involvement in Professional Societies

The Graduate Student Ambassador (GSA) program was organized by the American Physiological Society’s (APS) Trainee Advisory Committee in 2015. The goal of the program is to train graduate students to act as liaisons between APS and local undergraduate and graduate students. GSAs visit schools in their local area to share their experiences as graduate students, discuss physiology careers and the benefits of an APS membership, and encourage students to consider becoming a member of APS. The program has a unique, symbiotic relationship in that GSAs learn valuable outreach, public speaking, and leadership skills, while APS receives promotion of their awards, programs, and memberships. One particular goal of the GSA program is to recruit and retain individuals from under-represented communities. This is the aim that attracted me to the program.

 

As a first-generation college student, I was raised in a very low socioeconomic background. My exposure to careers was limited and like countless other young girls, I grew up with a short supply of role models who looked like me. While most of my public school teachers were female, the science labs and principal’s offices were considered masculine domains. In my mind, a scientist was that image we all remember of the mad chemist brewing his potions in a lab, hair all in disarray. Although I got the messy hair right, I couldn’t picture myself as this version of a scientist. I didn’t know anything about college because nobody in my life had ever been to one. I certainly didn’t know what a Ph.D. was at the time. By luck and happenstance, I wound up at the University of Kentucky for my undergraduate studies as a nontraditional student following community college. UK is a Research 1 institution, so I was exposed to the scientific method from the start. However, looking back, I’ve always wondered what if I had attended a different university? Would I have ever found my niche in research? And, thus, is the goal of the GSA program: to expose students to careers in research and promulgate the ways in which APS can assist them in these pursuits.

 

When I first got wind of the new GSA program, I was quick to apply. From the beginning, I was excited by the prospect of sharing my experiences as a graduate student with undergraduates. I knew I wanted to visit less research-intensive universities and try to reach under-represented students, first-generation college students, and students from low socioeconomic backgrounds. I recognized the need for diversity in STEM and wanted to contribute to efforts being made to increase it. According to the National Science Foundation, while blacks and Hispanics constitute 36% of the US resident population ages 18-24, they only represent 17% of enrolled graduate students. There is even less representation at the level of doctorate holders (Figure 3). Ethnic and cultural representations in science do not match their share in the US population. However, it is absolutely essential to the growth of STEM to sample from all groups of people.

 

Science is meant to be an objective process, but much of science has been shaped by individuals of a similar background. This not only halts progress but can actually hurt it. For example, the standard medical treatment for breast cancer used to be radical mastectomies. It wasn’t until female voices were welcomed that alternative treatments were implemented—treatments that allowed women to keep their breasts and have been shown to be just as, if not more, effective. Progress was made because of a different perspective. The same is true of drug development, our understanding of sex differences in cardiovascular disease, even air-bag design which was initially tailored to a man’s height and thus not as effective for women. A diverse and inclusive program can promote widely applicable and lifelong learning so that historically under-represented groups can contribute to future breakthroughs with a new perspective. If fields are not diverse and inclusive, we are not cultivating potential but instead losing talent.

 

Berea College, the first coeducational and interracial college in the south, is an example of an ongoing effort to increase inclusion. This school, located in Berea, Kentucky, is a 4-year university that offers a tuition-free education to every single student. They enroll academically promising, economically challenged students from every state in the U.S. and 60 other countries. Over one third of their student population are of color, 8% are international, and 70% are from the Appalachian region and Kentucky. They are inclusive regardless of sexual orientation, gender identity, disability, race, citizenship status, etc. Despite not being a research intensive university, they have an excellent science program with a newly built Natural Sciences and Health building featuring state-of-the-art teaching laboratory equipment. They also encourage students to participate in the Kentucky Biomedical Research Infrastructure Network, a program designed to support undergraduate students in biomedical research, promote collaboration, and improve access to biomedical facilities.

 

I wanted to visit Berea to share my experiences as a graduate student, discuss the different career paths within physiology, and provide interested students with information about beneficial awards and programs offered through APS. Many of the students I spoke with didn’t know much about graduate school or obtaining a Ph.D. They seemed intrigued by my experience as a teaching assistant to fund my program. Berea College offers a unique work program at their school where students work as part of their tuition-free enrollment. Some act as teaching assistants in their courses, giving these students the experience they need to enter a funded graduate program with a teaching component. A lot of the students didn’t realize, though, that you could simply apply to a doctoral program with a bachelor’s degree—they thought you needed to obtain a master’s degree first. Most of the students were particularly interested in the undergraduate summer research programs offered through APS, such as the STRIDE fellowship. They wanted to know more about the Porter Physiology Development Fellowship for graduate students. I was also very excited to share with them the Martin Frank Diversity Travel Fellowship Award to attend the Experimental Biology conference.

 

I had a meaningful and productive visit to Berea College. My next step will be visiting a local community college, another area where efforts to promote diversity and inclusion are progressing. Community colleges are also an excellent place to reach nontraditional students, such as myself. These students sometimes transfer to larger universities to finish their bachelor’s degree, but being a transfer student often doesn’t allow for exposure to research as an undergraduate. I hope to encourage these students to pursue careers in physiology.

 

If you’re interested in contributing to this mission, consider applying to become a GSA. The position is a 2 year term and requires you to attend Experimental Biology each year of your term. The applications for 2019 are currently under review.

Affective Teaching and Motivational Instruction: Becoming More Effective Educators of Science

As educators, we’re intimately familiar with learning objectives such as, “Using Fick’s principle, calculate the diffusion of a substance across a membrane.” Also, as scientists, we are familiar with technical objectives such as, “Using a micropipette, transfer 5μL of Solution A into the chromatography chamber.” In terms of learning conditions, the first is an intellectual skill and the second is a motor skill.1 One area in which we don’t often give much thought is the third type of skill that was identified by Gagné and Medsker — the affective skill. This is the area that is most often neglected by educators because it is the hardest to evaluate and quantify. We can’t explicitly say to a student, “By the end of the semester you will develop a love of physiology.” We can hope to achieve this through the semester, but as educators, the best that we can do is hope to instill these attitudes, choices, and values in our learners that persist beyond our brief time with them in the classroom.

Instilling attitudes in our learners is a complex goal. This is, in part, because stating an affective goal is at times counterproductive to the goal and interferes with learning. In the example above, it is clearly ridiculous to expect that all students will leave our classrooms with a true passion for our subject matter. Some clearly will, but others will not. That will be shaped by the attitudes with which students enter our classrooms. Those attitudes consist of the knowledge that a learner has about a subject – the cognitive aspect, how the person feels about the subject — the affective aspect, and how the person behaves in response to those influences — the behavioral aspect.2 So despite our best interests to instill a care for the animal and human models we frequently use in experiments, it is completely beyond our ability to control the behavior of our learners outside of the classroom. That doesn’t mean that we shouldn’t still try because the majority of our students will come away with those lessons intact. Additionally, affective learning is difficult to assess. We can test the knowledge and skills necessary and ask about student feelings3, but at the end of the day, our students will make a choice on their behaviors on their own. For that reason, we should not make affective learning objectives part of our formal instruction plan. Because there are so many methods that depend on the affect you might want to influence, I’m going to focus on two areas that are most common: attitude and motivational instruction.

 

Katz and Stotland identified five types of attitudes.4 These types of attitudes vary with differing levels of affective and cognitive components, but the key takeaway is that individual experiences and the results and consequences of previous choices dramatically shape the attitudes with which our learners enter our classrooms. Reward for behavior not only reinforces the behavior, but also the cognitive and behavioral components that drive that behavior.1 When we focus purely on the cognitive and the motor skill aspects of learning, we can often get away with a fair amount of do-as-I-say-not-as-I-do-style instruction. The problem with this is that students look to the faculty and other instructors for role model behavior.  Thus, the more accurately that we reflect the attitudes that we want to instill in our learners, the more the students will reflect those ideals.3 One of the easiest ways to bring about these changes of attitudes are through in-class discussions.5 This positive benefit is most likely due to differences that are raised during discussion, sometimes prompting the discovery of a discrepancy between existing attitudes in a learner and new facts that are being presented. The learners then have a choice on how to adapt to the new desired attitudes. Most importantly, never underestimate group acceptance of attitudes, as immediate social reinforcement can be a powerful driver in solidifying attitudes.

 

Having discussed attitude, motivational instruction is another key area that is relevant to affective learning. No two students enter the classroom with the same motivation. One student may be enrolled in your class because of a deep passion for your subject matter while another is there simply to satisfy a requirement for their major. This mix of intrinsic and extrinsic motivations will drive the overall outcomes of affective learning. The student who is highly motivated by an intrinsic interest in your subject or the student who is extrinsically driven by the reward of a good grade (or fear of a bad grade) will generally excel in class, albeit for different reasons. The student who is there out of obligation to meet a requirement may have very little motivation to do anything beyond what is required of them to get by. To help with those students who are lacking in motivation, JM Keller broke motivational instruction into four components: attention, relevance, confidence and satisfaction.6 Gaining the attention of students through demonstrations, discussions, and other active learning techniques may help keep student motivation high. Practical application of concepts and ideas will generally inspire higher motivation than abstract or arbitrary examples.7 Keeping the material relevant will generate motivation for intrinsic learners by providing self-improvement and for the extrinsic learners by providing a reward, such as doing well on the exam. Confidence is a harder area to approach, as students must first believe they are capable of meeting the stated objectives. Making the material too easy will not lead to feelings of accomplishment, while making the material too challenging will undermine confidence in all learners.1 Finally, satisfaction can be achieved by learners of all types, regardless of motivation type when outcomes match objectives. Keeping motivation high by providing opportunities to apply learning will drive further motivation to continue learning.

Last week I completed a comprehensive review of our capstone thesis writing course, which has changed dramatically over the past year and a half while I have been the course director. Initially, the goal of the course was to have students write a literature research paper on a physiological topic of their choosing where their grade was entirely dependent upon the finished paper. The students were frequently frustrated with a lack of guidance in the course and the faculty regularly complained about the burden of reading papers of sometimes-questionable quality. Clearly there were issues with the affective components of this course from both the student and faculty side. I’ve de-emphasized the actual paper and refocused the course on the process of writing with stated learning outcomes such as: 1) Develop the language that helps us talk about science; 2) Strengthen research skills to become educated consumers of science; and 3) Gain specialized knowledge in a selected area of physiological research. Focusing the course in this way has yielded measurable results in course evaluations and faculty perceptions of paper quality from the students. By focusing on the affective components of writing and giving students more opportunities to apply their new skills, overall satisfaction has improved. Like all works of science, though, this course continues to evolve and improve. In short, to be effective teachers, we need to go beyond the intellectual and motor skills and make sure we address the affective learning of our students as well.

Scientific Literacy: A Challenge, a Task, a Poem

Scientific literacy allows citizens to get involved in issues and ideas related to science as a reflective citizen[1]. A scientifically literate person can:

  1. Recognize, offer and evaluate explanations for a variety of scientific and technological phenomena
  2. Describe and evaluate scientific research and propose ways to answer questions and solve problems following the scientific method
  3. Analyze and evaluate data, concepts and arguments in a variety of contexts, reaching appropriate conclusions for the data received[1]

 

The challenge

Quality education is the key to achieving literate societies. Unfortunately, scientific literacy is generally very low in most developing countries. Results of the PISA tests, for example, reveal that competencies in mathematics and sciences in developing countries are below the average of the countries evaluated[2]. This has enormous consequences for the communities by negatively impacting their political, economic and social decision-making.

 

Figure 1. Performance in mathematics and science of different countries in the 2015 Pisa tests. Images Taken from http://www.oecd.org/pisa/.[2]

The task

It is very important to open spaces for the general community in developing countries to learn about the practice of science. Many scientific organizations develop training activities that are usually directed at specialized audiences. For this reason, it is important to highlight the task of scientific associations that are concerned with bringing science to the general community such as the American Physiological Society through events such as PhUn week. In the particular case of Colombia, the Colombian Association for the Advancement of Science (ACAC) organizes every two years a very large science fair “Expociencia” that is visited by more than 40,000 elementary, middle and high school students.

 

These science fairs have several objectives:

  1. Allow students to present the results of scientific projects. Students are exposed to an essential component of science, sharing and communicating research. In addition, they have the opportunity to learn from their peers and receive feedback from more experienced researchers.
  2. Open the doors of academic, governmental or industry laboratories to the community. Visitors have the opportunity to know what scientists do, interact with them, expose their visions about science. In addition, visitors can express doubts they have about different concepts, and sometimes they can find answers to their questions.
  3. Generate academic spaces so that researchers can discuss how to work with the community, address their most pressing needs and communicate their results to the public.

Recently with the support of the Faculty of Medicine of the Universidad de los Andes, I had the opportunity to participate in Expociencia[3]. It was gratifying to see how the children ran from one side to the other having the opportunity to learn about electronics, physics, programming, biology, medicine and anthropology. These children are like sponges that quickly absorb the information they receive and are willing to ask questions without filtering them through mechanisms that adults have learned. In addition, Expociencia promotes spaces for university students to share their experiences and for a moment to be role models for school students. I believe that many lives are changed thanks to the experience of living science.

 

The poem

In the nineteenth century lived a poet who wrote and translated from other languages several of the best-known stories that are known by children and adults in Colombia. His influence on Colombian literature is similar to that of the Grimm brothers in Europe. The name of this writer was Rafael Pombo. A few weeks ago, thanks to my son, I had the opportunity to learn that he also wrote about the importance of knowledge and science. On this occasion I want to share a personal translation of one of Rafael Pombo´s poems, that can be used to discuss with small children and adults the importance of science in our lives.

 

THE CHILD AND THE OX

Rafael Pombo (1833-1912)

The boy

 

-What do you think about all day

Lying on the grass?

You seem to me a great doctor

Enraptured in his science.

 

The ox

-The science, dear child

It is not what feeds me;

That is the fruit of study,

With what God gives humans.

 

Out thinking for me,

Poor animal, hard enterprise;

I prefer to make thirty furrows

Before learning two letters.

 

Chewing well, I care more

that a lesson at school.

With the teeth, I chew,

You, child, with your head.

 

But if you want to be wise

Hopefully seeing me you´ll learn

To ruminate, and ruminate a lot,

Every bit of science.

 

Digesting, not eating,

It is what the body takes advantage of,

And the soul, invisible body,

has to follow such a rule.

 

Without ruminating it well, do not swallow

Not a line, not a letter;

The one who learns like a parrot,

Ignorant parrot stays.

Collaboration is the Key to Success in Publishing Your Work

As an Assistant Professor, you are under a lot of pressure to teach new classes, perform service and of course publish. Often times you do not have a mentor to guide you and you are off on your own pathway to tenure. While I had many good ideas about some teaching research I wanted to perform with my students I needed help in executing a study and publishing my work. While the goal was clear, the plan and the execution were not. Where to start was the biggest and most difficult hurdle.

I assumed incorrectly that the best way to be successful in publishing was to do it on my own. After all, I would only be accountable to myself and need not worry about collaborators who might be hard to reach and would take a long time to complete their portion of a manuscript. I tried this path initially and it was incredibly difficult as I could only work on one project at a time. The turning point came when I attended an Experimental Biology (EB) meeting Teaching Section symposium several years ago; I vividly recalled an excellent presentation where the speaker showed us an elegant study of how he used active learning and student grades improved. This talk inspired me and I got excited to try this with my class by performing a similar study. The excitement abruptly ended when he stated the two sections of students he used for his study had 250 and 300 students respectively. My own classes are between 12-20 students, quite small in comparison and I was completely disheartened thinking it would take years of study before I surveyed that many students. After the talk, I went up to him to ask a question, there was someone in front of me that asked the question that I had planned to ask. She said “I have small classes and for me to do a study of significance would take years”. I chimed in “I am in the same situation”. He answered us both with one word “Collaborate”. I walked away disheartened as I did not know anyone that I could collaborate with on a study.

After some time to reflect that this course of action was what I needed I developed an active plan to execute at the next EB meeting. At the Claude Bernard Lecture, I introduced myself to Barb Goodman. This was an excellent choice, as Barb knows everyone and she was kind enough to introduce me to everyone who approached her. From there my confidence grew. The next smart decision I made was to sit in the front during the lecture and all future Teaching Section Symposia. Do not hide in the back as people sometimes come in late and this can be distracting. In the front of the room are the friendly people who are very happy to talk with you and share ideas.

The next step was to follow the program and attend the Teaching Section luncheon. At this event, a small group of people dedicated to teaching and student success sit and talk about the different classes they teach and share ideas about teaching challenges. The tables are small and round so you can meet everyone at your table. Another key event to attend at EB is the Teaching Section Business meeting and dinner. At the dinner, you get a chance to meet more people in a relaxed setting. Some of the attendees have attended the other events and this is a great way to practice your recall and talk with them on a first name basis.

The final step in meeting people with whom to collaborate is to participate in an Institute on Teaching and Learning (ITL). There have been three of these meetings so far (2014, 2016 & 2018) and the meeting actively encourages you to meet new people at each meal and form new collaborations. Through this meeting, I met many of my collaborators and successfully published abstracts and papers (listed below), received one grant, was a symposium speaker, and chaired a symposium. The meeting is energizing as the program is packed with new ideas and teaching strategies to try in your classroom. It is easy to ask questions and be an active participant in the discussions.  Thus, taking advantage of a number of opportunities for physiology educators through the American Physiological Society can be just the push you need to get going on a successful promotion and tenure process.  Join the APS and its Teaching Section to keep up-to-date on what is going on in physiology education.
