Together or Apart? Lecture with Laboratory, or Taken Separately?

Think back to your days as a college student majoring in science. Was your college on the smaller scale such that your professor met with you weekly for both your lecture and laboratory in chemistry, biology and physics? Or was your university on the large size, and while you sat among dozens or even hundreds of your peers in an auditorium where your professor lectured, you then met weekly in a smaller laboratory session conducted by teaching assistants? Our past experiences as students may or may not bear similarities to our professional career teaching environment at present.

As college professors in biology, or related science disciplines, our student enrollment in the major and the headcount of part-time versus full-time faculty have likely dictated the course schedule each semester. Such quantitative data, meshed with the physical resources of chairs in a classroom and square footage of laboratory space for teaching purposes, may be the major drivers of curricular practices. Pedagogical tradition perhaps accounts for science course scheduling practices as well. Budgetary matters too weigh heavily on decisions to maintain the status quo, or to experiment with test piloting the implementation of emerging course designs.

I teach at a mid-sized public university that offers graduate degrees alongside our more populous undergraduate majors. Our biology majors number approximately 1,000. Our faculty include part-time adjuncts, full-time lecturers and tenured/tenure-track professors. We do not have graduate teaching assistants in the classroom. Most often the assigned faculty teach both their lecture and laboratory sessions for a given course. A recent trend in our college has been to identify traditional lecture/laboratory courses that could be split such that students enroll in completely separate courses for the lecture versus the laboratory. For example, our microbiology course that used to be one combined course meeting twice weekly for lecture and once weekly for laboratory is now two distinct courses, laboratory versus lecture, although both are taken in the same semester, each course posts an individual grade on the transcript.

When asked to consider if any of the courses I teach would or would not be appropriate for separation of lecture from laboratory, I went to the pedagogical literature to see what I could find on the topic. Where science courses are combined into a single course (one grade) with lecture and laboratory, the lecture may be to a large scale audience, while the labs are disseminated into smaller break out groups led by either the lecture faculty or else another faculty member or teaching assistant. On the other hand, a science “course” may have a completely separate course number where students enroll and earn a grade for lecture, and a distinctly different course number where they enroll and earn a separate grade for the laboratory. Knowing these two variations exist, the literature reveals other alternatives as well.

A paper in the Journal of Scholarship of Teaching and Learning evaluated college introductory biology courses where either the same instructor teaches both the lecture and laboratory sessions versus those where there are different instructors for the lecture versus the lab. The author reports “no general trend indicating that students had a better experience when they had the same instructor for both lecture and laboratory than when the lecture and laboratory instructor differed (Wise 2017).” In fact, he states that students may even benefit from having different lecture and laboratory instructors for the same course as such would afford students exposure to instructors with different backgrounds and teaching styles (this paper’s doi: 10.14434/josotl.v17i1.19583).

When I was a teaching assistant during my graduate school days, I developed my teaching style by trial and error as the TA for the laboratory session break outs from the professor-led large auditorium style lectures for the undergraduate first year students majoring in biology. That was the early 1990s, and it was a mid-sized private university where at the same time they were “experimenting” with upper level undergraduate laboratory classes that were lab only. They called them “super labs” and they were not attached to a concurrent lecture course. Indeed, a 2005 paper in Biochemistry and Molecular Biology Education by D.R. Caprette, S. Armstrong and K. Beth Beason entitled “Modular Laboratory Courses” details such a concept whereby the laboratory course is not linked to a lecture (doi/epdf/10.1002/bmb.2005.49403305351). These modular laboratory-only courses are shorter in duration, ranging from a quarter to a half of semester, for 1 or 2 academic credits. Their intent is to apply the learning of specific skills, methods and instrumentation in their undergraduate biology and biochemistry curriculum. Of note, they recognized that their transition to such modular short-term laboratory courses was eased by their academic program already having their traditional curriculum with individual laboratory courses separate from the lecture courses.

Studio courses had in my mind been those taken by the art majors and other fine arts students. In the literature, however, there is an integrated “studio” model for science courses. A paper in Journal of College Science Teaching details how a small private college converted their Anatomy & Physiology I course, among others, from traditional lecture/laboratory courses to the integrated studio model. Their traditional twice weekly 75 minute lectures with 60 students and 150 minute breakout laboratories with 16 students per section, was reconfigured to 30 students meeting with the same instructor and teaching assistant twice weekly, each for 2 hours. These longer duration class sessions each consisted of, for example, 20 minutes lecture followed by 30 minutes of a context-linked laboratory, and then 20 minutes lecture followed again by 40 minutes of a linked laboratory They report fewer course withdrawals and unsatisfactory grades and cite that students felt “engaged and active” as did instructors who spoke of “immediate application and hands on” activity in the interactive classroom (Finn, Fitzpatrick, Yan 2017; https://eric.ed.gov/?id=EJ1155409).

Based on my experience with comprehension by students with the content delivery, I have decided to redesign my upper level undergraduate Cell Physiology course such that the cell physiology lecture will be a standalone 3 credit course, and students will be encouraged to take either during the same semester or the following semester, the 1 credit cell physiology laboratory course. When viewed thru the course scheduling and facilities lenses, this “split” will afford more students to enroll in a single lecture course section, while then having multiple smaller capacity laboratory course sections. As this is an upper level elective, students may find that a 3 + 1 credit option as well as a 3 credit only option suits their needs accordingly. And they can decide for themselves, together or apart, lecture with laboratory, or taken separately.

The Olympics, sex, and gender in the physiology classroom
The recent Tokyo Olympic Games present an opportunity for a number of intriguing discussions in a physiology classroom.  Typical discussion topics around the Olympic Games involve muscle strength, muscle power, aerobic fitness, bioenergetics, and a number of other physiological factors that determine athletic performance.  Coronavirus, immunity, disease transmission, and similar topics may be unique areas of discussion related to the Tokyo Olympic Games.  Another topic that has been prevalent in the news for the Tokyo Olympic Games is the role of sex and gender in athletic competition.

Before and during the Tokyo Olympic Games several athletes were featured in news headlines due to either gender identity or differences of sexual development (DSD, also sometimes called disorders of sexual development).  Male-to-female transgender athletes competing in women’s sports in the Tokyo Olympic Games include weightlifter Laurel Hubbard, archer Stephanie Barrett, cyclist Chelsea Wolfe, soccer player Quinn, and volleyball player Tifanny Abreu, (1, 2).  There have also been news stories about Caster Semenya, Christine Mboma, and Beatrice Masilingi being ineligible to participate in the Olympics due to their DSD causing their serum testosterone concentrations to be above the allowed limits for female athletes (3, 4).  In addition to physiology sex and gender are interwoven with culture, religion, and politics, so how to discuss sex and gender in the physiology classroom needs to be carefully considered by each instructor depending on the campus climate, policies, and individual comfort level with walking into these potential minefields.  However, sex and gender in sports are very appropriate topics to discuss from a physiological perspective.

Although sex and gender have been used interchangeably in common conversation and in the scientific literature, the American Psychological Association defines sex as “physical and biological traits that distinguish between males and females” (5) whereas gender “implies the psychological, behavioral, social, and cultural aspects of being male or female (i.e., masculinity or femininity)” (6).  Using these definitions can be helpful to draw a clear distinction between gender (and/or gender identity) as a social construct and sex as a biological variable, which can help focus the discussion on physiology.

As reviewed by Mazure and Jones (7) since 1993 the NIH puts a priority on funding research that includes women as well as men in clinical studies and includes an analysis of the results by sex or gender.  Mazure and Jones (7) also summarized a comprehensive 2001 Institute of Medicine sponsored evaluation that concluded that every cell has a sex.  A 2021 Endocrine Society scientific statement provides considerable information on the biological basis of human sexual dimorphism, disorders of sexual development, and lack of a known biological underpinning for gender identity (8).  On August 12, 2021 a PubMed search using the term “Sex Matters” (in quotation marks) returned 179 results, with many of the linked papers demonstrating the importance of sex for health, disease, and overall biological function (without quotation marks there were 10,979 results).  Given that there have been various discussions in the news media and across social media blurring the distinction between sex and gender, it is very important that students in physiology understand that sex in humans is an important biologically dimorphic trait of male or female.

Relevant to a discussion of the Olympic Games, the differences in performance between male and female running has been analyzed for world’s best and world’s 100th best (9), annual world’s best performance (10), world record performance (11-13), Olympic and elite performance (13-16), High School performance in CA, FL, MN, NY, and WA (17), and 100 all-time best Norwegian youth performance (18).  Hilton and Lundberg (19) also provided an excellent review of the large differences in athletic performance between men and women in numerous sports.  Overall, by mid-puberty males outperform comparably aged and trained females by 10-60%, depending on the sport (see figure 1 of Hilton and Lundberg, reproduced here with no changes under the Creative Commons license https://creativecommons.org/licenses/by/4.0/).

 

Hilton and Lundberg (19) also reviewed the present state of research regarding the effects of male-to-female hormone treatment on muscle strength and body composition and concluded that men typically have 45% more muscle mass than women, and male-to-female hormone treatment reduces muscle mass by ~5%.  These authors also concluded that men typically have 30-60% higher muscle strength than women, and male-to-female hormone treatment reduces muscle strength by 0-9%.  Overall, Hilton and Lundberg (19) conclude that transwomen retain considerable advantages over cisgender women even after 1-3 years of male-to-female hormone treatment.  Harper at al. (20) also reviewed the research regarding the effects of male-to-female hormone treatment on muscle strength and body composition and came to the same conclusions as Hilton and Lundberg.  Harper et al. (20) further concluded that male-to-female hormone treatment eliminates the difference in hemoglobin concentrations between cisgender men and women.  In a single research project, Roberts et al. (21) observed that before transition male-to-female members in the US Air Force completed a 1.5 mile running fitness test 21% faster than comparably aged cisgender women.  After 2.5 years of male-to-female hormone treatment the transwomen completed the 1.5 mile running fitness test 12% faster than comparably aged cisgender women. (Figure 1 Hilton and Lundberg)

All of the previously mentioned information is important to consider when asking if transwomen can be fairly and safely included in women’s sports.  It is also important to note that the effects of male-to-female hormone treatment on important determinants of athletic performance remain largely unknown.  Measurements of VO2max in transwomen using direct or indirect calorimetry are not available.  Measurements of muscle strength in standard lifts (e.g. bench press, leg press, squat, deadlift, etc.) in transwomen are not available.  Nor have there been evaluations of the effects of male-to-female hormone therapy on agility, flexibility, or reaction time.  There has been no controlled research evaluating how male-to-female hormone treatment influences the adaptations to aerobic or resistance training.  And there are only anecdotal reports of the competitive athletic performance of transwomen before and after using male-to-female hormone treatment.

The safe and fair inclusion of transgender athletes and athletes with DSD in women’s sports is a topic being debated in many states and countries, and by many sporting organizations including the International Olympic Committee.  In the end, whether it is safe and fair to include transgender athletes and athletes with DSD in women’s sports comes down a few facts that can be extrapolated, lots of opinions, and an interesting but complicated discussion.  This is a worthwhile discussion in a physiology classroom because it allows a good review of the biologically dimorphic nature of human sex.  However, the safe and fair inclusion of transgender athletes and athletes with DSD in women’s sports is also a discussion that should be approached with caution due to the many opinions this topic entails that reside outside of physiology.

Why demonstrating and embracing uncertainty should be a learning objective, especially in uncertain times?

Uncertainty.  We have all heard that word quite frequently lately.  It tends to carry negative connotations and feelings of uneasiness.  It seems the answer to every question these days is, “well, it depends”.  As physiology educators, this is not new to us.  How many times have we answered a student’s broad question with this same phrase?    Regardless of how much active learning is accomplished in the classroom, students at all levels are tasked with preparing for and taking standardized tests.  My children started taking assessments in preschool, multiple choice tests for grading purposes in kindergarten, and state assessment tests in 3rd grade.  Then there will be standardized tests for admissions to college, graduate admissions, and licensing.  It’s no wonder that some students are conditioned to study ‘to the test’ instead of having the goal of truly learning the material, and are hesitant to express when they don’t know something.   I spent the first decade of my career teaching science at the undergraduate level and have spent the last five years teaching in the professional school setting, including medical, dental, and podiatry students.  I have found that these health professions students in particular become especially aware of uncertainty when they start gaining experience with clinical cases and with patients.  I also notice that they are uneasy with uncertainty even from the interactions in the classroom – they are high achieving students and don’t want to be wrong, to be perceived as not knowing an answer or a concept, of maybe feeling like they don’t belong.  In truth, many students have the same questions, and the same feelings, but are hesitant to express them.   It is known that dealing with uncertainty and ambiguity, especially in professions where people are serving patients whose health is at stake, can result in the experience of stress, anxiety, depression, and burnout (1).  Wellness is an important consideration, especially in a climate where things seem to be changing day-to-day and we are provided limited information and answers.  How one deals with uncertainty can lead to life and professional decisions including which career or specialty to pursue.  While this concept is not novel, actually teaching students how to tolerate or even embrace uncertainty is a relatively new concept, one which I think should be made a more purposeful objective in our courses.   What if instead of shying away from admitting we don’t know something, we learn how to accept it, and how to approach the problem to find the most effective answer?  How do we best learn to tolerate uncertainty, and train our students how to cope with and learn from uncertainty?  What are the benefits of embracing uncertainty?   

Bring uncertainty into the classroom Thoughtfully and purposely embedding uncertainty into activities in the classroom does several things.  First, it allows students to learn that not every question has an absolute answer.  Students need help shifting their mindset.  This also encourages students to work with material at higher levels of Bloom’s taxonomy, like evaluation and application.   Additionally, this helps create a culture in the classroom where asking questions and admitting to what we don’t know is a good thing, and brings value to classroom discussions.  This allows students to bring in their own experiences in an attempt to work through a problem and arrive at an answer, enhancing students’ learning.  Students can build their confidence as they find value in embracing the unknown as they learn to navigate the process to find the answers to their questions.   The learning theory constructivism suggests that students build their own learning, that knowledge is built upon knowledge, and that it works best in context (2). This encourages students to bring their own experiences to the learning process, and the result is that each student may bring a different perspective and answer (3).  These principles match well with the intention of teaching how to manage uncertainty.  A goal is for students to be engaged and motivated in an active learning environment, allowing them to share ideas and build their knowledge based on their prior knowledge and experiences.  

Leading to deeper learning To further expand the idea of students building their mental models, activities designed to allow for more open-ended thinking or answers, which build upon each other, can be utilized.  For example, in the cardiovascular physiology component of our medical course, we build on the basic concepts in a series of small group sessions which encourage students to work in their teams to answer questions pertaining to these concepts.  We may start with the principles of hemodynamics but eventually work our way to the integration of cardiac function and vascular function.  These sessions require students to not only recall knowledge, but also apply information in a manner which may lead to uncertainty.  They learn to question the severity of perturbations, the balance of factors which interact, and the cause and effect.  We find students may become frustrated with the “it depends” answer, but they learn how to view the nuance and ask the appropriate questions.  This type of exploration and learning transitions well to more clinical sessions, where students need to know which questions to ask, which tests to order, and which colleagues to consult.    

Demonstrate uncertainty as educators and professionals In addition to our basic science session, I spend a lot of time teaching with clinical colleagues in the pre-clerkship medical classroom.  We have a small cohort of core educators who participate in a special type of small group learning we call Clinical Reasoning Conferences.  The core educators are either basic scientists or clinicians and come from different disciplines, bringing different experiences and expertise to each session. We are always joined by content experts in our sessions with the students as well.  This means that we are likely to be in a session where we are not the content expert, but have immediate access to one. This gives us an opportunity to demonstrate uncertainty in the classroom, to students who feel constant pressure to know everything and to perform at the highest level.  To be honest, it took a while for us to get comfortable with telling the students, “I don’t know”, but that “I don’t know” was, in reality, “I don’t know but let’s get the answer”, which gave us the opportunity to demonstrate how we get the answer.  It could be a reference from the literature, a clinical resource, or a colleague.  Students not only benefit from getting perhaps a more comprehensive answer to their questions, but also knowledge that no one can know everything or even how much is still unknown.  It is imperative in medicine that they learn and practice how to find appropriate information in order to make the most informed decision when it comes to patient care.  These practices have also been shared by other medical educators (1).  Clinical Reasoning Sessions also include students teaching the material to their colleagues, and we make it clear in our expectations that we much rather they describe their process and maybe come up with an incorrect conclusion than have short, although correct, answers which do not demonstrate process and reasoning.  Another goal is to allow the students plenty of chances to practice answering questions of a clinical nature posed by faculty, and allow them to become comfortable asking faculty questions, well before they start their clerkships.    

Manage expectations In my experience, students appreciate the ability to give feedback and share their expectations of their courses and programs.  They also align these with their own expectations of themselves.  Faculty and course directors work to resolve the students’ expectations with their own, and to assist students in forming and revising their expectations of and their role and responsibilities within the course.  Educating during a pandemic has shined a light on and challenged the way we manage these expectations. A word I have heard my colleagues use lately is grace; we should extend grace to our students, to ourselves, and ask for grace from others.  This is another way we can demonstrate how we deal with uncertainty, which can hopefully serve as a soft teaching point for our students.    

Outside of the science classroom Developing skills to help us manage uncertainty extends to outside of our classroom.  We hope that students will take the lessons and continue to use them in other classes, or outside of school altogether.  Medical schools often offer electives, some of which are tied to wellness or extracurricular subjects.  For example, some of our electives include Artful Thinking, in which students hone their skills of observation, application, and context, and Fundamentals of Improv, so that students can work on skills of listening, support, creativity, and quick thinking and response.  Other schools and programs offer similar experiences for students (4,5).  The narrative medicine program emphasizes skills of reflective writing to focus on the human side of medicine, reminding why we’re here in the first place (6).  

Challenging ourselves and encouraging our creativity One of the most important lessons I learned in the transition to remote and hybrid education over the past six months was to face the uncertainty with planning, reflection, and flexibility.  I am the type to have a backup plan to my backup plan, which I realized gave me the flexibility to be more creative in my course design and preparation.  I feel that my courses benefitted from my ability to challenge myself, because of uncertainty, and I intend to continue to reflect and employ what I consider my ‘best practices’ even when we move back into the in-person classroom in the future.   We are exposed to uncertainty every day.  How we choose to frame our mindset, to help our students and ourselves tolerate or even embrace uncertainty can bring benefits both in and outside of the classroom.

Protecting yourself means more than a mask; should classes be moved outside?

Disruption sparks creativity and innovation. For example, in hopes of curbing viral spread by moving classroom instruction outdoors, one Texas University recently purchased “circus tents” to use as temporary outdoor classrooms.

Although circus tents may be a creative solution… solving one problem may inadvertently create another. Moving events outdoors may be effective in reducing viral spread, but it also increases the skin’s exposure to harmful ultraviolet (UV) radiation from the sun. The skin, our body’s largest organ by weight, is vulnerable to injury. For the skin to remain effective in its role of protecting us from pollutants, microbes, and excessive fluid loss – we must protect it.

It is well known that UV radiation, including UVA and UVB, has deleterious effects including sunburn, premature wrinkling and age spots, and most importantly an increased risk of developing skin cancer.

Although most of the solar radiation passing through the earth’s atmosphere is UVA, both UVA and UVB cause damage. This damage includes disruption of DNA resulting in the formation of dimers and generation of a DNA repair response. This response may include apoptosis of cells and the release of a number of inflammatory markers such as prostaglandins, histamine, reactive oxygen species, and bradykinin. This classic inflammatory response promotes vasodilation, edema, and the red, hot, and painful condition we refer to as “sun burn.”1,2

Prevention of sunburn is relatively easy and inexpensive. Best practice is to apply broad spectrum sunscreen (blocks both UVA and UVB) 30 minutes before exposure, and reapply every 90 minutes. Most dermatologists recommend using SPF (sun protection factor) of at least 30. Generally speaking, an SPF of 30 will prevent redness for approximately 30 times longer than without the sunscreen. An important point is that the sunscreen must be reapplied to maintain its protection.

There are two basic formulations for sunscreen:  chemical and physical. Chemical formulations are designed to be easier to rub into the skin. Chemical sunscreens act similar to a sponge as they “absorb” UV radiation and initiate a chemical reaction which transforms energy from UV rays into heat. Heat generated is then released from the skin.3  This type of sunscreen product typically contains one or more of the following active ingredient organic compounds: oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate. Physical sunscreens work by acting as a shield. This type of sunscreen sits on the surface of the skin and deflects the UV rays. Active ingredients zinc oxide and/or titanium dioxide act in this way.4  It’s interesting to note that some sunscreens include an expiration date – and others do not. It is reassuring that the FDA requires sunscreen to retain their original “strength” for three or more years.

In addition to sunscreen, clothing is effective in blocking UV skin exposure. Darker fabrics with denser weaves are effective, and so too are today’s specially designed fabrics. These special fabrics are tested in the laboratory to determine the ultraviolet protection factor (UPF) which is similar to SPF for sunscreen.  A fabric must carry a UPF rating of at least 30 to qualify for the Skin Cancer Foundation’s Seal of Recommendation. A UPF of 50 allows just 1/50th of the UV rays to penetrate (effectively blocking 98%). Some articles of clothing are produced with a finish that will wash out over time. Other fabrics have inherent properties that block UV rays and remain relatively unchanged due to washing (some loss of protection over time is unavoidable) – be careful to read the clothing label.

Some individuals prefer relying on protective clothing instead of sunscreen due to concerns about vitamin D synthesis. Vitamin D activation in the body includes an important chemical conversion stimulated by UV exposure in the skin – and there is concern that sunscreen interferes with this conversion. However, several studies, including a recent review by Neale, et al., concluded that use of sunscreen in natural conditions is NOT associated with vitamin D deficiency.5,6 The authors did go on to note that at the time of publication, they could not find trials testing the high SPF sunscreens that are widely available today (current products available for purchase include SPFs over 100).

Additional concern about use of sunscreens includes systemic absorption of potentially toxic chemicals found in sunscreen. A recent randomized clinical trial conducted by Matta and colleagues investigated the systemic absorption and pharmacokinetics of six active sunscreen ingredients under single and maximal use conditions. Seven Product formulations included lotion, aerosol spray, non-aerosol spray, and pump spray. Their study found that in response to repeat application over 75% of the body surface area, all 6 of the tested active ingredients were absorbed systemically. In this study, plasma concentrations surpassed the current FDA threshold for potentially waiving some of the additional safety studies for sunscreen. The authors went on to note that the data is difficult to translate to common use and further studies are needed. It is important to note that the authors also conclude that due to associated risk for development of skin cancer, we should continue to use sunscreen.

Yet another concern for using sunscreen is the potential for harmful environmental and human health impact. Sunscreen products that include organic UV filters have been implicated in adverse reactions in coral and fish, allergic reactions, and possible endocrine disruption.8,9 In some areas, specific sunscreen products are now being banned (for example, beginning January of 2021, Hawaii will ban products that include oxybenzone and octinoxate). As there are alternatives to the use of various organic compounds, there is a need to continue to monitor and weigh the benefit verses the potential negative effects.

Although the use of sunscreen is being questioned, there is the potential for a decline in use to be associated with an increase in skin cancer. Skin cancer, although on the decline in recent years, is the most common type of cancer in the U.S. It is estimated that more than 3 million people in the United States are diagnosed with skin cancers each year (cancer.net). Although this is fewer than the current number of Americans diagnosed with COVID-19 (Centers for Disease Control and Prevention, July 20, 2020) – changes in human behavior during the pandemic (spending more time outdoors) may inadvertently result in an increase in the number of skin cancer cases in future years.  

While we responsibly counter the impact of COVID-19 by wearing masks, socially distancing, and congregating outdoors – we must also continue to protect ourselves from damaging effects of the sun. As physiologists, we are called upon to continue to investigate the physiological impacts of various sunscreen delivery modes (lotion, aerosol, non-aerosol spray, and pumps) and SPF formulations. We are also challenged to investigate inadvertent and potentially negative impacts of sunscreen including altered Vitamin D metabolism, systemic absorption of organic chemicals, and potentially adverse environmental and health outcomes.

Again, solving one problem may create another challenge – the work of a physiologist is never done!

Stay safe friends!

The COVID-19 pandemic has led to a total and sudden reshaping of the academic landscape across the country, with hundreds of institutions moving administration entirely online and shifting to online instruction for the remainder of the spring semester or for both spring and summer. This sudden transition with practically no time to prepare has major implications for students and faculty alike, and poses serious challenges to a smooth transition as well as effective online teaching on such a large scale. Out of these challenges, two issues in particular are examined here:

  • the disparity in resources and preparedness for effective online teaching 
  • the implications of the migration to virtual classrooms for diversity and inclusion

Disparity in resources and preparedness for effective online teaching

Teaching an online course requires just as much, if not more, time and energy as traditional classroom courses. It also requires specific IT skills to be effective. Some teachers have managed to achieve great success engaging students online. However, many challenges remain for the average teacher. While online teaching has now been embraced by all higher education institutions and the number of classes offered online has seen a steady growth over the years, it should be noted that until now, instructors and students had the choice between brick and mortar classes and virtual ones. Each could then choose based on their personal preferences and/or circumstances. What makes the recent changes so impactful and consequential is that no choice is left to instructors or students, as the move to online classes is a mandate from the higher administration. Whether one is willing, prepared or ready is irrelevant. It is from this perspective that the question of the preparedness to migrate online is worth examining. 

With academic units ordered to move classes online, instructors who had remained indifferent to the growing trend of online teaching have had a difficult reckoning. They have had to hastily move to online delivery, often with a steep learning curve. This challenge has been compounded in some cases by the technology gap for instructors who haven’t kept their IT skills up to date as well as the school’s preparedness to support online teaching. But even instructors who had some familiarity with learning management systems (LMS) and online delivery have faced their share of challenges. We will only mention two sources of these difficulties: 

  • First, students’ expectations in a context of exclusive online teaching are different from when most online classes took place in the summer, and were attractive to students because of convenience and flexibility. With online classes becoming the norm, students in some universities are taking steps to demand that school administrators pay more attention to quality of instruction and maintain high standards to preserve teaching effectiveness. 
  • Second, instructors can no longer use LMS resources just for the flexibility and benefits they afforded, such as in blended classes or flipped classes. Moving everything online thus requires extra work even for LMS enthusiasts.

For students, there have been some interesting lessons. Until now, it was assumed that Generation Z students (raised in the boom of the internet and social media) we have in our classes have tech skills in their DNA and would be well equipped and ready to migrate online. Surprisingly, this hasn’t been the case across the board, and these first weeks have revealed real discrepancies in student IT equipment with varying consequences for online classes. Equipment failure and problems with access to high speed internet emerge as the most serious difficulties on the students’ side. Furthermore, online learning requires independence and often more self-discipline and self-motivation. Most online courses are not taught in real time, and there are often no set times for classes. While this flexibility makes online classes attractive, it can also be a drawback for students who procrastinate and are unable to follow the course pace. If left to themselves, only the most responsible students will preserve their chances of performing well. On this last point, one unexpected issue has been students who have virtually disappeared from their classes since the migration of courses online amid the COVID-19 pandemic. The current transition has thus presented major challenges for teachers and students alike. 

Implications of the migration to virtual classrooms for diversity and inclusion

The second issue we think deserves attention is the way in which educational institutions’ commitment to diversity and inclusion would play out in virtual classes. While they are now among the professed core values of all colleges and universities across the country, implementing diversity and inclusion in an online environment presents a different set of challenges for both instructors and students. In traditional classrooms, the commitment to diversity and inclusion typically translates into the following:

  • A diversity and inclusion statement from the school must be included in the course syllabus.
  • Instructors must remind students a few rules at the beginning of the course, including: recognition that the classroom is an environment where diversity is acknowledged and valued; tolerance of and respect for diversity of views in the classroom.
  • Sensitivity to and respect for diversity (gender, age, sexual orientation, etc.).
  • Students are asked to be courteous and respectful of different opinions.

In moving into a virtual environment, instructors have to think about the challenges of virtual classrooms and their potential impact on diversity and inclusion. For instance, the faceless nature of course participation and asynchronous delivery may make it easier for participants to disregard or neglect diversity and inclusion rules. Teachers need to reflect on ways to ensure that the virtual space of online classes remains an environment that fosters diversity and inclusion. One drawback of online classes is the potential impact of the relative anonymity on social engagement. In a traditional classroom, participants are constrained by the physical presence of their peers in the confined space of the classroom. The closed physical space of the classroom, combined with the instructor’s authority and peer pressure contribute to fostering discipline. Reflecting on the way online teaching impacts the instructor, one faculty noted: “I didn’t realize how much I rely on walking around the room and making eye contact with students to keep them engaged.” As an online teacher, one lacks the ability to connect physically with students, to read emotional cues and body language that might inform about the individuality of a student. Moreover, a good grasp of the diversity in the classroom and of students’ learning abilities is needed to plan instruction, and give each of them the opportunity to learn and succeed.

Drawing from the above considerations, here are some key questions that instructors should consider as they migrate online: What skills do instructors need to properly address diversity and inclusion online? How do instructors include diversity and inclusion requirements in online course design? How to create an inclusive online classroom? How do instructors attend to diverse students’ needs during instruction? How do they monitor behaviors and enforce diversity and inclusion rules during instruction?

While the migration might have been abrupt, instructors need not seek perfection in moving their courses online. As in traditional classes, what matters the most, from the student’s point of view, is constant communication, clear directions and support from their teachers. Students understand the challenges we all face. They also understand the rules in virtual classes, provided we emphasize them.

Involving students in the teaching experience
Karen L. Sweazea, PhD, FAHA
Arizona State University

As faculty, we often find ourselves juggling multiple responsibilities at once. Although many of us are interested in adding hands-on or other activities to our classes, it can be difficult to find the time to develop them. This is where more advanced students who have already taken the class or graduate students can help.

A couple of summers ago I requested the help of an extra teaching assistant in my Animal Physiology course. The role of the position I was requesting was unique as I was not seeking a student to help with grading or proctoring exams. Rather, the role of this student was to help develop in-class activities that would enhance the learning experience of students taking the course.

For each lesson, the special graduate student TA was tasked with finding an existing (ex: https://www.lifescitrc.org/) or creating a new activity that could be implemented in the classroom during the last 10-20 minutes of each session, depending on the complexity of the activity. This enabled me to begin converting the course into a flipped classroom model as students enrolled in the course were responsible for reading the material ahead of time, completing a content comprehension quiz, and coming to class prepared to discuss the content and participate in an activity and/or case study. Special TAs can also assist with developing activities for online courses.

While the benefits of having such a TA for the faculty are clear, this type of experience is also beneficial to both the TA as well as the students enrolled in the course. For the TA, this experience provides an opportunity to develop their own teaching skills through learning to develop short lesson plans and activities as well as receiving feedback from the faculty and students. For the students, this is a great way to build cultural competence into the course as TAs are often closer in age to the students and may better reflect the demographics of the classroom. Cultural competence is defined by the National Education Association as “the ability to successfully teach students who come from a culture of cultures other than our own.” Increasing our cultural competency, therefore, is critical to student success and is something that we can learn to address. Having special TAs is just one way we can build this important skill.

Can the Flipped Classroom Method of Teaching Influence Students’ Self-Efficacy?
Chaya Gopalan, PhD, FAPS
Associate Professor

Self-efficacy is the belief in one’s ability to succeed in a specific situation or accomplish a specific task (Bandura, 1977). Students with high self-efficacy have higher motivation to learn and, therefore, are able to reach higher academic goals (Honicke & Broadbent, 2016). Gender, age, and the field of study are some factors that are known to affect self-efficacy (Huang, 2013). Genetics plays a significant role (Waaktaar & Torgersen, 2013). Certain physiological factors such as perceptions of pain, fatigue, and fear may have a marked, deleterious effect on self-efficacy (Vieira, Salvetti, Damiani, & Pimenta, 2014). In fact, research has shown that self-efficacy can be strengthened by positive experiences, such as mastering a skill, observing others performing a specific task, or by constant encouragement (Vishnumolakala, Southam, Treagust, Mocerino, & Qureshi, 2017). Enhancement of self-efficacy may be achieved by the teachers who serve as role models as well as by the use of supportive teaching methods (Miller, Ramirez, & Murdock, 2017). Such boost in self-efficacy helps students achieve higher academic results.

The flipped classroom method of teaching shifts lectures out of class. These lectures are made available for students to access anytime and from anywhere. Students are given the autonomy to preview the content prior to class where they can spend as much time as it takes to learn the concepts. This approach helps students overcome cognitive overload by a lecture-heavy classroom.  It also enables them to take good notes by accessing lecture content as many times as necessary. Since the lecture is moved out of class, the class time becomes available for deep collaborative activities with support from the teacher as well as through interaction with their peers. Additionally, the flipped teaching method allows exposure to content multiple times such as in the form of lecture videos, practice questions, formative assessments, in-class review, and application of pre-class content. The flipped classroom therefore provides a supportive atmosphere for student learning such as repeated exposure to lecture content, total autonomy to use the constantly available lecture content, peer influence, and support from the decentered teacher. These listed benefits of flipped teaching are projected to strengthen self-efficacy which, in turn, is expected to increase students’ academic performance. However, a systematic approach measuring the effectiveness of flipped teaching on self-efficacy is lacking at present.

Building bridges: Medical physiology teaching in China

Washington, D.C.

The Chinese Society of Pathophysiology hosted the 2019 Human Functional Experiment Teaching Seminar and the Second Human Physiology Experimental Teaching Training Course 25-27 October. Across two and a half days, educators from across China met at Jinzhou Medical University in the province of Liaoning to discuss and workshop the latest ideas in active learning and interactive teaching techniques. In many ways, especially in terms of the esteem in which this meeting is held by its attendees, this meeting was not dissimilar from the APS Institute on Teaching and Learning, which will hold its next biennial meeting this coming June in Minneapolis. For the 2019 meeting, the organizers decided to invite an international speaker, which is how I found myself on a plane headed to China. As part of my visit, not only did I get to attend the workshop hosted at Jinzhou Medical University, but also I was hosted by several of the meeting organizers at their home institutions to see their facilities. In this writeup, I will reflect on some of the observations that I made during the many different conversations that I had with the educators participating in the meeting.

The most common question that I got from my hosts was, “What kinds of technology do you use in your classrooms and labs and how do you use them?” What surprised me the most about this question wasn’t the actual question itself, but the perception that many of the educators at the meeting held that they were lagging behind in the implementation of using technologies as   teaching and learning tools. The large majority of teaching spaces that I visited were equipped with much the same technology as any classroom or lecture hall that I would find in an American university: computers, projectors, large-screen LCD displays, and power at every seat to accommodate student personal electronic devices. While there was the occasional technological oddity, such as a computer here or there that was still running Windows XP, the technology available to these educators was very much on par with the technology I would expect at any modern university, which is why I was surprised that the educators had the perception that they were behind in implementing different technologies. In my conversations with them, I discussed the use of audience response systems like iClicker and PollEverywhere as well as interactive elements like gamification through websites such as Kahoot!, but my emphasis in these conversations was exactly the same as I have with educators at home: we need to make sure that there is a sound pedagogical basis for any engagement we use with our students and that the technology doesn’t matter. I can use 3×5 colored  index cards to create an audience response system that functions as well as (or sometimes even better!) than clickers because no one has any problems with the WiFi while using a 3×5 card. The technology facilitates our instruction and should never drive it for the sake of itself.

A common thread of many discussions was the use of internet technologies in teaching. While there is much to be said about the limitations of the ‘Great Firewall’ of China and the amount of government regulation that occurs over their communications, it’s important to note how little these limitations affect the day-to-day activities of the majority of citizens. There are Chinese versions of almost every single internet convenience that we would take for granted that function at least as well as our American versions. Their social media system has grown to the point that many international users are engaging on their platforms. There are food delivery apps and the local taxi services have all signed on to a common routing system (at least in Beijing) that functions in a similar way to Uber or Lyft. In a side-by-side comparison between my phone and one of the other meeting participants, there is near feature parity on every aspect. From an educational standpoint, however, there are some notable differences. The lack of access to Wikipedia is a notable gap in a common open resource that many of us take for granted and there is not yet a Chinese equivalent that rivals the scope or depth that Wikipedia currently offers. Another key area in which internet access is limited is their access to scholarly journals. This lack of accessibility is two-fold, both in the access to journals because of restrictions on internet use as well as the common problem that we are already familiar with of journal articles being locked behind paywalls. The increasing move of journals to open access will remove some of these barriers to scholarly publications, but there are still many limits on the number and types of journal articles that educators and learners are allowed through Chinese internet systems.

The most common request that I received while attending the educators meeting was, “Tell me about the laboratories you use to teach physiology to your medical students.” I think this is the largest difference in teaching philosophy that I observed while in China. The teaching of physiology is heavily based on the use of animal models, where students are still conducting nerve conduction experiments with frogs, autonomic reflex modules with rabbits, and pharmacological studies in rats. These are all classic experiments that many of us would recognize, but that we rarely use anymore. One key area of the workshops were modules designed to replace some of these classic animal experiments with non-invasive human-based modules, such as measuring nerve conduction velocities using EMG. My response that the majority of our physiology teaching is now done through lecture only was met with a certain degree of skepticism from many of them because the use of labs is so prevalent throughout the entire country. Indeed, the dedication of resources such as integrated animal surgical stations runs well into the hundreds of thousands of dollars per laboratory room set up, and to facilitate the entirety of students each year, there are multiple labs set up at each university. As the use of non-invasive human experiments expands, an equal amount of space and resources are being given to setting up new learning spaces with data acquisition systems and computers for this new task. In this area, I think that we have much to gain from our Chinese counterparts as many of the hardest concepts in physiology are more easily elucidated by giving students the space to self-discover in the lab while making physiological measurements to fully master ideas like ECG waves and action potential conduction.

Upon returning home, I have been asked by nearly everyone about my travel experiences, so I think it may be worth a brief mention here as well. I cannot overstate the importance of having a good VPN service setup on all of your electronic devices before traveling. Using a VPN, I had near-normal use of the internet, including Google and social media. My largest problem was actually trying to access local Chinese websites when my internet address looked like I was outside of the country. I have had good experience with NordVPN, but there are several other very good options for VPN service. Carrying toilet paper is a must. There are lots of public restrooms available everywhere in the city, but toilet paper is either not provided or available only using either social media check-ins or mobile payments. For drinking water, I traveled with both a Lifestraw bottle and a Grayl bottle. This gave me options for using local water sources and not having to rely on bottled water. The Lifestraw is far easier to use, but the Grayl bottle has a broader spectrum of things that are filtered out of the water, including viruses and heavy metals, which may be important depending on how far off the tourist track you get while traveling. My final tip is to download the language library for a translator app on your mobile device for offline use so that you can communicate with others on the streets. When interacting with vendors and others not fluent in English, it was common to use an app like Google Translate to type on my device, show them the translated results, and they would do the same in reverse from their mobile device.

One of the themes across the meeting was building bridges — bridges between educators, bridges between universities, bridges across the nation and internationally. I’m glad to have had the opportunity to participate in their meeting and contribute to their conversation on building interactive engagement and human-focused concepts into the teaching of physiology. Overall, the time that I spent talking to other educators was useful and fantastic. Everyone I met and interacted with is enthusiastic and excited about continuing to improve their teaching of physiology. I left the meeting with the same renewed energy that I often feel after returning from our ITL, ready to reinvest in my own teaching here at home.

The Benefits of Learner-Centered Teaching

In the US, Students at Still Facing Struggles in the STEMs

Literacy in the World Today:
According to the United Nations Educational, Scientific, and Cultural Organization (UNESCO), there are approximately 250 million individuals worldwide, who cannot read, write, or do basic math, despite having been in school for a number of years (5, 8). In fact, UNESCO, is calling this unfortunate situation a “Global Learning Crisis” (7). The fact that a significant number of people are lacking in these fundamental life skills regardless of attending school, shows that part of the problem lies within how students are being taught.

Two Main Styles of Teaching – Learner or Teacher-Centered

Learning and Teaching Styles:
It was due to an early exposure to various education systems that I was able to learn of that there were two main styles of teaching – Learner-centered teaching, and Teacher-centered teaching (2). Even more fascinating, with the different styles of teaching, it has become very clear that there are also various types of learners in any given classroom or lecture setting (2, 6, 10). Surprisingly however, despite the fact that many learners had their own learning “modularity” or learning-style, instructors oftentimes taught their students in a fixed-manner, unwilling or unable to adapt or implement changes to their curriculum. In fact, learner-centered teaching models such as the “VARK/VAK – Visual Learners, Auditory Learners and Kinesthetic Learners”, model by Fleming and Mills created in 1992 (6), was primarily established due to the emerging evidence that learners were versatile in nature.

VARK Model of Learners Consists of Four Main Types of Learners: Visual, Auditory, Reading and Writing, and Tactile/Kinesthetic (touch)

What We Can Do to Improve Learning:
The fundamental truth is that when a student is unable to get what they need to learn efficiently, factors such as “learning curves” – which may actually be skewing the evidence that students are struggling to learn the content, need to be implemented (1, 3). Instead of masking student learning difficulties with curves and extra-credit, we can take a few simple steps during lesson-planning, or prior to teaching new content, to gauge what methods will result in the best natural overall retention and comprehension by students (4, 9). Some of methods with evidence include (2, 9):

  • Concept Maps – Students Breakdown the Structure or Organization of a Concept
  • Concept Inventories – Short Answer Questions Specific to a Concept
  • Self-Assessments – Short Answer/Multiple Choice Questions
  • Inquiry-Based Projects – Students Investigate Concept in a Hands-On Project

All in all, by combining both previously established teaching methodologies with some of these newer, simple methods of gauging your students’ baseline knowledge and making the necessary adjustments to teaching methods to fit the needs of a given student population or class, you may find that a significant portion of the difficulties that can occur with students and learning such as – poor comprehension, retention, and engagement, can be eliminated (4, 9) .
