The Great Student Disengagement

With excitement and anticipation for a “return to normal,” faculty, staff and administrators were especially excited to launch Spring semester 2022.  People were vaccinated, students would be attending class with their peers on campus, and extracurricular activities would return to campus. However, it was soon discovered that a return to campus would not mean a return to “normal.”

In addition to the period of “great resignation” and “great retirement,” we soon discovered that a return to campus could be described as the “great student disengagement.”  Faculty observed concerning student behaviors that impacted academic success. Students on our campus have been vocal about their desire to remain at home and on MS TEAMS/ZOOM©. Classroom sessions were required to shift and were often a mixed modality (high flex) as students and faculty underwent COVID protocols that required remote attendance. In a curriculum in which all sessions are mandatory (approximately 20 hours each week in a flipped environment), students requested far more absences in the spring semester than ever before. Even when students were physically present in class, blatant disengagement was observed by faculty.  Attempts to appeal to students’ sense of responsibility and professionalism had little impact in changing behavior.

In attending the Chairs of Physiology meeting at Experimental Biology (EB), student disengagement was an impactful topic of discussion. Somewhat surprisingly, it quickly became apparent that the environment on our campus was somewhat ubiquitous across all institutions of higher education represented in the room that day. Although we shared similar observations, few potential solutions were offered.

Serendipitously, on the final day of EB meetings, the Chronicle of Higher Education published an article by Beth McMurtrie titled “A Stunning Level of Student Disconnection.”  The article shared insight gained from faculty interviews representing a wide range of institutions:  community colleges, large public universities, small private colleges, and some highly selective institutions. Ms. McMurtrie shared stories of faculty who described how students’ brains are “shutting off” and limiting their ability to recall information. The article reports that far fewer students show up to class, those who do attend often avoid speaking, and many students openly admit that they do not prepare for class or complete assignments. Faculty commonly described students as defeated, exhausted, and overwhelmed.

Although specific causes of the “great student disengagement” have not been substantiated, many believe it is the after-math of the pandemic. It seems plausible that the learning environment became more individualized and flexible with fluid deadlines and greater accommodations during the pandemic. Thus, a return to normal expectations has been difficult.

It also seems reasonable that amid the more pressing issues of life (deaths within families, financial struggles, spread of disease), students are reporting high levels of stress, anxiety and general decline in mental health. Perhaps being absent or disengaging while in class (being on cell phones/computers, frequently leaving the room) are simply avoidance mechanisms that allow the student to cope.

Although post pandemic conditions have brought student disengagement to our awareness, some faculty have seen this coming for years.  In a 2020 Perspectives on Medical Education article by Sara Lamb et al. titled “Learning from failure: how eliminating required attendance sparked the beginning of a medical school transformation,” the authors reported low attendance rates, at times as low as 10%, which they attempted to fix with a mandatory attendance policy.  However, over the next six years, student dissatisfaction rose due to the inflexible and seemingly patronizing perception of the policy. This led students to strategize ways to subvert the policies while administration spent significant time attempting to enforce them.  To address the situation, the school transitioned away from required to “encouraged” and “expected” for learning activities.  This yielded both positive and negative results, including but not limited to: increased attendance to non-recorded activities which students deemed beneficial to their learning; reduced attendance to activities that were routinely recorded and posted leading to increased faculty discouragement; reduced administrative burden and tension; and increased student failure rate and feelings of isolation and loneliness.  The authors go on to describe efforts to mitigate the negative outcomes including empowering faculty with student engagement data, and training in active learning pedagogies to enhance student engagement.

As the definitions and root causes of student disengagement pre-date COVID and are somewhat ambiguous, finding effective solutions will be difficult. Perhaps the rapid evolution of teaching and learning brought about by COVID now dictates an evolution of the academic experience and the rise of scholarly projects to address both causes and solutions.

Suggestions on solving the disengagement crisis were published by Tobias Wilson-Bates and a host of contributing authors in the Chronicle of Higher Education dated May 11, 2022. Although we will leave it up to the reader to learn more by directly accessing the article, a list of topics is helpful to recognize the variety of approaches:

  1. Make Authentic Human Connections
  2. Respect Priorities
  3. Provide Hope
  4. Require Student Engagement
  5. Acknowledge that Students are Struggling
  6. Fight Against Burnout

Although we rely on faculty to address student disengagement, it is also useful to consider the stressful environment of faculty. In addition to experiencing the same COVID conditions that students experience, faculty are being asked to continue to provide up-to-date content, utilize engaging teaching modalities, become skillful small group facilitators, as well as advise, coach and provide career counseling.  It is perhaps not surprising that faculty may also feel stressed, isolated, and burned out, surmising that nothing they do makes much difference – opting instead to remain hopeful that students will bounce back.

Regardless of the learning environment on your campus, it is safe to say that now is the time to come together as faculty, students and administrators to discuss the best path forward. Collectively we can work together to set solutions into motion and gather evidence for our effectiveness. It is time to leverage our shared experiences and lessons learned over the past several years of transitioning away from and back into face-to-face classroom instruction. Such reflection and study will support teaching and learning as we all seek to find a “new normal” that meets the needs of students, faculty, and administration alike.

The Olympics, sex, and gender in the physiology classroom

Are there sex based difference in athletic performance before puberty?

In the past few years most state legislatures have considered laws stating that only members of the female sex can participate in girl’s and women’s sports (37 states in 2021 alone), and as of April 20, 2022 fifteen states have adopted such legislation (1). There have also been several well publicized instances of transwomen competing for championships in women’s sports (for example see 2, 3, 4). The International Olympic Committee, the NCAA, and other sports governing bodies have also recently revised their policies regarding the inclusion of transwomen in women’s sports (5, 6).  All of this has resulted in students in my exercise physiology classes commonly asking questions about sex-based differences in sports performance and the inclusion of transwomen in women’s sports.

In a previous PECOP Blog (7) I briefly summarized the sex-based advantages men have in athletic performance in adults, and the research evaluating the effects of testosterone suppression and cross sex hormone use on factors that influence athletic performance. In this PECOP Blog, I will briefly summarize the sex based prepubertal differences in athletic performance and touch on puberty blockers.

A 2012 report from the CDC indicated there were no differences between 6–11-year-old boys and girls in performance on physical fitness tests (8).  Many sports leagues for pre-pubertal children are not separated by sex since the focus is developing basic sports skills rather than competition (9). Furthermore, some scholars have stated that there are no differences in athletic performance between boys and girls prior to the onset of puberty, and that it is only the increased testosterone secretion during puberty that causes males to outperform females in athletic competition (10, 11).

On the other hand, evaluations of fitness testing in children as young as 3 years old shows that boys perform better than girls of the same age on tests of muscular strength, muscular endurance, and aerobic fitness (12-17).  For example, Tomkinson et al. (17) observed that at age 9 boys are running an average of 3.2% faster than girls of the same age during the last stage of a 20 m shuttle run (Figure 1).  In a separate evaluation Tomkinson et al. (16) reported that at age 9 boys have a bent arm hang time that is an average of 48.1% longer than girls of the same age (Figure 2).

Furthermore, youth records from USA Track & Field (18) in the 8-and-under age group and in the 9-10-years-old age group (who can reasonably be assumed to be pre-pubertal) show that boys outperform girls in all events (Table 1).  The smallest difference in track and field records between boys and girls is 0.94% in the 8-and-under 100 m run, with the largest difference being 38.42% in the 8-and-under javelin throw.  We recently analyzed top 10 data for national performance from Athletic.net in 100 m, 200 m, 400 m, 800 m, 1500 m, and 1600 m running events for children in the 7-8 and 9–10 year-old age groups for the years 2019-2021 and found that across all events 7-8-year-old boys were 4.4 ± 1.9% faster than girls, and 9-10-year-old boys were 5.4 ± 1.8% faster than girls (figure 3; not yet published data).  Youth records from USA swimming also show that in 19 out of 23 events the national records for 10 and under boys are faster than girls by an average of 1.72% (19).  It is important to note that in competition the difference between first and second place often comes down to as little as 0.02% difference in speed (Data to be presented at the 2022 ACSM Annual Meeting).

There is no question that the differences in running performance between prepubertal boys and girls is less than the 10-13% difference in running performance observed between post-pubertal boys and girls, and between adult men and women (10, 11, 20).  And there is no question that the large increases in circulating testosterone experienced by boys during puberty is responsible for most of the differences in athletic performance between post-pubertal boys and girls, and between adult men and women (21).  But the existence of differences in athletic performance between prepubertal boys and girls is well demonstrated (12-19).  Juxtaposing the statements of no pre-pubertal athletic differences between boys and girls (8, 10, 11) and the evidence demonstrating that there are pre-pubertal athletic differences between boys and girls (12-19) can facilitate an interesting discussion about data collection, sample size, data analysis, and other factors that may contribute to these contradictory findings.

When explaining the biological causes of the prepubertal athletic advantages in boys, a good starting point is to discuss the differences in growth and development between boys and girls and to explain the processes of sex determination and sex differentiation (22).  Sex determination occurs at conception with the conferral of sex chromosomes.  Six weeks later, sex differentiation begins to become apparent and during the remainder of development the gonads and genitalia acquire male or female characteristics.  During sexual differentiation, the presence of the SRY gene on the Y chromosome along with androgen exposure and anti-Müllerian hormone cause the internal and external genitalia to follow the male developmental pathway. In the absence of the SRY gene on the Y chromosome, lack of androgen exposure, and lack of anti-Müllerian hormone the female developmental pathway occurs. Of course these few brief sentences fail to cover the myriad of complex interactions of genes, primordial stem cells, and hormones that regulate sex development, and the possible differences and disorders that can occur. But it is remarkable that with all of the possible missteps that can happen during sexual differentiation and development, sex can be accurately and easily identified at birth 99.83% of the time (23).

Further substantiating the important role of sex in growth and development are the World Health Organization fetal growth charts (24), which indicate small but meaningful sex-based differences with male fetuses being consistently larger than female fetuses.  Similarly, substantiating the important role of sex in growth and development, the Centers for Disease Control and Prevention have different growth charts for boys and girls from birth through adolescence with boys having consistently higher values for body mass and body height (25).

With an eye towards physical fitness and athletic performance, starting at birth and continuing throughout youth girls have more body fat and less fat-free mass than boys. For example, Davis et al. (26) in an evaluation of 602 infants reported that at birth and age 5 months, infant boys have larger total body mass, body length, and fat-free mass while having lower percent body fat than infant girls. In an evaluation of 20 boys and 20 girls ages 3-8 years old, matched for age, height, and body weight Taylor et al. (27) reported that the boys had less body fat, lower percent body fat, and a higher bone free lean body mass than the girls, such that the girls’ fat mass was 52% higher than the boys, while the bone-free lean tissue mass was 9% lower. In an evaluation of 376 prepubertal [Tanner Stage 1] boys and girls, Taylor et al. (28) observed that the boys had ~22% more lean mass, and ~13% less body fat (when expressed as percent of total body mass) than did the girls. In a review of 22 peer reviewed publications on the topic, Staiano and Katzmarzyk (29) concluded that girls have more total body fat than boys throughout childhood and adolescence.  It is a tenet of exercise science that having more lean body mass provides athletic advantages, so it is reasonable to conclude that having more lean body mass contributes to the prepubertal sex-based male athletic advantages.

It is worth noting that serum testosterone concentrations in boys are higher for the first 5 months after birth than in girls (30). Testosterone concentrations are then similar between boys and girls until the onset of puberty, when testosterone concentrations increase 10-20-fold in boys.  Given the well know anabolic and androgenic effects of testosterone, the higher testosterone levels in newborn boys likely contributes to the sex related differences in body size and composition in newborns.  It is unknown how much the lingering sex-linked differences in body size, body composition, physical fitness, and athletic performance are due lasting effects of the higher testosterone levels in newborns, and how much the differences are due to Y chromosome or other sex-linked effects.

Strongly suggesting that sex linked differences in physical fitness and athletic performance in children before puberty are due to biological factors, Eiberg et al. (13) measured body composition, VO2max, and physical activity in 366 Danish boys and 332 Danish girls between the ages of 6 and 7 years old.  Their observations indicated that absolute VO2max was 11% higher in boys than girls, while relative to body mass the boys’ VO2max was still 8% higher than the girls.  Accelerometry based measurements of physical activity indicated that when boys and girls regularly participated in the same amount and intensity of physical activity, the boys had higher measured physical fitness than the girls.  When the findings of Eiberg (13) are taken collectively with the findings of large scale school based physical fitness testing in children that also shows pre-pubertal boys outperforming girls in measurements of aerobic fitness, muscular strength, and muscular endurance (12, 14-17), the youth records from USA Track & Field (18) showing that pre-pubertal boys outperform girls in all events, and the 10 and under records from USA Swimming showing that boys outperform girls in 19 out of 23 events (19), there exists strong evidence that there are differences in physical fitness and athletic performance between boys and girls before puberty.

And finally, this discussion arising from laws stating that only members of the female sex can participate in girl’s and women’s sports can lead to questions about the effects of puberty blockers on physical fitness and athletic performance in prepubertal children.  Puberty blockers are correctly known as gonadotropin-releasing hormone agonists (GnRHa), which disrupt the normal pattern of secretion of as gonadotropin-releasing hormone causing the pituitary gland to stop producing follicle-stimulating hormone and luteinizing hormone. Unfortunately, there is minimal research on the effects of puberty blockers on factors that influence physical fitness and athletic performance.

To the best of my knowledge, there is no research on the effects of puberty blockers on muscle strength, running speed, or other measures of athletic performance.  Indeed, Klaver et al. (31) is the only published research that I am aware of that has evaluated the use of puberty blockers on any athletic performance related factor, and this is only on body composition. Klaver et al. (31) demonstrated that the use of puberty blockers in Tanner stage 2-3 teenagers increased body fat and decreased lean body mass in transgirls, but the use of puberty blockers did not eliminate the differences in body composition between transgirls and comparable female teenagers. Roberts and Carswell (32), concluded that there is no published research that sufficiently characterizes the impact of puberty blockers on growth or final adult height.  Thus, the effect of prescribing puberty blockers to a male child before the onset of puberty on the physical components of athletic performance is almost entirely unknown. This becomes a great point in a discussion to remind students of the ever-evolving nature of science.  Any further discussion on this topic becomes speculation or can be removed from the realm of physiology and into metaphysical discussions of what is or is not fair.  Such metaphysical discussions can be fascinating, and also heated, so caution is advisable when proceeding outside of the realm of physiology in a physiology classroom.

In summary, there is strong evidence that even before puberty there are sex-based differences in physical fitness and athletic performance with boys running faster, jumping farther and higher, and demonstrating greater muscle strength than girls of the same age.  These pre-pubertal sex based differences are smaller than the differences in post pubertal teens and adults, but the differences are likely meaningful in terms of competition.  There is currently insufficient evidence to determine what effects puberty blockers have on physical fitness and athletic performance in children.

Looking back and moving forward. The importance of reflective assessment in physiology education.

At the end of the 1986 movie Platoon, the protagonist (Chris Taylor, played by Charlie Sheen) provides a very moving monologue that starts “I think now, looking back, we did not fight the enemy, we fought ourselves. The enemy was in us. The war is over for me now, but it will always be there, the rest of my days.”

When Platoon was first released in theaters I was in high school.  I was enthralled with Platoon, and it has held a very special place in my memories ever since.  The ending monologue has echoed through my mind at the end of almost every semester that I have been a faculty member (albeit with a few changes. No insult or mocking of the movie is intended, this is simply my effort to take a powerful cinematic scene and apply it to my personal situation).  My end of semester monologue goes something like this “I think now, looking, back, I did not teach the students but I taught myself. The student was within me.  The semester is over for me now, but it will always be there, the rest of my days.”  And with that, I begin reflective assessment of my teaching.

For many educators, assessment is a dirty word and a necessary evil.  Hall and Hord (1) reported that faulty experience anxiety about assessment because of a lack of understanding of the process or importance of assessment.  Faculty may also disdain participating in assessment due to concerns about accountability, or due to concerns about accreditation negatively impacting their careers (2). Often, faculty also view assessment reports as things that need to be prepared and submitted to meet requirements imposed on faculty from an administrative office within their institution, or some outside accrediting agency, but think that assessment reports are not really pertinent to the day-to-day work of education (3).  To help overcome hesitancy to fully engage in the assessment process Bahous and Nabhani (4) recommend that institutions hire a full-time assessment officer to work one-on-one with faculty.  All of these are relevant to the formal process of assessment and submitting data and reports to meet institutional or organizational requirements.  When done the right way, these assessment reports can be valuable tools in education.  But what I want to discuss in this blog post is a more informal form of assessment that I think all educators should do, and probably already do, which is reflective assessment.

Students and faculty alike perceive Physiology as a very challenging academic subject (5, 6).  The concepts are difficult, and there is a lot of terminology.  Our understanding of physiology is continually expanding, but yet students often still need to have a firm concept of the basic fundamentals before moving on to more complex and in-depth information.  Physiology is often taught in a system by system approach, yet the systems do not operate independently of one another so at times it may feel like the cart is put before the horse in regards to helping students to understand physiological processes. All of these issues with the difficulty of teaching physiology make reflective assessment an important part of teaching.

Quite simply, no matter how well we taught a class or a concept, as educators we may be able to teach better the next time (7, 8).  Perhaps we can tweak an assignment to make it better fit our needs.  Or perhaps we can provide a new resource to our students, like an appropriate instructional video or a scholarly article. Or maybe it’s time to select a new textbook.  Or maybe we have seen something in Advances in Physiology Education or on the PECOP Blog that we would like to incorporate into our teaching practice.  Whatever the reason, reflective assessment provides an opportunity for us to ask ourselves two very simple, but very important questions about our teaching:

  1. What went well in this class, and what didn’t go as well as planned?
  2. What improvements are we willing to make to this course to improve student learning?

The first question is important for identifying strengths and weaknesses in our courses.  We can ponder what went well, and ask why it went well.  Has it gone well each semester? Or did it go well because of changes we made in our teaching?  Or did it go well because of other changes, such as a change in prerequisite courses?

As we ponder what didn’t go as planned, we can also contemplate why things didn’t go as planned.  I think anyone who has taught through the COVID pandemic can identify lots of unforeseen and unusual disruptions to our courses.  But we can also use reflective assessment to identify ongoing problems that deserve some attention.  Or we can identify problems that have previously not been problems, and make a note to monitor these issues in future courses.

The second question, about what changes are we willing to make, is also extremely important.  Sometimes a problem may be outside of our control such as course scheduling, who teaches the prerequisite course, or other issues.  But if the identified problem is something we can control, such as the timing of the exams, or the exam format, or laboratory exercises, then we need to decide if the problem arises from something we are willing to change and then decide how and what to change.  Can the problem be addressed through the acquisition of new instrumentation?  Can the problem be addressed by changing textbooks?  Some of the problems may be easy to solve, while others might be more difficult.  Some problems might require funding, and so funding sources will need to be identified.  But this is where reflective assessment can really help us to prioritize changes to our teaching.

I ask myself these questions throughout the semester as I grade tests and assignments, but in the midst of a semester there is often not time to really ponder and make changes to my classes.  During the semester I keep a teaching diary to make note of the thoughts that come to me throughout the semester. Then, after final grades are submitted and before the next semester begins there is more time to read through the teaching diary and to reflect and ponder about my teaching.  Often, in this less pressured time between semesters, by reviewing my teaching diary I can take a step back to reflect on problems during the semester and determine if this has been an ongoing issue in my classes or an isolated issue limited to only this one semester.  I often find that what seemed like a problem in the middle of the semester has resolved itself by the end of the semester.

Of course there are many other questions that can be asked as part of reflective assessment (7, 8), and any question can lead to numerous follow up questions.  But I think these two questions (1. What went well in this class, and what didn’t go as well as planned? 2.  What improvements are we willing to make to this course to improve student learning?) form the cornerstone of reflective assessment.  And reflective assessment can then lead to a career long endeavor to engage in action research to improve our teaching skills.

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?
Mari K. Hopper, PhD
Associate Dean for Biomedical Science

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.
