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

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

 

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

 

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

 

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

 

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

 

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

 

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

 

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

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

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

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

 

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

 

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

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