As a PhD candidate in the Pathobiology and Translational Biosciences program, I am passionate about the intersection of graduate education and rigorous, clinically-relevant research. As such, I served as the teaching assistant for General Pathology (PATHOL 750) in spring 2024. Of the 7 students in this class, most were first- and second-year PhD students in the Pathobiology and Translational Biosciences program.
In my role as TA, one of my primary goals for my students was for them to understand foundational principles of pathophysiology. In addition to being able to visually identify pathologic features in tissue, I wanted them to have a familiarity with the cellular and molecular mechanisms underlying these morphologic changes. However, I also felt deeply invested in encouraging my students to use this knowledge to inform their own graduate research. I believe that a thorough understanding of normal physiology and known mechanisms of disease pathogenesis provides students with a solid starting point for their own research. This is critical in translational research, where our research focuses on understanding disease-causing mechanisms for the development of disease-modifying therapies. By introducing students to examples of disease mechanisms in a variety of fields (e.g. immunopathology, neoplasia, etc.), students develop a baseline familiarity with known disease mechanisms, which can lead to hypothesis generation for their own work. These critical thinking skills are fundamental to graduate students’ education because the intellectual focus shifts from learning information to creating new knowledge.
My experience as a TA for PATHOL 750 helped to clarify my own priorities as both a scientist and an educator. By focusing on these priorities, I am better able to equip my students with the skills and knowledge necessary to meet my goals for them (and their goals for themselves!). Upon reflection, my priorities as an educator can be broadly grouped into two overarching goals: maximizing clarity and promoting a growth mindset.
In my experience, setting clear expectations builds students’ confidence. My dedication to providing my students with clear instructions can be observed through the guidelines I provided for slide descriptions, a recurring homework assignment throughout the semester in which students describe the pathological findings in a piece of tissue featured on their assigned microscope slides. Students were given these instructions prior to the first assignment deadline, along with several examples of excellent work by previous students. The benefit of these detailed instructions and example assignments was made evident by my students' work, in which they emulated these examples to produce high-quality work of their own.
Presenting course content clearly is also extremely important. One way in which course material can be demystified is by presenting the content in a clear, engaging manner. As a TA, I was the primary teacher for our Immunopathology Unit. Because the immune system is so complex, this unit contains a large amount of complicated content. I know it is easy for students' minds to wander when they are inundated with a lot of information without clear direction indicating where they should focus their attention. In preparing slides for this lesson, I made thoughtful choices regarding my use of graphics; I wanted to effectively draw students' attention to the most important information on the slide. I found that by intentionally including duplicate slides with different parts of the image grayed out, it helped students stay engaged as I presented the information. By highlighting "bite-sized" bits of information at a time, students seemed to retain the key concepts I wanted them to remember. Furthermore, repeating the same graphic throughout a lengthy lecture can help to orient the students and clearly put each piece of information into its broader context.
I have also found that holding exam review sessions is very beneficial — even though these sessions were optional, attendance was always high. Students seemed to appreciate one final opportunity to seek clarification regarding both my expectations and content, as it provided a forum for them to ask about the information they were expected to know for the exams and to discuss course material that remained confusing or unclear to them.
One key practice which contributed to the development of a growth mindset for my PATHOL 750 students was the regular discussion of mock scientific questions. Students were prompted with a situation based on a principle of pathogenesis previously discussed in class, which provided them with the tools to develop a rationale for possible explanations for the phenomenon described in the scenario. This encouraged them to think critically and comprehensively about feasible ways to both explain and test their ideas. While these types of questions are challenging, they mirror the types of problems we face in biomedical research. In composing a satisfactory response to these types of questions, it requires the student to connect their existing knowledge about principles in pathophysiology with scenario-specific details, identify the gap in knowledge, form a hypothesis to explain the phenomenon, and propose ways to test their ideas. In my experience, taking an iterative approach to these types of questions based on class discussion effectively emphasizes the importance of continued growth and development, which is an important aspect of scientific research in both academic and industry settings. Encouraging students to shift their mindset toward valuing improvement over perfection helps to build their confidence over time. As students develop this key skill, they provide responses which are more structured, methodical, comprehensive, and deeply based in valid scientific rationale.
Another strategy I used to encourage my students to develop a growth mindset was the manner in which I provided feedback on assignments. For example, when grading weekly slide descriptions, I intentionally did not penalize students heavily for mistakes; instead, I provided detailed feedback with specific, constructive pieces of criticism. In my experience, providing this type of detailed, non-punitive feedback motivates students to improve the quality of their work without excessive focus on the numerical grade. Students were generally very responsive to this type of feedback, as evidenced by the corresponding adjustments they made in subsequent assignments.
Finally, another critical aspect of promoting a growth mindset involves cultivating a classroom environment in which students feel sufficiently comfortable to make mistakes. To this end, I prioritize establishing a collaborative atmosphere which rewards effort and improvement. One method which I have used to cultivate a collaborative atmosphere is to establish early in the semester that cold-calling will be used regularly throughout the course. While students often feel uncomfortable with this at first, the expectation that all students contribute to the collective learning experience quickly makes it easier for students to contribute to class discussions. In addition to cold-calling, using small-group discussion strategies increases students’ comfort with speaking in class, as sharing a small-group discussion with the class is generally less intimidating than taking sole ownership of a response. These strategies foster an environment focused on growth and skill development, which I believe significantly enhances learning at the graduate level.
