Too Many B cells, When Food Fights Back, and Hacking T cells: The effective use of case studies to teach methods in an undergraduate Immunology course.

Abstract

Abstract The rapidly changing nature of immunology makes it a challenging course for both undergraduate students and faculty. A teaching approach that incorporates essential immunological techniques and an introduction to the primary literature helps undergraduates navigate the discipline and remain current. Case studies are an effective active learning approach that provide real world examples to engage undergraduates and an opportunity for hands on problem solving, data analysis, and critical thinking as students must consider outcomes and consequences. Although case studies that explore clinical connections already exist for undergraduates, they do not include key techniques or provide experience working with the primary literature. We have developed several case studies to help undergraduate immunology students understand and analyze data involving: flow cytometry, CRISPR/Cas, CAR T cells, and ELISAs. The case studies 1) introduce students to techniques and methods they may not have access to in their laboratory courses due to the lack of appropriate instruments or the cost of reagents, 2) build on difficult concepts covered in the course, and 3) incorporate figures from papers that challenge students to apply what they have learned. Assessment of student learning includes in-class quizzes and small group responses to data analysis questions, the use of “clickers”/personal response system, and related exam questions. Students self-report that the case studies are a highly effective teaching method that allow them to both reinforce their understanding of the course material and apply it to practical problems.
