Concept Maps in Immunology: A Metacognitive Tool to Promote Collaborative and Meaningful Learning Among Undergraduate Medical Students

Introduction: Concept maps are graphical representations of knowledge that connect concepts, ideas, and relationships. The present study aims at assessing the perception of medical students in utilization of concept maps as a tool to foster their lifelong learning skills in immunology.

Methods: The current study was approved by Institutional Ethics and Review Committee. Third-year undergraduate (MD3) medical students of the academic year 2021-22 were sensitized about the concept map study and included after obtaining their informed consent. The students worked in teams to find answers and link the different words or phrases of the concept maps. At the end of the immunology course, students' perception on concept map-based learning strategy was assessed. A pre-designed, self-administered questionnaire, pre-validated by subject experts for relevance and feasibility, was used for the study. The questionnaire included some quantitative questions assessed by using 3-point Likert Scale and an open-ended question to receive students' comments on concept map-based learning strategy. The responses were collected and analyzed using SPSS version 22. Descriptive statistics was used for the quantitative variables, tabulated as numbers and percentages while the qualitative data was analyzed by thematic analysis. The quantitative data results were prioritized but supported by students' comments on open ended question.

Results: Out of 133 eligible participants, 109 students who volunteered and completed the study were included. Majority of our participants (>80%) welcomed the concept map-based learning strategy. Almost 4 out of 5 expressed that concept maps are interesting and enjoyable, encourage active participation, peer discussion, and enhance critical thinking and problem-solving skills. More than 80% of the students agreed that concept maps promoted deep understanding of the topic and lifelong learning. Nearly 3 out of 4 students suggested including concept maps in many immunology topics in future. Majority of students penned down positive comments indicating concept map tool facilitates metacognitive skills.

Conclusion: From the study, it can be concluded that concept maps are effective active learning strategies to improve the metacognitive domain of medical students in immunology course, thus assisting them to become better lifelong learners.
