Challenges in implementing cross-disciplinary design experiments in a large scale introductory physics class; a case study

These were developed in response to student feedback indicating that overly structured experiments limit their grasp of the abstract concepts of electricity and magnetism. Consequently, each of the four in-class experiments has an open-ended, design component, exploring a practical application of the concepts. In addition, these experiments were built upon an "active learning" structure, whereby students interact with each other and with online materials during class. They were integrated into a class of >700 students, with 8 sections total (~90 per section), with pre- and post-experiment assignments to support and reinforce the material covered. After each experiment, the students were surveyed to determine their self-assessment to gauge their understanding of the purpose of the experiment and assess whether sufficient time was allocated to the experiment. At the end of the term, the students were also surveyed to compare their experience with both the traditionally highly structured experiments and the design experiments conducted during the same semester. Results revealed that though the design experiments were more enjoyable for the students, they perceived the traditional experiments as more relevant to the lecture material. Possible reasons why the students saw less connection to the lecture material might be attributed to the novelty of these experiments and some structural problems in deploying them on such a large scale. While problems associated with the adoption of new pedagogical approaches are not surprising, it is important to carefully assess the outcomes and reflect on how to address the shortcomings for the next iteration.by Pushpaleela Prabakar.S.M. in Engineering and ManagementS.M.S.M.inEngineeringandManagement Massachusetts Institute of Technology, System Design and Management ProgramS.M.
