Adaptation of Physical Chemistry Course in COVID-19 Period: Reflections on Peer Instruction and Team-Based Learning

Abstract

The COVID-19 pandemic has highlighted the importance of incorporating distance learning for long periods. However, few studies have addressed strategies to overcome the limitations caused by the lockdown. In this study, we report an active learning experience on the topic of chemical kinetics, using two flipped class approaches, team-based learning (TBL) and peer instruction (PI). These methodologies have been adapted to remote learning for undergraduate students from chemistry and engineering courses. Materials (video class and bibliography) were made available, as part of the preparation for the activities. TBL and PI groups performed the active learning activity (ALA), which consisted of graphic problems about kinetics of simple order reactions. An individual post-test was applied to assess the students’ performance 2 weeks after ALA. In addition, students answered a questionnaire addressing their perceptions of ALA. The methodologies did not show significant differences in students’ performances. Both enabled the acquisition of soft skills. Participants of both methodologies agree that traditional in-person classes could be partially or totally replaced by ALA, corresponding to 59.6% and 9.8%, respectively. PI participants presented a better perception of their learning than TBL students did. Thus, the use of technological tools in a recontextualized way, such as the adaptation of TBL and PI to a virtual environment, proved to be very promising for the Physical Chemistry course and an opportunity to implement a methodology that places students at the center of the teaching–learning process. The active learning activities proposed in this study can integrate distance learning, even after the pandemic context.
