Developing activities and assessments is where the flipped classroom shines, as it transforms in-person time into opportunities for active learning and evaluation of student understanding. Consider what activities will engage students and reinforce your objectives: Will you use polls to check understanding of inflammation signs, quizzes to assess pre-class learning, or case-based discussions to apply concepts to a patient scenario? Assessments should align with your objectives— for instance, a TBL application exercise might ask students to diagnose a sepsis case using complement knowledge. Activities should encourage collaboration and critical thinking, such as small group debates or problem-solving tasks. Ensure assessments provide feedback to both students and faculty, helping to gauge learning progress. The following resources will guide you in designing activities and assessments that promote active learning and measure outcomes effectively.
