P544: On-line lectures: a strategy to liberate class time for active learning
Increasing class size, demands on student time and the desire to implement “high impact practices” in the classroom have all brought about recent changes in the approach to teaching 300-level biochemistry classes at St. Olaf College. One innovation that satisfies both student expectations for lecture and the instructor’s desire to present material quickly is the “On-line Lecture”, a video podcast that allows students to receive a digital lecture outside of class, focus their textbook reading and review as frequently as they wish. By moving lecture outside of class time, alternative activities can be implemented in-class with the goal of improving student’s problem solving skills, fostering independence and promoting confidence in a supportive environment. Analysis of in-class exams both pre and post “flip” showed no change in the overall grades earned but the exams themselves were more difficult with respect to the number of questions asked at the higher Bloom levels. Details on preparing and using the On-Line Lectures and examples of in-class activities will also be presented.
