A flipped classroom redesign in general chemistry

Abstract

The flipped classroom continues to attract significant attention in higher education. Building upon our recent parallel controlled study of the flipped classroom in a second-term general chemistry course (J. Chem. Educ., 2016, 93, 13–23), here we report on a redesign of the flipped course aimed at scaling up total enrollment while keeping discussion sizes small (i.e., <30 students), and maintaining equivalent contact hour load for faculty and workload for students. To that end, the course format featured lecture contact pushed outside of the classroom in the form of video lectures (mean duration 13 minutes) paired with online homework sets, and three parallel weekly one-hour discussion sections were held in adjoining lab rooms immediately prior to the three-hour laboratory session. As in our previous design, the discussion sections were led by teaching assistants; however, the weekly discussion meeting was shortened from 75 minutes to 50 minutes, and the primary instructor “floated” between the three parallel sessions. Two such sessions were held each week, affording a possible enrollment of 144; initial enrollment was 141, with students self-selecting into the course. We examine student performance in and satisfaction with the course using: (1) a pre-test/post-test design based on the paired questions American Chemical Society (ACS) first-term and second-term exams, (2) data on DFW (D, F, withdrawal) rates, and (3) student evaluations.
