Active Learning Using a Two Pass Strategy in a Calculus Based Introductory Physics Course

For the Fall 2018 semester, we modified our active learning strategy to use a two pass approach over blocks of material. For the first block, simple, formative problems were assigned covering basic kinematics through conservation of energy. Another pass through the same material then used substantively more difficult problems. A second block of material covering momentum, rotation, statics, gravity, and fluid mechanics was treated in a similar manner. The force concept inventory was administered as a pre-test the first day of class and as a post test at the end of the second block.  We report here the matched pair normalized gain, effect size, and normalized change for the group.
