Many people do learning communities (see MAT and CPD LC's) to try improve retention in classes. However, the LC between PHY 121 and MAT 221 has been about trying to improve student understanding of the concepts of physics and calculus and how they fit together. Retention and success in these coures have been fine which is reason for focus on understanding rather than retention. From the attached file it can be seen that on the Force Concept Inventory the LC students did better than traditional class even though they had less math preparation for the course. Thus, the LC improves understanding and allows students to get through faster without hurting their learning. Will used what areas still need improvement from FCI for focus in spring LC.
