Revisions to a physics lab for life science majors.

This presentation discusses the results of modifications made to a one-credit, stand-alone laboratory course for life science majors. The course, which can be taken alongside or after an algebra-based Newtonian physics course, includes activities on translational, rotational, and harmonic motion. Students are also asked to complete a longer project applying models developed in their earlier labs to a biomechanical system. Recently, the course was updated to emphasize modeling and experimental design, shifting from its previous focus on reinforcing conceptual understanding. We are evaluating the impact of these changes on students' modeling skills and attitudes about the course. Our findings, which highlight the effectiveness of the new course design, will be presented.
