Challenge-based instruction: the VaNTH biomechanics learning modules

This paper presents the methodology and results of teaching an engineering course using a challenge-based approach. The challenges consisted of eight biomechanics learning modules developed as part of the VaNTH NSF educational coalition. The pedagogical framework for these modules is based on the widely publicized book "How People Learn" (HPL). The HPL teaching framework presents the learning material as a series of challenges that are posed through a "Legacy Cycle." The VaNTH biomechanics modules were presented in an undergraduate mechanical engineering course titled "Biomechanics of Human Movement" in Fall 2004. The class (N=18) was divided into three-member teams. All challenges were performed by the teams using computer-based homework assignments that were supplied by the instructor on a CD. Pre-tests, post-tests, and affect rankings were administered for each modular topic. The students were also surveyed on the learning effectiveness of the various components of each module. At the end of the semester, the students completed a biomechanics topics matrix that mapped the challenges to the various class topics. Results of this classroom experience and data gathering are presented in this paper
