Abstract

Grounded in interdisciplinary efforts to improve student learning and professional development in the domain of bioengineering, this paper describes the design, use, and evaluation of an alternative form of instruction and assessment in a yearlong senior biomedical engineering (BME) design course at Vanderbilt University. Specifically, members of the Vanderbilt-Northwestern-Texas-Harvard/MIT Engineering Research Center (VaNTH ERC) Assessment and Evaluation Team and the instructor of a yearlong capstone BME design course developed and implemented ways in which concept mapping would (1) promote active student engagement with course material and (2) serve as a framework for helping students integrate new knowledge into existing knowledge. Consistent with our previous work in this area, quantitative analyses of concept maps created by students (n = 51) at the beginning and end of the fall semester showed significant growth in students’ conceptual knowledge of the design process. However, early and late maps did not differ in terms of associations among concepts. These findings suggest that while students are acquiring knowledge about design, they do not have a deep understanding of relationships among elements of the design process. As an indication of the extent to which concept maps actively engage students with course material, we are comparing this year’s class (i.e., Innovative group) and the previous year’s class which received traditional instruction (i.e., Traditional group), in terms of student final exam scores, course evaluations, learning strategy use, intrinsic motivation to learn, and perceptions of the course experience. Findings are discussed in terms of their implications for theoretical understanding of the structure of knowledge, and instructor efforts to enhance students’ conceptual understanding of the design process.
