The Effects of Service-Based Learning on Metacognitive Strategies During an Engineering Design Task

Abstract

Service-based learning has become an emerging pedagogical tool for engineering education. Although there is a large body of literature reporting the benefits of service activities, most studies have relied on self-report measures and generalized learning contributions. Our evaluation went beyond self-perceptions by investigating the impact that service-based learning programs had on specific cognitive elements of engineering design. The primary goal of this project was to investigate what effects, if any, service activities had on the engineering design process. Verbal protocols were collected from ten engineering students during an open-ended, model-building design task. The five service students and five non-service students also completed post-task interviews and reflection papers. The students in our sample who had participated in service-based learning activities voiced more metacognitive phrases, demonstrated more accurate task analysis and clearer strategic planning skills, were more skilled at discriminating useful from superfluous information, and had a better understanding of clients' needs and constraints. From our sample, it appears that participation in service-based learning activities enhances the design process of engineering students.
