Using case studies and build projects as authentic assessments in cornerstone courses

Abstract

Final year, undergraduate engineering students should be exposed to authentic practices that resemble industry to prepare the students for the field. Given that engineering involves design and implementation, final courses should expose students to both through authentic assessments. Case studies, design and build projects, and open-ended final exams were implemented in three, fourth-year cornerstone engineering courses in mechanical, and sustainable and renewable energy engineering. The effects of these changes differed between case study based projects and build projects. Case study based projects resulted in higher project performance and better exam performance than build projects. The improved performance is indicative of better knowledge transfer and a result of increased opportunities for discussion and collaboration between students. These results are consistent with the Ashford-Rowe model for authentic assessments; however, students were divided on the benefits of the authentic assessments. Students were more resistant to the build projects, as reported through the teaching evaluations, because of the increased work load and scheduling required for build projects. This study recommends that cornerstone courses implement case study or paper design projects and open-ended, case study-based final exams to achieve authentic assessments. The use of build design projects for cornerstone courses is not recommended.
