Design and assessment of a project-based learning in a laboratory for integrating knowledge and improving engineering design skills

Abstract

Mechanical Design is a subject usually included in Chemical Engineering Degrees. In this work, we present the application of a project-based learning to the lab in two different engineering degrees, in of one the most time-consuming and difficult subjects of their programs. These two degrees, Mechanical and Chemical engineering degrees, were selected in order to compare the learning outcomes and satisfaction with the activity in the degree more related to mechanical concepts and the Chemical engineering degree. Moreover, to enhance students’ enthusiasm and motivation, these sessions included an innovative manufacturing technology, 3D printing, and digital image correlation (DIC). Before each practical session, the students are encouraged to watch an online video with the fundamental aspects. In order to assess the success of this methodology, after finishing the lab sessions, the students answered a non-formal quantitative survey. The results showed that the proposed project-based learning had the ability to help integrating the knowledge and improve the skills included in the main competences. Although these results are encouraging, there are still parts of the lab activity that should be improve in order to make the activity less time consuming and the most difficult part being easier for the students.
