Educational Research and Methods
Project-based learning (PBL) has been widely adopted in engineering education because of its proved effectiveness in improving students’ problem-solving skills, collaboration skills, self-directed learning skills and academic achievement . Moreover, it has been reported that students’ participation in PBL activities could be beneficial for their epistemological development . Nevertheless, it remains unclear how students’ personal epistemology were impacted via PBL.
In this research, we set out to understand the impact of PBL on engineering students’ personal epistemology in the context of Perry's theory, which depicts students’ epistemological development from dualistic thinking to a contextual constructive manner of thinking in four stages, that is, Dualism, Multiplicity, Relativism and Commitment (within Relativism) . In our prior study we provided a profile of engineering students’ epistemological development in the context of Perry’s theory through a quantitative measurement . Built upon our prior findings, we interviewed twenty-one students whose predominant thinking style fell into the higher levels of Perry’s theory (Relativism and Comment). Specifically, we explored the relationships between engineering students’ personal epistemology and their engagement in PBL activities in a qualitative manner.
Our preliminary findings demonstrated a range of different formats of PBL in engineering students’ learning and their respective impact on their personal epistemology. These different formats include capstone design projects, course design projects, research projects, projects in competitive events, and others. The complexity level, the amount of guidance received in the projects and other factors were closely associated to students’ personal epistemology. These preliminary findings suggest the importance of carefully scaffolding the complexity of projects and the incorporation of mentoring process in students’ involvement of engineering projects. We expect outcomes of this research will provide practical suggestions for the implementation of project-based teaching and learning.
