The Impact of Instructional Methods on Critical Thinking: A Comparison of Problem-Based Learning and Conventional Approach in Engineering Education

Recent research reveals a gap in determining the effect of problem-based learning (PBL) on students’ critical thinking ability. Existing evidences from previous research have been equivocal to be deemed conclusive, especially in across multiple educational disciplines. This paper investigates the effect of PBL on students’ critical thinking ability, as compared to conventional approach. The study employed an experimental pretest and posttest with control group design. The participants were 53 undergraduate students in electrical engineering course, who attended Electrical Technology Module (ET101) in their first semester. Participants completed the pretest and posttests of the translated version of the Cornell Critical Thinking Test Specimen set. The results suggested that students’ critical thinking ability in the PBL group had not been significantly different from their counterparts in the conventional approach group. This paper further discusses the implication of problem-based learning in engineering education.
