Critical thinking activities in fluid mechanics – A case study for enhanced student learning and performance.

We describe the implementation of Critical Thinking Activities (CTA) designed to encourage 'critical thinking' in an undergraduate engineering Fluid Mechanics course. Critical thinking can be a vague term both difficult to grasp and even more so to measure. Using a longitudinal case study we analyse quantitative and qualitative data collected over three years to explore the overarching question: "how do we know students have thought critically?". We investigate and evaluate the quantitative data that emerged from students undertaking the CTA and the impact of this on their performance. The results indicate that students who performed well in the CTA achieved a final grade for the course of 5 or more (Credit, Distinction or High Distinction). Qualitative data from student feedback demonstrated that the CTA was a significant factor in reinforcing student learning, enabling us to identify areas of misconception and areas in which they could improve. While the study is situated in an engineering context at the University of Queensland, the paper is an exemplar of embedded and sustainable practice, is equally transferable to other disciplinary contexts. • Successful implementation of critical thinking activity (CTA). • CTA used problem-based-learning and reflection through integrated feedback loop. • Three year long studyshows significant impact on student learning • Method used is equally transferable to other disciplines.
