Integrating challenge-based learning and design thinking in a course of reaction engines for aerospace.

This article focuses on integrating challenge-based learning (CBL) and design thinking into an aerospace engineering course on reaction engines to address the growing need for sustainable propulsion systems. It outlines a series of interactive sessions designed to engage students in understanding environmental impacts, ideating sustainable solutions, conducting research, and analyzing real-world case studies, thereby fostering critical thinking, collaboration, and problem-solving skills. Student feedback collected through semi-structured interviews indicated a positive reception to this pedagogical approach, highlighting its relevance and interactivity while also noting challenges related to pacing, balancing technical depth, and providing clearer guidance. The study emphasizes the importance of iterative curriculum development informed by ongoing student input to better prepare aerospace engineers for future environmental and industry challenges.
