This paper describes the combination of problem-based learning (PBL) and simulation tools in the chemical engineering unit operation laboratory course, focusing on heat transfer concepts using a shell-and-tube heat exchanger experiment. This approach has significantly enhanced student learning outcomes by bridging theory with practice, fostering a deeper understanding of engineering concepts, and cultivating vital skills like problem-solving, critical thinking, and teamwork. The study provides valuable insights into innovative pedagogical methods for improving engineering education.
