Enhancing Student Learning Outcomes through Brief Cold Working and Annealing Interventions in Materials and Manufacturing Selection in Design Course

This study examines the impact of a brief (10-15 minute) annealing and cold working classroom intervention on student learning outcomes in the Materials and Manufacturing Selection in Design course.The intervention, designed to fit seamlessly into the course schedule, uses active learning strategies to help students describe the microstructural evolution and the corresponding effects on material properties during cold working, annealing, and phase transformations.Through short demonstrations and problem-solving activities, students observe how these processes influence material characteristics, enhancing both their conceptual understanding and ability to apply this knowledge.Results show that these brief, focused interventions significantly improve student engagement, retention, and learning outcomes in complex technical topics.This work extends prior research in materials science education 1 , demonstrating the effectiveness of short, active learning strategies in reinforcing key learning objectives.
