In engineering education, integrating practical skills with theoretical knowledge is essential for developing competent professionals. This study investigates the benefits of linking Computer Aided Manufacturing and Metal Forming Technologies courses to enhance project-based learning. The primary objective was to assess whether this integration could improve student retention and effectiveness in PBL environments. Using a mixed-methods approach, data were collected from postgraduate mechanical engineering students through surveys, project evaluations, and performance metrics. The integration of these courses resulted in increased student engagement and retention, as well as enhanced quality and innovation in student projects. The findings support the hypothesis that interdisciplinary course integration fosters a more collaborative and engaging learning experience, bridging the gap between theoretical knowledge and practical application. These results align with educational research advocating for experiential and applied learning models, suggesting that such approaches improve retention rates and problem-solving skills, ultimately preparing students more effectively for professional challenges.
