Integrating Theory and Practice in Engineering Education: A Cross-Curricular and Problem-Based Methodology

Engineering education often struggles to connect academic content with the real-world skills demanded by industry. Despite the inclusion of teamwork, collaborative learning, and leadership training in engineering curricula, many graduates remain unprepared to deal with complex and professional challenges. This study presents a cross-curricular, practice-oriented methodology designed to strengthen the integration of theoretical knowledge and professional competencies among engineering students. The method has been implemented in the degree in Industrial Design and Product Development Engineering at the University of Cádiz. Students engaged in a realistic design task—developing an outdoor clothesline system—requiring the application of content from Materials Science, Structural Analysis, and Computer-Aided Design. Digital tools such as MILAGE LEARN+ (for gamified content review) and MindMeister (for concept mapping) have been integrated to promote autonomous learning and interdisciplinary thinking. The methodology has also been designed to improve transversal skills such as initiative, communication, and teamwork through collaborative and student-led project development. The approach has been evaluated through pre- and post-intervention surveys, informal feedback, and internship outcomes. The results showed a 40% reduction in students reporting difficulty retaining theoretical content (from 78% to 38%) and a 29% increase in self-perceived autonomous learning. The proportion of students feeling unprepared for professional environments dropped from 73% to 34%. Those experiencing anxiety when facing real-world problems has been reduced from 92% to 57%. Students have also reported greater motivation and a clearer understanding of the practical relevance of the academic content. These findings suggest that structured interdisciplinary challenges, when supported by blended learning tools and authentic design problems, can significantly improve student readiness for professional practice. The proposed methodology offers a replicable and adaptable model for other engineering programs seeking to modernize their curricula and foster transferable and real-world skills.
