Project-based learning: Student performance and perceptions in a food industry engineering degree course

The project-based learning (PBL) methodology was applied in a Food Technology course during the third year of a Food Industry Engineering degree at the University of Extremadura. The purpose of the research was to assess the effectiveness of PBL in this specific teaching field, evaluate the utility of rubrics, and determine the level of student satisfaction. A total of 22 students were tasked with participating in a group activity where they had to formulate, design, prepare, and present a food product to their peers and teacher. The students produced multiple deliverables and received feedback from the teachers. They also completed a final report and an oral presentation. The project was evaluated by teachers, peers (peer evaluation), and through self-evaluation using rubrics. A satisfaction survey and an analysis of strengths, weaknesses, opportunities, and threats were conducted after the completion of the PBL activity. The main findings indicated that PBL and rubrics were effective teaching and evaluation methodologies, respectively, enabling students to achieve scores above 8. Teacher evaluations were higher than the self-assessments, which were close to peer evaluations, indicating a high level of commitment on the part of students. Effective communication skills need improvement. Students viewed the activity positively, as it helped them comprehend the subject matter and proved valuable for improving teamwork, autonomy, and overall learning. In conclusion, PBL resulted in an engaging and effective learning experience that enhanced the understanding of food processing content and fostered the development of the skills and competencies necessary for a professional food engineer.
