Abstract: The “Principles of Chemical Engineering” course is a fundamental core subject for students specializing in chemical engineering and related disciplines. It plays a critical role in building their theoretical foundation, engineering competencies, and innovative thinking. To address various challenges in teaching this course, the instructional team has adopted a student-centered, interdisciplinary, and digitally enhanced approach. This strategy integrates cross-disciplinary content, broadens multidimensional teaching resources, implements a four-stage progressive learning model, incorporates project-based problems with AI virtual team members, enriches evaluation criteria, and deepens assessment frameworks to drive instructional innovation. These reforms have effectively increased students' engagement and affinity for the course, strengthened their engineering mindset, and enhanced their innovative capabilities. Ultimately, these improvements elevate the overall teaching quality of the "Principles of Chemical Engineering" course, fostering “quasi-engineers” with strong practical engineering skills and innovative thinking.
