Abstract: In response to the learning characteristics of undergraduate chemical engineering students, the teaching team has systematically incorporated engineering cases, core equipment, and research methodologies into the instructional process. By establishing organic connections and synthesizing key knowledge points to address practical chemical engineering challenges, this approach aims to cultivate students' ability to comprehensively apply acquired knowledge in solving real-world problems. The methodology fosters an integrated teaching philosophy that harmoniously combines engineering cases, core equipment, and research methods into a “trinity” framework. Teaching practice has demonstrated the effectiveness of this “trinity” approach, significantly enhancing students' capacity to apply theoretical knowledge to practical engineering problem-solving.
