Under the key competencies

the instructional design of the section "Thermal stability of ideal mixing reactor" in the textbook of polymerization reaction engineering is taken as an example to explore the educational value in the teaching process of engineering. Through the analysis and discussion of the principle of thermal stability and the analysis of the examples of thermal stability in industry

the students are guided to understand the concept of principle with the scientific thinking of engineering. Driven by probing into problems

inquiry-based learning is carried out to cultivate students' awareness of engineering problems and practical application ability

and to implement the cultivation and development the key competencies of undergraduates in the course of teaching.
