学生多元化角色培养:化工热力学融合式教学模式改革与实践

Multi-role Cultivation of Undergraduates: Reform and Practice of Syncretic Teaching Mode for Chemical Engineering Thermodynamics

基于化工热力学课程教学改革现状,文章探索了基于工程案例分析的融合式教学模式的应用。以化工热力学中能量平衡和火用平衡计算的知识点为例,教师选取历届全国大学生化工设计竞赛优秀作品中的工程案例,通过课堂理论知识讲授、课后工艺流程分析及措施优化,以小组研讨答辩的形式实施教学改革,引导学生从学习者、设计者等角度深入思考,进而培养学生的多元化角色。教学实践表明,这种基于工程案例分析的融合式教学模式对提高课程教学效果和培养复合型卓越工程人才大有裨益。

In view of the current status of teaching reform in chemical engineering thermodynamics, this paper explored the application of syncretic teaching mode. By taking the knowledge points of energy-and exergy-balance calculations as an example, we selected some outstanding works from National Undergraduate Chemical Design Competition as the engineering cases to conduct the reform. Its implementation was realized through the procedure of classroom lecture of theoretical knowledge, and analysis of the processes after class and optimization of measures, and group discussion and defense. We guided the students to think deeply from perspectives of learners and designers so that promote their multi-role cultivation. The results showed that such syncretic teaching mode is of great benefit to the improvement of course-teaching effect and cultivation of excellent inter-disciplinary engineering talents.
