基于线上线下融合及翻转课堂的化工原理实验教学改革探索

Exploration on Teaching Reform of Chemical Engineering Principles Experiment Based on Online-Offline Integration and Flipped Classroom

摘要: 文章针对化工原理实验教学传统模式中存在的学生学习兴趣不佳、课前预习不足、设备陈旧及评价体系单一等问题，探索了线上线下融合与翻转课堂的教学改革路径。以过滤实验为试点，构建了课前线上学习及仿真训练、课中以学生为主体分组讲解、课后思考总结的教学流程，有效强化了预习效果，使学生实现从被动操作到主动讲解的转变。并建立涵盖课前、课中、课后的多元化评价体系，重点考核学生的操作规范性、问题解决能力及创新思维。该模式有效降低学生操作失误率，提升学生的主动思考与工程实践能力，为培养创新型工程人才提供更优化的教学范式。

Abstract: This paper addresses issues in the traditional teaching model for chemical engineering principle experiments, such as low student engagement, insufficient pre-class preparation, outdated equipment, and a monolithic evaluation system. It explores a reformed teaching path integrating online-offline blended learning with the flipped classroom approach. Using the filtration experiment as a pilot case, a teaching process was constructed featuring pre-class online learning and simulation training, student-centered group presentations during class, and post-class reflection and summarization. This effectively strengthened preparation outcomes and facilitated students’ transition from passive operation to active explanation. Furthermore, a diversified assessment system covering pre-class, in-class, and post-class stages was established, focusing on evaluating students’ operational compliance, problem-solving skills, and innovative thinking. This model significantly reduced operational errors, enhanced students’ proactive thinking and engineering practice capabilities, offering an optimized teaching paradigm for cultivating innovative engineering talent.
