发酵与分离工程实验教学改革的探索与实践

Exploration and practice of the teaching reform of fermentation and separation experiment

发酵与分离工程实验教学中存在大型生产实验无法开展、实验演示操作学生看不清楚的问题。为了解决这些教学问题,一方面通过加强实验课程资源建设,建立了生产工艺虚拟仿真实验、实验操作与讲解视频等教学资源。另一方面,改进实验教学方法,将教师讲授式教学改为翻转课堂式教学。教改后学生预习效果、实验操作标准程度、实验理解和综合运用能力明显提高。因此,通过制作虚拟仿真、实验操作视频等教学资源供学生自学,结合翻转课堂式教学能够明显提高学生的学习效果,是一种值得推广的实验教学方法。

There are some problems in the teaching of fermentation and separation engineering experiment,like large-scale fermentation experiments cannot be carried out,and students cannot see clearly during the experiment operation show.In order to solve these problems,we constructed the experimental curriculum,such as virtual experiments of fermentation technology,experimental operations and explanation videos on one hand.On the other hand,we improved the experimental teaching method,changing the teacher-centered mode to the flipped classroom teaching.After the teaching reform,the students'preview effect,experimental operation level,the understanding and comprehensive application of experiment have been improved significantly.Therefore,combining the teaching resources with the flipped classroom can significantly improve the learning effect of experimental teaching,and the method is worthy of promotion.
