BOPPPS模型在乙酸乙脂合成项目教学中应用

Application of BOPPPS Model in the Teaching of Ethyl Acetate Synthesis Project

为了提高有机化学实验的教学质量,解决单一线下或者线上实验教学中出现的问题,以乙酸乙酯的合成为例,探索了BOPPPS教学模型在现有的线上线下教学模式中的应用。以六个阶段:导入元素B、学习目标O、预评价阶段P、课堂参与阶段P、后测阶段P和总结阶段S为主线,采用线上教学软件雨课堂、QQ课程群等与线下分组、分段式相结合的教学方法,引导学生自主学习、强化课堂互动和课后评价。实践表明,这种模式能够大大增强学生的学习兴趣,提高学生实践动手能力,培养学生的创新能力。

In order to improve the teaching quality of organic chemistry experiments and solve the problems in a single offline or online experimental teaching,taking the synthesis of ethyl acetate as an example to explore the application of BOPPPS teaching model in the existing mode of online and offline teaching.In six stages:guide elements B,learning target O,pre-evaluation stage,P,P after test stage P and summary stage S as the main line,using online teaching software rain classroom,QQ class and offline grouping and segmented teaching methods to guide students to independent learning,strengthen classroom interaction and afterclass evaluation.Practice shows that this model can greatly enhance students’interest in learning,improve students’practical ability,and cultivate there innovation ability.
