BOPPPS理念下有机化学教学设计探索与实践——以卤代烃亲核取代反应机理为例

Exploration and Practice of Organic Chemistry Teaching Design Based on BOPPPS——A case study of nucleophilic substitution reaction mechanism of halogenated hydrocarbon

有机化学作为众多理工科专业的基础课程,其涉及知识面广,难度大。因此,以教师为主体的传统教学方式,难以激发学生的学习兴趣、培养学生的自主学习能力。为达到课程教学目标,有机化学课程教学基于雨课堂及学习通构建混合式教学体系,以BOPPPS教学理念为基础,有效设计并实施“目标为导向,学生为主体”的参与式教学模式。教学设计实施后,对课程教学方法、激发学习兴趣、知识掌握情况、自主学习能力培养等七个方面进行问卷调查。结果显示,学生对教学方法满意的达到98.86%,认为能有效激发学习兴趣的占98.97%,认为能提升自主学习能力的占98.87%,对有机化学知识掌握较为满意的占94.31%,教学成效显著。

Organic chemistry is a basic course for many science and engineering majors,which is characterized by a wide range of knowledge and great difficulty.In addition,the traditional teacher-oriented teaching method is not effective in stimulating students’interest in learning and cultivating students’independent learning ability.In order to achieve the teaching objectives,organic chemistry course teaching is based on Rain Classroom and Learningpass to build a hybrid teaching system,based on the teaching philosophy of BOPPPS,effectively design and implement the"target-oriented,student-centered"participatory teaching mode.After the implementation of the teaching design,a questionnaire survey was conducted on seven aspects of the course including the teaching methods,stimulating learning interest,knowledge mastery and the cultivation of independent learning ability.The results showed that 98.86%of the students are satisfied with the teaching method,98.97%of them considered that it can effectively stimulate their interest in learning,98.87%of them supposed that it can improve their independent learning ability,and 94.31%of them were satisfied with the knowledge mastery of organic chemistry,which have achieved ideal teaching results.
