翻转课堂教学模式在“机械结构设计与装配”课程教学中的探索及应用

The exploration and application of flipped classroom teaching mode in the course of"mechanical structure design and assembly"

“机械结构设计与装配”是高职院校机械类专业的一门基础课,包括理论力学、材料力学、机械原理及机械零件等知识体系,内容广且存在一定难度.高职院校学生基础较薄弱,上课易走神,参与度低,课堂效果差.为提高“机械结构设计与装配”课程的教学效果,本文引入翻转课堂教学模式,以四川化工职业技术学院汽修专业为例,针对该专业2018级甲、乙、丙3个平行班应用差异化教学模式,甲班采用传统讲授法,乙、丙班采用翻转课堂(丙班分组学习,乙班未分组).结果 表明,对于“机械结构设计与装配”课程,以学习小组形式进行翻转课堂可明显提升平均分、及格率和优等生比例,提高教学效果.

"Mechanical Structure Design and Assembly"is a basic course for mechanical majors in higher vocational colleges.It includes a theoretical system of theoretical mechanics,material mechanics,mechanical principles,and mechanical parts.It is extensive and difficult.The vocational college students'base is relatively weak,easy to get distracted in class,low participation,and poor class effect.In order to improve the teaching effect of the course of"Mechanical Structure Design and Assembly",this paper introduces the flipped classroom teaching mode.Taking the automobile repair major of Sichuan Vocational College of Chemical Technology as an example,different teaching modes are applied to the 2018 class A,class B and class C parallel classes.Class a adopts traditional teaching method,and class B and class C adopt flipped classroom(Class C studies in groups,class B does not).The results of final course,average score and pass rate of class A,class B and class C(Class C is significantly higher than Class A and class B,class A is higher than class B),and the proportion of each score segment(the proportion of excellent students in class C is significantly higher than Class A and class B).The results show that for the course of"Mechanical Structure Design and Assembly",flipped classroom in the form of learning group can significantly improve the average score,pass rate and the proportion of excellent students,improving the teaching effect.
