研究生机械故障诊断学实践教学改革探讨

Discussion on Practical Teaching Reform of Mechanical Fault Diagnosis for Postgraduates

在分析机械故障诊断学教学问题的基础上,结合翻转式课堂教学模式,提出"教学-讨论-测试"(TDT)这一实践教学模式。教师根据实践教学内容和班级人数,将学生分为讲解组和其余组,并在教学环节与讨论环节负责全程引导与组织,在测试环节则转变为主持。讲解组采用多种教学方式完成实践教学的讲解,并在教师引导下组织相关专业问题的讨论与思考。通过振动测试实践教学案例分析,可以证明该模式能有效地激发学生的学习积极性与主动性,锻炼学生掌握新知识和新技能的能力,值得在实践教学过程中进一步推广。

Based on the analysis of the problems in the practical teaching process of Mechanical Fault Diagnosis,"Teaching-Discussing-Testing"(TDT)practical teaching mode is proposed in combination with the flipped class teaching mode.Teachers divide students into explanatory group and non-explanatory group according to the content of practical teaching and class size;they are responsible for guiding and organizing the whole process in the teaching and discussion links,while in the testing links they are changed into host.Explanatory group uses a variety of teaching methods to complete practical teaching explanations,and organizes discussion and reflection on relevant professional issues under the guidance of teachers.Through the analysis of practical teaching cases of vibration testing,it can be proved that the model can effectively stimulate students’learning enthusiasm and initiative,and train students’ability to master new knowledge and skills,which is worth further promotion in the process of practical teaching.
