论文部分内容阅读
《热工学》是我校机械设计专业(四年级)的必修课程。我选择了其中的传热学部分(12学时)进行磁带教学试验。这部分内容的特点是理论阐述和公式推导较多,图示不复杂。为了便于分析磁带教学的效果,采取对比试验的方法。随机确定磁带教学组和传统教学组。抽签结果,前者19人,后者18人。磁带教学的具体作法是:把课堂上要讲的内容提前录制在磁带上,同时写出与板书大致相同的讲授提纲;把磁带和提纲发给学生,上课时学生戴上耳机边听磁带边看提纲,教师随堂答疑;每次教学
“Thermotechnics” is a compulsory course in Mechanical Design (4th grade) in our university. I chose one of the heat transfer part (12 hours) tape test. This part of the content is characterized by theoretical elaboration and formula derive more, the diagram is not complicated. In order to facilitate the analysis of the effect of tape teaching, take a comparative test method. Randomly identify tapes and traditional teaching groups. Ballot results, the former 19 people, the latter 18 people. The specific teaching tape is: the content to be taught in the classroom recorded in advance on tape, and at the same time write out the same outline of the outline of the teaching plan; tapes and syllabus issued to students, class students wear headphones to listen to tape while watching Syllabus, teachers Q & A; each teaching
