装配图是反映产品的构造、性能、工作原理和使用维修要求的重要技术文件。工科院校的学生学习《机械制图》的最终目的是能够看懂一张装配图,能够从装配图中看懂设计者的设计思想,主要零件的结构形状,各零件间的连接关系、传动路线、装配关系,最后,还要能够看懂工作原理,包括一些技术要求。装配图的第一次课是为我们后面学员如何看懂装配图打基础的,是一次非常重要的基础知识课。但通常基础知识多是一些原则性的论述,似流水帐,且缺乏逻辑关系,如果教员在上课时照本宣科,无疑会使学员觉得罗嗦,激不起学员的学习兴趣,常常是老师讲得“口干舌燥”,学员听得“一塌糊涂”。为了避免此种现象的发生,提高学员的学习兴趣,适应现代素质教育,为此,我在装配图初次课中引入了研讨式教学法。所谓研讨式教学法是指建立在教员引导的基础上,以学员自主研究和课堂讨论的方式开展教学活动的一种教学方法。具体做法如下:一、理清思路,抓住重点教员要上好一堂课,关键是要备好课,而备好课的关键又是对教学内容的熟练掌握、合理安排,要做到思路清晰、重点突出、主次分明。一堂没有重点内容,甚至本末倒置,绝对不可能是精彩纷呈、吸引学生 Assembly drawings reflect the product structure, performance, working principle and the use of maintenance requirements of the important technical documents. The ultimate goal of students in engineering colleges and universities to learn “Mechanical Drawing” is to be able to understand an assembly drawing, understand the designer’s design idea, the structure and shape of the main parts, the connection between the parts, the transmission line , Assembly relationships, and finally, to understand the working principle, including some technical requirements. The first lesson of assembly drawing is a very important basic course for how to understand the assembly diagram for the students behind us. But usually the basic knowledge is more principled discourse, like running account, and the lack of a logical relationship, if the teacher in the class according to the propaganda, will undoubtedly make students feel wordy, excite students interest in learning, often the teacher said “ Dry mouth ”, students heard“ a mess. ” In order to avoid this kind of phenomenon, improve student’s study interest and adapt to modern quality education, for this reason, I introduced the seminar teaching method in the initial assembly course. The so-called seminar-based teaching method is based on the guidance of teachers, based on the independent study of students and classroom discussions to carry out teaching activities of a teaching method. The specific practices are as follows: First, to clear up the train of thought, to seize the key teachers to have a good class, the key is to prepare a good lesson, and the key to preparing a lesson is to master the teaching content and reasonable arrangements to be clear thinking , Focused, primary and secondary clear. There is no key content, even the cart before the horse, it is absolutely impossible brilliant, attractive students
