机械基础是技工学校机械类专业的一门专业基础课,理论和实践的要求高,有着不同于一般文化基础课的特点。由于学生初次步入机械工程领域没有实际经验,对设备结构更不了解,头脑中没有形成空间模型,空间抽象,思维又比较差,所以教师在课堂上仅用语言讲解那些学生从来没见过的设备结构和它的动作过程,学生听得 The mechanical foundation is a specialized basic course for mechanical engineering major in technical school, which has high requirements of theory and practice and has characteristics different from those of general cultural basic course. Because students have no practical experience in the field of mechanical engineering for the first time, they do not know much about the structure of the equipment, they do not form a spatial model in their minds, they are abstract in space, and their thinking is rather poor. Therefore, teachers only use language to explain what students have never seen before Equipment structure and its course of action, students hear
