目前,技工学校普遍存在着机械加工学习条件不足的现象,特别是铸造、锻造、磨削、刨削、等方面,致使这门实践性很强专业课,大多在教室里以说教的形式进行。很多学生反映《机械制造工艺基础》课的基本知识难懂、技能知识难学、机床结构难记,对这门课程的学习兴趣不大。我在长期的教学实践过程中,认为启发式教学法是一种行之 At present, mechanization schools generally lack the learning conditions of machining, especially in casting, forging, grinding, planing, and other aspects, resulting in a very practical and specialized course, mostly in the form of preaching in the classroom. Many students reflect the basic knowledge of “basic mechanics of manufacturing process” difficult to understand the basic knowledge of skills difficult to learn, difficult to remember the structure of the machine, the course of interest in learning little. In the long process of teaching practice, I think heuristic teaching method is one way
