《喷油嘴清洗》教学设计
一、教学任务
能运用形体分析法和线面分析法绘制切割类组合体的三视图。
二、教学分析
1、分析教材
《机械制图》是各职业学校工科类专业的一门技术基础课,也是车工,钳工等工种必考的应知考试科目,因此机械制图是机械、机电专业的一门重要课程。教材是省教育厅职成教教研室项目教学法组编的项目四的任务5，结合实际生产绘制零件的三视图。
2、分析学生
对于初中毕业的职业学校学生,机械制图是一门完全陌生的课程,他们没有接触过生产实际,缺乏应有的理论基础,特别由于传统的教材体系和教学方法影响,部分职业学校学生将机械制图课视为畏途,深感枯燥乏味,对教师课堂的理论讲授表现出消极学****甚至厌学的现象。因此,必须改革职业学校的机械制图的教学,以调动学生的学****积极性,激发学生的求知欲。
三、教学目标
1、知识目标：绘制和识读组合体的形体分析法与线面分析法
2、能力目标：绘制切割类组合体的三视图
3、情感目标：进上步培养和提高空间想象能力、空间思维能力和创新思维能力
四、教学重点与难点
1、掌握绘制组合体三视图的方法与步骤
2、利用形体分析法与线面分析法来绘制组合体的三视图
五、教学方法
自主探究、小组讨论演示并交流、多媒体演示。
六、教学内容
一、前置作业：
1、用橡皮泥切制长方体，你能切出多少种不同的类型？
