基本几何体教学在机械制图中是非常重要的内容,常见的几何体有圆柱、圆锥、棱柱、正方体等,这些常见的几何体在数学课程中又有另外的定义,叫“空间几何体”。职业学校的教学培养目标是非常明确的,主要以服务专业应用、技能为目的,但在中职高二数学教材内容上,还不能有效地围绕这个目标和原则来开展教学工作。主要论述在中职的数学课程如何结合机械制图教学中基本几何体的教学,让数学知识与机械制图教学紧紧联系在一起,发挥它们彼此的价值和作用,同时也让学生更好地把数学知识应用到机械专业中,培养学生应用数学知识服务于专业的技能,让专业知识的学习达到更好的效果。 Basic geometry teaching is very important in mechanical drawing. Common geometric bodies are cylinders, cones, prisms, cubes, etc. These common geometric bodies have another definition in mathematics course called “spatial geometry”. The goal of teaching and training of vocational schools is very clear. The main purpose is to serve professional applications and skills. However, in the content of mathematics teaching materials for secondary vocational schools, we can not effectively carry out teaching work around this goal and principle. Mainly discusses how the mathematics curriculum in secondary vocational education combined with the teaching of basic geometry in mechanical drawing teaching, so that mathematical knowledge and mechanical drawing teaching closely linked to play their mutual value and role, but also to enable students to better mathematical knowledge Applied to the mechanical profession, training students to apply mathematical knowledge to professional skills, so that professional learning to achieve better results.
