众所周知,大家生活在三维空间,而立体几何就是研究生活中物体形状、大小与位置关系的学科。对五年制高职生而言,学习生活中会接触很多这样的空间模型,比如:机械专业的零部件、应用化工专业的各种化工仪表制图等,没有扎实的空间思维和感观是难以学习的。对五年制高职生来说,立体几何教学一直是难点。笔者在教授本部分内容时,形成了采用合适教育理论、应材施教、交流与鼓励、引入其他评价制度等方式,笔者发现学生比以往更容易接受立体几何,从心理也不再抗拒立体几何。本文从四个具体的角度,浅谈五年制高职立体几何教学的一些心得,不当之处请同行批评指正。
As we all know, we live in three-dimensional space, and three-dimensional geometry is to study the object of life in the shape, size and location of the discipline. For five-year vocational college students, they will come into contact with a lot of space models in their study life. For example, mechanical specialty parts and chemical chemical mechanical charting, which are applied to chemical industry, are not difficult to think and feel without a solid space educational. For five-year vocational college students, three-dimensional geometry teaching has been difficult. When I was teaching this part, I formed the theory of appropriate education, applied teaching, communication and encouragement, and introduced other evaluation systems. The author found that students are more likely to accept the three-dimensional geometry than before and no longer resist stereoscopic geometry . This article from four specific perspectives, talk about the five-year vocational three-dimensional geometry teaching some experience, inappropriate please peer criticism.
