智能教育背景下谈中职数学课堂教学的守正与创新——以探究空间图形的位置关系为例

立体几何这块内容历来是整个中职数学的难点,不仅仅知识点抽象难懂,性质定理错综复杂,更在于非常考验学生的空间想象和逻辑推理能力,而这两个能力正是中职学生的所欠缺的,同时传统的教学方式往往只是单纯观察实物模型和三维动态图,学生参与度不高,效果欠佳,由此也成为了中职数学教师的教学痛点。基于此,我们尝试了针对此课程《探究空间图形的位置关系》的课程框架和内容的重构、教学模式和手段的创新、数学知识和专业技能的结合,力求在智能教育背景下找到中职数学课堂教学的守正与创新的平衡点。

The content of solid geometry has always been a difficult point of mathematics in secondary vocational schools.It is not only difficult to understand abstract knowledge points and complicated property theorems,but also very difficult to test students’spatial imagination and logical reasoning ability,at the same time,the traditional teaching method is often only to observe the physical model,and three-dimensional Dynamic Diagram,the student participation is not high,the effect is not good,which has also become the secondary vocational mathematics teacher’s teaching,pain point.Based on this,we try to explore the course framework of spatial graphic position relation,and the reconstruction of the content,the innovation of teaching mode and means,and the combination of mathematics knowledge and professional skills,under the background of ability education,find the balance point between keeping right and innovation in mathematics classroom teaching in secondary vocational schools.
