信息化社会的高速推进以及素质教育的深入发展,给职业高中数学学科教学提出了新的要求。数学反应客观世界的数量关系,研究空间几何体的结构、形状、大小以及相互位置关系的抽象特征,以及客观世界的空间形式,因而学生需要研究图形的性质,必须具有空间想象能力。空间想象能力的培养也贯穿于中等职业学校数学学习过程中,要求我们在教学实践中要加强学生空间想象能力的培养。
The rapid development of information society and the further development of quality education have brought new requirements to the teaching of mathematics in vocational high schools. Mathematical responses to the quantitative relationship between the objective world, the study of spatial geometry of the structure, shape, size and the abstract characteristics of mutual positional relationship, as well as the objective world of spatial form, so students need to study the nature of graphics must have spatial imagination. The cultivation of spatial imagination also runs through the process of mathematics learning in secondary vocational schools, requiring us to strengthen the cultivation of students’ spatial imagination in teaching practice.
