基于三视图演示器发展空间观念

Developing Space Concept Based on Three-view Demonstrator

空间观念是逻辑思维能力的外在表现,培养和发展小学生的空间观念是当下小学数学教学的核心问题,力求在教学中发展学生能够适应终身发展和社会发展所必备的品格和能力。研究以三视图为例,依托三视图演示器教学具,采用"击鼓传花"的课堂活动形式,实现教学操作的全员化,旨在动手操作的过程中,培养学生的空间观念,发展数学素养。

Spatial concept is the outside performance of logical thinking ability. Training and development of the students＇ spatial concepts are the core problem of the elementary school mathematics teaching. In teaching we make every effort to de-velop students＇ essential character and ability, which need to adapt to lifelong development and social development. With three view drawing as an example, based on three view drawing demonstrator, adopting Chain of Responsibility forms in class ac-tivities, realize the goal of all staff participation. In operation process, cultivate students＇ spatial concepts; develop students＇ core competencies of mathematics.
