通过激发学生的思维,丰富其空间想象能力,能将枯燥、复杂的几何知识转化为简易、有趣的空间图形,进而有助于学生更好地理解几何知识,形成自己的解题思路,化解几何难题。文中阐述了如何从培养学生几何基础思维、逻辑思维能力、空间想象能力三方面来激发学生的思维,提高几何的教学质量。 By stimulating students’ thinking and enriching their spatial imagination ability, the knowledge of the boring and complex geometry can be transformed into the simple and interesting spatial graphics, which helps students to understand the geometric knowledge better, form their own problem-solving ideas, resolve the geometry problem. This article elaborates how to inspire students ’thinking and improve the teaching quality of geometry from three aspects: cultivating students’ basic thinking of geometry, logical thinking and spatial imagination.
