数学是一门发展历史悠久的学科,其素养的培养对任何学生而言是十分重要的。小学生因为知识经验少,空间想象能力又比较差,对数学中几何图形的认知存在困难。如果只靠教师一味单纯地讲解,很难获取良好的教学效果。教师作为人类心灵的工程师,担任着太阳底下最光辉的职业,应当与学生积极地进行互动,设计合乎学生心理的教学方案和策略,调动学生学习的积极性,让学生认识几何图形并掌握所学到的几何知识。
Mathematics is a long-established subject of development and the cultivation of its qualities is of great importance to any student. Because of their lack of knowledge, primary school students have poor imagination and difficult to recognize geometry in mathematics. If you rely on teachers simply to explain, it is difficult to obtain a good teaching effect. As an engineer of the human mind, teachers are the most brilliant professions in the sun. They should actively interact with the students, design teaching plans and tactics in line with the students ’psychology, mobilize students’ enthusiasm in learning, enable students to understand geometry and master what they have learned The geometric knowledge.
