小学数学教材选择的内容非常贴近学生的生活实际,有利于学生体验与理解、思考与探索。有许多定理、定律、公式等鉴于学生的年龄特点和知识层次,往往不需要经过推理与证明,仅通过适当的举例验证,凭学生的直觉与经验来判断、形成结论。因此,教学中一些结论的得出,学生常常能“很快”接受,而当教师尝试引导学生“证明”这些结论时,学生往往不感兴趣,他们认为这些结论显而易见,不需要证明。有些老师们也认为,简单地呈现结论并运用好结 The selection of primary school mathematics textbooks is very close to the actual life of students, is conducive to student experience and understanding, thinking and exploration. There are many theorems, laws, formulas, etc. Given the age characteristics and knowledge level of students, they often do not need to be reasoned and proved. Only by proper examples and intuition and experience of students to judge and form conclusions. As a result, some conclusions from the teaching conclude that students are often “too fast” to accept, and that students tend not to be interested when teachers try to guide students to “proof,” and they conclude that these conclusions are obvious and do not require proof . Some teachers also think that simply concluding and applying good results
