小学数学教学中,学生通过归纳、类比、联想等方法探究出的猜想,往往感性知识较多、理性知识较少,认知不够深刻,还停留在比较肤浅的层面,只有通过组织学生自主探究验证自己的猜想,才能将他们的思维慢慢地引向深入。教师不仅要给予学生充分的时间和空间去探究和验证他们自己的猜想,引导学生在探索的过程中用具体事例证明“猜想”的合理性、正确性,还要培养学生数学验证的能力,学会验证的基本方法,让学生在数 Primary mathematics teaching, students through induction, analogy, association and other methods to explore the conjecture, tend to have more perceptual knowledge, less rational knowledge, cognitive depth is not enough, but also remain in the more superficial level, only through the organization of students to explore the verification Their own guess, in order to slowly lead their thinking deeper. Teachers should not only give students enough time and space to explore and verify their own conjectures, and guide students to prove the rationality and correctness of “conjecture ” in the process of exploration, and to train students’ ability of mathematical verification , Learn the basic method of verification, let the students in the number
