数学课堂中的“陷阱”设计,是教师呈现教材重点、突破教学难点的一种策略。在小学数学教学过程中,教师要根据教学的实际需要,创设一些带有悬念或破绽的教学情境,让学生在不知不觉中掉进预设的“陷阱”里。一、设置悬念,为新知学习埋下伏笔教学中教师要善于在学生所认识、所熟悉的教学材料中设置悬念,通过恰当的启发、诱导,改变学生原来固有的认知 The design of “trap” in mathematics classroom is a tactic that the teacher presents the key point of teaching materials and breaks the difficult teaching. In the process of primary school mathematics teaching, teachers should create some teaching situations with suspense or flaws according to the actual needs of teaching, so that students fall into the preset “trap” unknowingly.
