贵刊(《中小学数学小学版》)近年来多次刊登了我国著名小学数学教学法专家邱学华教授关于是否需要背熟“20以内加法”问题的讨论文章,邱教授在加法口诀教学上积累了大量的研究数据和经验,现在又发起成立加法口诀研究共同体,笔者学习后结合自己近30年的小学数学教学实践经验,觉得邱先生的观点十分准确和重要,我本人也十分赞同他的观点,并认为在小学数学教学中重视加法口诀的教学具有科学心理理论的依据,具有十分重要的教育价值。具体地说我们可以从以下五个方面进行分析:第一,小学生的记忆力是其智力的重要组成部 In recent years, you have published many articles about Professor Qiu Xuehua, a well-known primary school mathematics pedagogy expert, on the issue of whether you need to memorize and “add within 20” questions. Professor Qiu taught in the teaching of addition formulas Accumulated a large amount of research data and experience, and now it has initiated the establishment of an additional formula research community. After learning the author’s experience in teaching mathematics in elementary schools for nearly 30 years, I think Mr. Qiu’s view is very accurate and important. I personally agree with him Point of view, and that the teaching of emphasis in the primary school mathematics teaching additive formula has the basis of scientific theory of mind, has a very important educational value. Specifically, we can analyze from the following five aspects: First, the memory of primary school students is an important part of their intelligence
