笔者参加这次四川省小学教育教学改革共同体的数学组研讨活动,来自不同地区的几位教师执教的几节口算研究课,给我留下了很深的印象。在反思教学的得失时,听课的老师们普遍感觉到,对口算算理重视不够是此次教学研究课中存在的共通性问题。笔者认为,这个问题也是目前口算教学中值得注意的问题。重视学生口算能力的培养,不能忽视口算算理的教学。 The author participated in the mathematics group seminar of the primary education reform community in Sichuan Province. Several research sessions taught by several teachers from different regions left a deep impression on me. In retrospecting the pros and cons of teaching, the lecturers generally felt that the lack of emphasis on mathematical calculation was a common problem in the teaching and research course. In my opinion, this issue is also a noteworthy issue in oral arithmetic. Emphasis on students’ ability to train, can not ignore the teaching of arithmetic.
