随着新一轮课程改革的实施,在“人人学有价值的数学”“不同的人在数学上得到不同的发展”“为人的发展而教”等教学基本理念的指导下,小学数学教学的内容、方式都将发生显著的变化,动手实践、自主探索与合作交流应该成为学生学习数学的重要方式。但课程改革是一个需要不断实践与探索的渐进过程,教材内容的更新总是滞后于教学理念的更新。而且在新教材逐年推出的较长一段时间内,新旧教材将同时并存。原有教材能否上出新理念,如何上出新理念,已经成为一个亟须思考与研究的实际问题。本文拟通过“圆锥的认识”(浙教版小学数学六年制第十二册)一课先后两次教学中一个教学片段的对比分析,谈谈我们的思考和认识。
With the implementation of the new round of curriculum reform, under the guidance of the basic concepts of teaching such as “Everyone learns valuable mathematics”, “Different people get different development in mathematics” and “Teaching for the development of human beings”, elementary mathematics teaching Content, way will have significant changes, hands-on practice, independent exploration and cooperation and exchange should become an important way for students to learn mathematics. However, the curriculum reform is a gradual process which requires constant practice and exploration. The updating of teaching materials always lags behind the updating of teaching concepts. And in the new textbook introduced year by year for a long period of time, the old and new textbooks will coexist at the same time. Whether the original textbook can come up with new ideas and how to come up with new ideas has become a real problem that needs to be thought and studied urgently. This article intends to pass the “conical understanding” (Zhejiao Primary School mathematics six years of the twelfth volume) a lesson has two teaching in a comparative analysis of teaching fragments to talk about our thinking and understanding.
