如何在追求数学教学创新的同时,提高教学实效,发展学生的数学思维能力,值得研讨。笔者认为,计算课中教学创新与实效不是对立的,而是和谐统一的,在创新中落实实效,在实效中体现创新,创新是方法与手段,实效是归宿与目的。一、情境设置,设疑、激趣是重点,有效是核心计算课的情境设置,有些教师特别注重实效,新课伊始就在黑板上抄几个计算题进行复习巩固,学生计算出正确结果,然后随机教学新课。也有些教师太注重创新,呈现主题图,让学生充分发 How to pursue the teaching innovation of mathematics at the same time, improve the effectiveness of teaching, develop students’ mathematical thinking ability, it is worth discussing. The author believes that the calculation of teaching innovation and effectiveness of the lesson is not opposites, but a harmonious unity, to implement effective in innovation, in the actual effect of innovation, innovation is the method and means, effectiveness is the destination and purpose. First, set the situation, set the suspect, the focus is interesting, the core is the effective calculation of the situation settings, some teachers pay special attention to effectiveness, the new lesson at the beginning of the blackboard copy a few calculations to review consolidation, students calculate the correct result, Then random teaching new lesson. Some teachers are too focused on innovation, showing the theme map, so that students fully hair
