随着数学新课程改革的不断推进,数学课堂逐渐变得生动起来了,学习内容的开放、灵活、生活化,使学生的学习有了更多的“自由度”。教师中似乎存在一个不成文的规定:能上得热热闹闹的课就是符合新课程理念的好课,然而,在这些“热闹”的背后,我们冷静地思考一下会不难发现,许多教师都忽略了一个至关重要的问题,即对数学练习设计的研究。在许多新授上有些教师为了注重培养学生动手操作能力或自主探索精神,一堂课下来,只推导了一个计算公式或一个解决问题的办法,连基本的练习都没有几条;还有些教师前半堂课采用新
With the continuous advancement of the new mathematics curriculum reform, the mathematics classroom has gradually become vivid, and the content of learning is open, flexible and life-oriented, giving students more “degrees of freedom” in their studies. There seems to be an unwritten rule in teachers: a class that can be bustling is a good lesson that fits the new curriculum concept. However, behind these “bustles”, we calmly think hard to find out that many Teachers have overlooked a crucial issue, the study of mathematical practice design. In many new professions, some teachers in order to focus on cultivating students’ hands-on ability or self-exploration spirit, a lesson down, only derived a formula or a solution to the problem, even the basic exercises are not few; some teachers The new class
