课堂教学改革启动以来,我在课堂教学中实践生本理念,使课堂教学的气氛得到了活跃,也切实提高了数学课堂教学效率,让学生一步步成长起来.但是在小组合作学习的过程中也出现了一些问题,下面结合自己的教学实践谈一谈自己的认识.一、关于学习小组的分工科学分组,合理分工是小组合作学习顺利开展,发挥小组学习功能的前提.例如推导圆的面积公式的教学过程中,是通过转化法进行的. Since the beginning of the classroom teaching reform, I have practiced the concept of student-centered teaching in class teaching, which has made the atmosphere of class teaching active. It has also effectively improved the efficiency of mathematics classroom teaching so that students can grow up step by step. However, There are some problems, the following combination of their own teaching practice to talk about their own understanding.A study group on the division of division of science, reasonable division of labor is the group to carry out cooperative learning smoothly, to play a group of learning functions.For example, The teaching process, through the conversion method.
