合作学习是新课程所提倡的一种较为先进的学习方法,这种学习方法要求教师要创造一个宽松、和谐、愉悦的课堂学习环境,引导学生进行主动学习,增强数学学习的效率。在数学小组合作学习摸索与实践的过程中,有时要不拘形式,打破常规;有时在某些方面还应引起我们的高度关注,在变革中前进,才能使数学小组合作学习更具实效性。我们在数学教学过程中,为了能在短短的20分钟内达到真正的预习目的,教师必须提前做好充分的准备:一是整理、印制好教学案及早发到每一个学生手里;二是在组长的组织和监督下,以读书和整 Cooperative learning is a more advanced learning method advocated by the new curriculum. This kind of learning method requires teachers to create a relaxed, harmonious and pleasant classroom learning environment and guide students to take the initiative to learn and enhance the efficiency of mathematical learning. In the course of collaborative study and practice of maths group, it sometimes takes informality to break the routine. Sometimes, in some aspects, it should also attract our attention and advance in the changes so that the math team can learn more effectively. In the teaching of mathematics, in order to achieve the real purpose of learning in just 20 minutes, teachers must make adequate preparations in advance: first, organize and print the teaching case as early as possible to each student’s hand; Under the leadership of the organization and supervision, to study and the whole
