新课标实施以来,合作学习的教学模式越来越受教师的青睐和学生的欢迎,是新时期推广素质教育,适应新高考的一种有效教学模式。在高中数学课堂开展合作学习过程中,针对存在的各种问题,尝试探索一种有效的合作学习模式。以“古典概型”这一课为例,通过活动片段的形式阐述在数学课堂上高效开展合作学习的模式。 Since the implementation of the new curriculum standard, the teaching mode of cooperative learning has become more and more popular with teachers and students. It is an effective teaching mode to promote quality education and adapt to the new college entrance examination in the new era. In the process of cooperative learning in high school mathematics classroom, we try to explore an effective model of cooperative learning for all kinds of problems. Taking the lesson “Classical Probability” as an example, this paper expounds the mode of carrying out cooperative learning efficiently in mathematics classroom through the activity fragments.
