《数学新课程标准》指出:“教师应激发学生学习的积极性,向学生提供充分从事教学活动的机会,帮助他们在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能,数学思想和方法,获得广泛的数学活动经验。”课堂讨论作为“自主探索、合作交流”的一种重要方式,对激发学生学习兴趣,拓展学生思维能力以及培养学生的主体意识有着重要的作用。教师作为课堂教学的组织者,该如何组织课堂讨论,使之发挥积极作用,让数学课堂更有效呢? The new mathematics curriculum standard states: “Teachers should stimulate students’ enthusiasm in learning and provide students with opportunities to fully engage in teaching activities so as to help them truly understand and master basic mathematical knowledge and skills during their own exploration and cooperation and exchange, Mathematical ideas and methods and gain extensive experience in math activities. ”Classroom discussion as an important way of“ exploring independently, collaborating and communicating ”has important implications for stimulating students’ interest in learning, developing students’ thinking ability and cultivating students’ subjective consciousness Role. Teachers as classroom organizers, how to organize class discussions, make it play an active role in making mathematical classroom more effective?
