随着新课程改革的不断深化,很多新型的教学方式被探索应用,合作学习是其中非常重要的一项方式。很多情况下,小学数学教师可以想到合作学习可以提高学习的团结协作能力,却忽视了思辨能力的培养,本文主要探讨了如何在合作学习的模式下培养学生的思辨能力。一、发起思辨,创设数理探讨情境数学的学习不仅需要积极开动脑筋,还需要组织学生进行讨论、争辩,只有这样才能理清思路,建立清晰的数理概念。教师要根据教学内容和学生的接受能力, With the deepening of the new curriculum reform, many new teaching methods have been explored and applied. Cooperative learning is a very important one of them. In many cases, primary school mathematics teachers can think of cooperative learning can improve the learning ability of unity and cooperation, but neglected the cultivation of speculative ability. This article mainly discusses how to cultivate students’ speculative ability under the mode of cooperative learning. First, to initiate speculation and create a mathematical discussion Situational mathematics learning not only need to actively start their brains, but also need to organize students to discuss and argue, the only way to sort out the way to establish a clear mathematical concept. Teachers should be based on teaching content and student acceptance,
