所谓认知冲突,是指学生在学习过程中已有的认知结构与新的学习任务之间出现了矛盾与冲突,这种新旧知识之间的差距使学习者认知心理产生了失衡。学习者都有保持认知平衡的心理倾向,因此教学中如果适时地创设一些认知冲突,使学生的求知心理出现暂时失衡,就会驱动学生去跨越冲突障碍,努力恢复失衡的心理,进而促进学生产生探索新任务的欲望,使主动学习有效发生。那么,数学教学中如何有效创设认知冲突呢?从数学学习的主要流程视角来
The so-called cognitive conflict refers to the contradiction and conflict between the existing cognitive structure and the new learning task in the process of learning. The gap between new and old knowledge makes the cognitive psychology of learners have an imbalance. If learners have the cognitive tendency to maintain a cognitive balance, if the teaching is to create some cognitive conflicts in a timely manner so that students’ psychological distress temporarily appears, it will drive students to overcome the obstacles and strive to restore the unbalanced psychology so as to promote Students have the desire to explore new tasks so that active learning takes place effectively. So, how to create cognitive conflicts effectively in mathematics teaching? From the perspective of the main flow of mathematical learning
