让数学真正好玩起来,相信这是我们每个老师的心愿。每个老师都期待在自己的课堂上,学生能积极的思考,主动地建构知识,设计“认知冲突”是一种有效的策略。尊重学生认知,不回避甚至深入挖掘学生的认知冲突,巧妙设计,将解决认知冲突的过程与学生数学学习活动巧妙结合,将模糊的、不规范的甚至是错误的数学认知,逐步规范化、数学化,可以有效激发学生的思维的浪花,会让我们的课堂教学充满思考情趣。
Let mathematics really fun, I believe this is the wish of each of our teachers. Every teacher expects that in their own classroom, students can think actively and take the initiative to construct knowledge. Designing “cognitive conflict” is an effective strategy. Respect students ’cognition, avoid or even dig deep into student’s cognitive conflicts, cleverly design, cleverly combine the process of solving cognitive conflicts with students’ mathematics learning activities, and gradually change fuzzy, irregular or even wrong mathematical cognition and gradually Standardization, mathematics, can effectively stimulate the students’ thinking spray, will make our classroom teaching is full of thinking fun.
