认知冲突是一个人已经建立的认知结构与当前面临的学习情境之间暂时的矛盾与冲突,是已有的知识和经验与新知识之间存在某种差距而导致的心理失衡.根据现代心理学研究表明,在课堂教学中设置认知冲突,可以为学生提供真实的学习背景,模拟解决实际问题的过程.因为在真实的学习背景或解决实际问题的过程中一定存在矛盾与冲突,不可能“伸手就摘到果子”.如果教师过多地为学生铺设台阶,使学习道路过于平缓,学生对所学知识就不会 Cognitive conflict is a temporary contradiction and conflict between the cognitive structure one has established and the current learning situation. It is the psychological imbalance caused by the existing gap between knowledge and experience and new knowledge. Psychological research shows that setting cognitive conflicts in classroom teaching can provide students with a real learning background and simulate the process of solving practical problems. Because there must be contradictions and conflicts in the real learning background or the process of solving practical problems. Maybe “Take a hand to get the fruit.” If teachers put too many steps on the students and the learning path is too flat, students will not learn what they have learned.
