叶澜教授在《重建课堂教学过程》一文中提到:“学生在课堂活动中的状态,包括他们的学习兴趣、注意力、合作能力、发表的意见和观点、提出的问题与争论乃至错误的回答等,都是教学过程中的生成性资源。”理想的课堂是真实的课堂。在数学课堂上,每天都有学生在出错。课堂是学生出错的地方,错误是伴随着学生一起成长的。事实上,在几年的教学过程中,我也认识到学生在学习中出现的错误未尝不是一种收获,它有积极的一面,它为我们的教学反思提供了铺 Prof. Ye Xie mentioned in the article “Rebuilding the Classroom Teaching Process”: “Students’ status in classroom activities, including their interest in learning, their ability to work, their ability to cooperate, opinions and opinions expressed, problems and disputes raised, and even errors The answers are all generated resources in the teaching process." The ideal classroom is a real classroom. In mathematics classes, students are making mistakes every day. Classrooms are where students make mistakes. Errors grow along with students. In fact, in the course of several years of teaching, I also realized that students’ mistakes in learning are not a kind of gain. It has a positive side. It provides a paving point for our reflection on teaching.
