小学数学课堂是一个繁忙的场所,数学学科的层次性、逻辑性决定了课堂的复杂多变,纵使教师的经验多么丰富,也会经常出现“当局者迷、旁观者清”的尴尬局面。回顾每个人的课堂教学,虽然我们久经沙场,但是我们的课堂很少被人系统、全面地观察过,因此,也就很少收到有关如何提高教学效能的有价值的反馈信息或建议。众所周知,成功的教师应该善于观察和体会,学会用观察、描述、思考,对自己的课堂教学有一个全面的分析,以便能对课堂教学做出持续的改进,最终达到“以生为本,以学定教,聚焦课堂,提 Primary mathematics classroom is a busy place, the level of mathematics disciplines, logic determines the complexity of the classroom, even if the teacher's experience is rich, there will often be ”authorities fans, bystanders clear “ embarrassing situation.
