课堂练习是使学生掌握知识,形成技能,培养学生运用知识解决实际问题的有效手段,是学生学习数学的重要环节。它对优化课堂教学过程,提高课堂教学效率,拓展学生思维空间,起着重要的作用。教学中教师应根据不同的教学内容精心设计课堂练习,促进学生思维的发展。在《分数大小的比较》教学时,我请同学们课下查阅各种关于本课的资料,同时我也查阅了许多课外资料,设计了多种形式的练习题。课堂上组织学生交流、讨论、求异,充分调动学生的积极性,鼓励学生积极思维,让学生在争论中寻求解决问题的方法。这样不仅激活了学生的思维,而且使我受到很大的启迪。为此,我和同学们归纳了以下几种分数大小比较的方法。 Classroom practice is an effective way for students to master knowledge, form skills and train students to use knowledge to solve practical problems. It is an important part of students’ learning mathematics. It plays an important role in optimizing classroom teaching process, improving classroom teaching efficiency and developing students’ thinking space. Teaching teachers should be based on different teaching content carefully designed classroom exercises to promote the development of student thinking. In the “comparison of scores” teaching, I asked the students to access a variety of information about this lesson, and I also read a lot of extra-curricular information, designed a variety of exercises. Classroom students to exchange, discuss, seek differences, and fully mobilize the enthusiasm of students and encourage students to actively think, so that students in the debate to find ways to solve the problem. This not only activated the thinking of students, but also greatly enlightened me. For this reason, my classmates and I summarized the following methods of comparing the scores.
