课堂练习是学生学习过程不可缺少的重要环节,也是学生巩固知识、形成技能、发展智力的重要手段。教师透过学生的课堂练习,可以了解学生数学学习达到的水平和存在的问题,帮助教师进行总结与反思,调整和改进教学内容和教学过程。然而,在新课程实施过程中许多教师仍然常采用“剪刀+浆糊”方式编制课堂练习,不但出现学生一看就懂、一说就会、一做就错的现象,而且导致课堂教学效率降 Classroom practice is an indispensable part of students' learning process and an important means for students to consolidate knowledge, form skills and develop intelligence.
