课堂练习是数学课堂教学的重要组成部分,其有效性在很大程度上影响着教学的成败。进入新课程以来,我对课堂练习在课堂上的有效性进行了关注,结合上课经验和外出听课的启示,总结了课堂练习的精髓在于求新(提供新鲜的东西引起兴趣)、求活(挖掘习题本身的内在力量保持兴趣)、求近(揭示知识的应用价值提高兴趣)。 Classroom practice is an important part of mathematics classroom teaching, its effectiveness to a large extent affect the success of teaching. Since entering the new curriculum, I have paid close attention to the effectiveness of classroom exercises in the classroom. Based on my experience in class and the lessons learned from going out to class, I conclude that the essence of class exercises is to seek new things (to provide fresh things to arouse interest) Exercises themselves to maintain interest in the internal forces), seeking closer (revealing the value of knowledge to increase interest).
