在初中数学教学中,既需要学生通过自主探究与合作交流获得知识,还需要通过有效的练习巩固知识,提升学生的数学素养,帮助学生积累起丰富的数学活动经验.针对学习内容设计有效的数学练习题,让学生在做题中得到训练,为后续学习积累解题经验.因此,在设计练习时,要做到因人而宜、因具体内容而定.一、不同内容,不同练习,让训练有目的学习内容的不同,对于学生要求掌握的侧重点也就不同.因此,在教学中,教师要针对所学知识的 In junior high school mathematics teaching, it not only needs students to acquire knowledge through independent exploration and cooperation and exchange, but also needs effective practice to consolidate knowledge, enhance students’ mathematical accomplishment, and help students to accumulate rich experience in math activities.Design effective mathematics for learning content Exercises, so that students can get training in doing the questions for the follow-up study to solve the problem-solving experience, therefore, in the design practice, to be suitable for the individual, depending on the specific content of one, different content, different exercises, Training purposeful learning content is different, for the students to master the emphasis is also different, therefore, in teaching, teachers should learn knowledge
