教师在平时的作业批改中,往往会发现学生有错题相对集中的现象,究其原因,这类题目的设计和表述具有一定的灵活性和干扰性,需要学生仔细思考,否则容易出错。我们把这些学生容易产生解题错误的共性题目,称之为数学教学中的易错题。易错题的解决能较好地暴露学生学习的困惑,反馈教学的效果,是教学研究的重要素材。因此,建立数学错题集,用不同的方式分析易错原因,对改善教师的教 Teachers in the usual homework modification, students often find the phenomenon of relatively concentrated error phenomenon, the reason, the design and presentation of such topics have some flexibility and interference, students need to think carefully, or prone to error. We put these students prone to error-solving common problem, called the mistakes in mathematics teaching questions. Easy to solve the problem of error can better expose the students learning puzzles, the effect of feedback teaching is an important material for teaching and research. Therefore, the establishment of mathematics wrong title set, with different ways to analyze the reasons for error-prone, to improve the teaching of teachers
