学生作业,是课堂教学的延伸。随着教育改革的不断深入,人们越来越重视作业在对学生认知能力评价中所起的作用。作业的主要作用有:启迪学生解题思路、培养学生解题能力、理解教学中的重难点以及反馈学习和教学状况。但是不容乐观的是,既有的作业反馈模式却无法体现这个重要的作用。笔者通过本研究尝试调查数学作业、访谈任课教师和个案学生,找到学生的错误成因,最后提出教学策略建议,并以具体课例进行实践。一、初中数学作业的错误原因诊断
Student homework is an extension of classroom teaching. With the deepening of education reform, people pay more and more attention to the role of homework in the evaluation of students’ cognitive ability. The main functions of the homework are as follows: inspiring students to solve problems, cultivating students’ ability to solve problems, understanding heavy difficulties in teaching, and feedback learning and teaching conditions. However, it is not optimistic that the existing homework feedback model can not reflect this important role. Through this study, the author attempts to investigate math homework, interview teachers and case students, find out the causes of students’ mistakes, and finally put forward teaching strategies and suggestions, and carry out the practice with specific examples. First, junior high school math homework error reason diagnosis
