数学教学离不开评价,评价常需要通过书面测验形成量化指标来全面了解学生数学学习的过程和结果,从而激励学生的学习、改进教师的教学。因此,科学合理地设计一份高质量的试卷是至关重要的。但是,在现实生活中无论是何种类型的考试命题,受时间和精力所限,不可能所有的试题都是命题者创造性地编制出来的,其中的大部分试题还是由教材中的习题、往年的考试题和各种参考资料中的习题等改编而来。特别是数学教材中的习题,具有很强的基础性、典型性与示范性,它是教师教学 Mathematics teaching can not be separated from evaluation. Evaluation usually needs to form a quantitative index through written test to fully understand the process and result of students’ mathematical learning so as to stimulate students’ study and improve teachers’ teaching. Therefore, the scientific and rational design of a high quality papers is crucial. However, in real life no matter what type of test proposition, subject to time and energy constraints, it is impossible that all the questions are creatively prepared by the proponents, most of which questions or by the textbook exercises in previous years The exam questions and a variety of reference exercises in the adaptation. In particular, math textbooks exercises, with strong foundation, typical and demonstration, it is the teaching of teachers
