《义务教育数学课程标准》指出:评价的目的是全面考查学生的学习状况,激励学生的学习热情,促进学生的全面发展。评价是教师反思和改进教学的有力手段。教师对学生数学学习的评价,不仅要关注学生知识与技能的理解和掌握,更要关注他们情感与态度的形成和发展。 “Compulsory Education Mathematics Curriculum Standard” points out: The purpose of evaluation is to comprehensively examine the students ’learning situation, encourage their enthusiasm for learning and promote the students’ all-round development. Evaluation is a powerful tool for teachers to reflect on and improve their teaching. Teachers’ assessment of students’ mathematics learning should not only pay attention to the understanding and mastery of students’ knowledge and skills, but also pay attention to the formation and development of their emotions and attitudes.
