课堂是演绎师生智慧的舞台,课程评价是新一轮课程改革的重要内容之一。《数学课程标准》指出:“评价的目的是全面了解学生的学习状况,激励学生的学习热情,促进学生的全面发展。”由此可见,评价具有检测、导向和激励等功能。但是由于长期受“应试教育”的影响,在数学课堂教学中对学生的评价,往往形式单一,内容狭窄,常采用“对”与“错”、“好”与“坏”的二分法评 Classroom is the stage to interpret the wisdom of teachers and students. Curriculum evaluation is one of the important contents of the new round of curriculum reform.

However, due to the long-term influence of “examination-oriented education ”, the evaluation of students in math classroom teaching tends to be single in form and narrow in content, often using “wrong”, “wrong”, “good” “Bad ” dichotomy evaluation
