试卷讲评是在学生练习或考试之后,教师从学生做题情况中获取反馈信息,并对学生存在的知识缺陷进行矫正教学,从而提高学生思维和解题能力的一种课型。该课型要求教师对学生答题数据进行整理发掘,找出学生在答题过程中的问题,通过讲评,弥补在教学上的不足,需要较强的时效性和针对性,才能提高讲评的有效性。然而,由于传统的手工阅卷方式存在着数据分析的效率低下,数据不完整,缺乏横向比较等诸多问题,难以满足基层教师对高效试卷讲评的数据需求。
Paper review is the student practice or examination, the teacher from the students do the situation to obtain feedback information, and the existence of the students to correct the deficiencies in teaching, thereby enhancing the ability of students thinking and problem solving a course. The course requires teachers to sort out the students’ answers data to find out the students in the process of answering questions, through comments, to make up for the lack of teaching, the need for strong timeliness and relevance in order to improve the effectiveness of the comments. However, due to the inefficiency of data analysis, incomplete data and lack of horizontal comparison, the manual manual marking method can not meet the data needs of grass-roots teachers to comment on efficient papers.
