检测成绩曲线图就是用一个坐标系表示每名学生每次检测的成绩,横坐标表示检测次数,纵坐标表示检测成绩在毕业班或全校的排名。这个群体是稳定的,每个人每一次的检测成绩能够代表他在这个群体中的位置。从2007年到2012年,笔者通过六年时间对学校初中毕业班学生进行学习成绩曲线分析。成绩起点是进入初三第一次月考成绩,一年大约检测12～13次,将中考成绩作为最后一次检测成绩置入坐标系曲线图中。经过几年的检测成绩跟踪,
Test results curve is to use a coordinate system that each student’s test results, abscissa indicates the number of tests, the ordinate that test scores in the graduating class or school rankings. This group is stable, each person’s test scores to represent his position in this group. From 2007 to 2012, the author through six years of school junior high school graduating students to study the performance curve analysis. The starting point of the score is the first monthly test score of the third day of the test, and the test result is about 12 to 13 times a year. The test score will be put into the coordinate system curve chart as the last test result. After several years of test results tracking,
