在对学生考核时,学生的平时成绩应该与期末成绩呈现相同的趋势,即一个学生平时成绩高,其掌握实际知识的能力就会高,理论上其期末成绩也应该高,反之亦然。本文以楼宇自动化设备安装与维护专业的15位教师所授的15门不同课程成绩进行统计,分析平时成绩和期末成绩的正态分布情况及二者之间的相关性。由结果可知,平时成绩和期末成绩相关性并不显著,需要加以改进,文中提出了相应的对策。
When examining students, the students’ usual grades should show the same tendency as the final grades. That is, a student usually has high grades and has a high ability to master practical knowledge. Theoretically, his final grade should also be high, and vice versa. In this paper, fifteen different course scores awarded by fifteen teachers specializing in the installation and maintenance of building automation equipment are counted to analyze the normal distribution and the normal distribution of the final grades and their correlations. From the result, we can see that the correlation between usual grade and final grade is not significant and needs to be improved. Corresponding countermeasures are put forward.
