| 摘 要： | 利用SPSS对选修课技术经济学成绩进行统计分析,对期末成绩按本一与本三、性别以及文理专业间的不同进行了两独立样本T检验,并按学院进行了聚类分析和单因素方差分析。结果表明,选修该课程的学生的文理学术背景对其学习成绩没有太大影响;本一学生的考试成绩明显高于本三学生的成绩;性别差异并不会对成绩产生显著影响;不同学院之间在成绩上存在显著差异。因此在教学上,建议对本一、本三的学生分开讲授,根据学院之间的聚类分析结果安排得分相近的学院可统一授课,做到因材施教,以取得更好的教学效果。

| Abstract: | This paper analyzes the evaluation method of technology economics by SPSS software.T-test was used to get the contrastive results of students’ final score between first-and-third batch students,liberal arts and science major,male and female students,which made cluster analysis and one-way anova.The results show that scores were not significantly affected by major and gender,the first-batch students got significantly higher score than that of the third-batch students,and gap between colleges was wide,too.In this case,the paper suggests different teaching way for the first and third batch students.According to the clustering analysis,give unified lectures to institutes of similar scores.Better teaching effect could be got if we made individual teaching. |
