摘要:学生的课程成绩通常由期末考试成绩和平时成绩两大部分组成,科学地确立平时成绩评定依据是正确认定学生学习效果和知识掌握状况的基础,也是正确评估教师教学效果和教学水平的标尺。而目前大部分教师评定学生的平时成绩主要参考学生的几次平时作业成绩,评判的依据比较单一,不能很好地反映学生的平时学习情况!本文介绍了四个评价学生平时成绩的数学模型,重点介绍了两个模糊数学模型及其分析应用,希望能给教师在评定学生平时成绩时提供一些参考。

Abstract:Students' course grades usually consist of two parts including the grades of final examinations and average studies. It lays a solid foundation for examing students' learning effects to establish average grades criterion scientifically, which retains an important measure for assessing teachers' teaching results and standards. However, at present, most teachers appraise students' average grades mainly with the reference of few previous work grades, which, can not specifically reflect students' average learning condition on account of the single criterion. The essay introduces four mathematical models of assessing the achievements of students. It is mainly about two fuzzy mathematical models and their analytic applications.

学生的课程成绩通常由期末考试成绩和平时成绩两大部分组成。期末考试是对一门课程知识和技能掌握情况的总括反映,具有全面、系统、综合的性质。但对学生而言其对课程学习的反馈作用较小,从因材施教的角度说对老师的反馈作用也没有直接的针对性。在课程教学进行过程中进行平时成绩测定,对学生学习态度、学习方法、学习内容有引导作用。因此,科学地确立成绩评定依据是正确认定学生学习效果和知识掌握状况的基础,也是正确评估教师教学效果和教学水平的标尺。本文主要研究如何科学判定学生平时成绩的数学模型,并通过具体数据来检验其合理性。
