摘要:本文主要是讨论如何解决根据学生成绩评估教学质量的信息化问题。针对该问题,利用VB语言做了一个学生成绩评估系统,该系统能简化根据学生的成绩来对教学质量进行评估的过程,使老师的教学成果、学生的成绩变化都一目了然。为达到所定的目的。本系统主要使用了VB语言,数据库等工具。学生的成绩数据主要储存于SQL数据库,因此需要首先对数据库进行操作、处理。本文首先概述了信息化教育的发展情况,讲明了开发学生成绩评估系统的必要性,接着阐述了学生成绩评估系统的基本设计思想及实现方法。并以该系统为应用实例,介绍了用VB语言进行绘制图表以及使用及操作数据库的一些要注意的地方。

ABSTRACT:
This text mainly discusses how to solve according to the information-based problem of assessing teaching quality of student's achievement. To this question , utilize VB language to do a student's achievement to assess the system, this system can simplify the course evaluating teaching quality according to students' achievement , all very clear when making the teacher's teaching achievement , students' achievement change. In order to achieve the goal of fixing. This system has used VB language, tools , such as database ,etc. mainly. Students' achievement data are stored in SQL database mainly, so need to operate , deal with the database at first. This text has sum up the development that the informationization educates at first, has explained student's achievement of developing and assessed the systematic necessity, then has explained the basic design philosophy of assessing system of student's achievement and implementation method . And regard this system as instance of using, is it go on chart of drawing and use and operate some places that should pay attention to of the database with VB language to introduce.
