基于bs模式的教师教学质量测评管理系统.docx

摘要
摘 要
本系统所实现的教师教学质量测评管理系统是网上教学系统的一个组成部分。它主要以日益成熟的校园网为基础,学校自己的 Web 服务器与 网络相连后,使学生、教师及专家和管理员能够在任何可以上网的地方浏览和使用本系统。
本系统采用了目前已成熟的如 B/S 三层结构模式,ASP 技术,SQLServer2000 及 Web 数据库等技术。在分析传统的教师教学质量测评不足的基础上,根据现在的教学要求和计算机分析统计数据的特点,设计了测评系统,学生、同行及专家用表。特别在为消除因学生个人情感和素质高低以及班级之间对教师教学质量测评数据而产生的偏差,本文采用了两步纠偏算法来消除,力求测评数据可观真实地反映教师的教学质量。同时为确保系统的准确性和安全性,本文利用冗余信息来解决存储逻辑结构中存储数据的校验问题。
本文还利用 UML 技术从不同的视角为系统的构架建立了模型,形成了学生、系统管理员等对象的用例图、时序图、协作图和活动图。本文还对系统做了一些必要的测试工作。
开发过程中遇到的难点、问题及解决方法,快速、高效运行是所有 Web 应用程序所要解决的关键问题,本系统也是以此为目标,提出了各科目数据库独立化, 数据表单分散化,查询段代码组件化,数据传递简单化,Web 服务器功能转移化的设计思想。

ABSTRACT
ABSTRACT
This system to implement Teaching Quality Assessment Management System is ponent of the online learning system. It mainly bases on the increasingly mature work. After connecting the school-owning Web server with the , students, teachers, experts and administrators can browse and use this system at any places where it is access to the .
This system makes use of the now mature technologies such as B / S three-tier structure model, ASP technology, SQLServer2000, Web database and so on. Based on the analysis of shortages of the traditional teaching quality evaluation, the evaluation system, students’ tables, colleagues’ tables and experts’ tables are designed according to the current educational requirements and the characteristics puters’ analyzing statistical data. Particularly to remove the deviations produced by the individual student’s emotion and quality and the evaluation data from different classes, this article use two-step correction algorithm to eliminate the deviation and strive to make sure that the measurement data truly reflect the teaching quality. At the same time, in order to ensure the accuracy and security of the system, this paper employs redundant information to solve the data validation problems in the logical structure.
This article also uses UML technology to establish the framework for the system model from different angles, and forms the use case di
