研究背景

近几年来，随着地方高等院校办学规模的不断扩大，为了适用社会发展需要，地方高校将应用

型人才培养作为学校的人才培养目标。为了适应学校应用型人才培养目标，各专业尤其是理工科专

业人才培养方案中加强了实践教学环节，因此，实践教学管理成为高等院校教学管理的重要内容之

一。

目前高校教学管理都采用了基于网络的信息化管理系统，但是由于实践教学在课程教学时间安

排、课程教学内容、周数等方面不同于传统的课程教学，通用的教学管理系统不能很好地适应实践

教学管理。根据我系实践教学的需求，基于 java web 设计与实现了一个实践教学管理系统，满足实

践教学管理的需求要求，更好地实现实践课程教学管理。

研究目标

调研我系的实际情况，根据软件工程的思想，设计并开发了一个适合我系实践教学管理的系统，

该系统包括学生和教师信息的管理、实践教学管理、学生成绩管理等功能，基本上满足了实践教学

的需求。

随着科技发展，现代的计算机信息技术不断进步，在学校系统管理方面逐步开始普遍借助计算机处理数据来完成对数据的操作，对于实验教学实验教学系统所设计的管理及数据保存而言极为常见，例如主页、个人中心、学生管理、教师管理、班级管理、实验教学信息管理、系统管理等，这给管理者的工作带来了巨大的挑战，用传统方式处理归类大量的信息，都是通过笔记的方式进行详细信息的统计，计算机普及之后，逐渐开始使用电脑软件将信息输入到电脑内进行统计，但想要统计数据信息仍然比较繁琐和困难，而通过计算机对数据进行处理排版相对人工而言更为简单省力，因此实验教学实验教学系统顺应需求产生；该系统可以为用户提供了上传信息的便利，同时方便了管理员查看、维护系统，还可以通过客户需求对系统进行相应的调整和维护等；同时对于用户而言，可以随时查看网站内的各种信息，管理员可以非常轻松地获取到相应的数据信息并进行分类处理等，节省了用户和管理员在各个方面需要的时间。

本论文实验教学实验教学系统主要牵扯到的程序基础理论等。如果加以改造使用，普及范围会更为广泛，可以提高工作人员的工作效率。
