【摘要】 开发信息技术技能考核系统的主要目的就是在“学分制”、“工学交替”的背景下,帮助中职学校教务部门提高工作效率,实现信息技术类课练习、比赛、技能考核信息管理以及流程的系统化、规范化和自动化。本文主要针对中职学校技能考核存在的问题及传统考试系统的不足,提出以技能为中心建立中职学校信息技术技能考核系统的设计方案,基于MVC模式并利用ASP技术、SQL数据库对系统进行编程开发,实现了系统的考核课程管理、题库管理、试卷生成、用户管理、考核信息发布、技能考核、试卷提交、考核成绩查询等功能。采用DOM技术使数据库中存储的数据量相对减少,减轻了数据库的压力,提高访问速度。采用自适应遗传算法解决了考核中的组卷问题。通过客户端脚本计时,定时向服务器端发送信息解决了技能考核过程意外中断的计时问题。该系统具有一定的可扩展性和通用性,只要对系统稍加修改即可适应中职学校不同专业的技能考核需要,具有一定的推广价值。更多还原

【Abstract】 The main purpose of developing the Information Technology Skill Inspection System in Secondary Vocational School (SVS) is to help the teaching department improve the efficiency and accomplish the systematization, the normalization and the automation of the management of the information and the process of the practice, the competition, the skill inspection of the courses such as the Information Technology on the background of "scroe bank" and "the substitution of work and study" .Focusing on skills, the thesis puts forward the design solution of setting up the IT skill , which employs the technology of ASP and SQL database to develop the system by programming and accomplish the functions for the curriculum exam management, the management of the database and the user, the announcement of the information, the skill inspection, the establishment of the paper, the search of the score,etc.The amount of data stored in the database is relatively decreased by employing the technique of DOM, which relieves the pressure of database and speeds up runing. The problem of paper organization is solved by using the adaptive genetic algorithm. The problem of unexpected interrupted timing while inspecting skills is solved using the client script time and regularly send messages to the server-side.The system is of a certain value of the expansion and the generalization, it can be adapted to the need of skill inspection for different specialization in SVS, as long as the system is modified slightly, therefore, it is of a certain value of extending.更多还原
