DEVELOPMENT OF OPEN-DATABASE FOR WEB-BASES TEACHING MATERIALS IN SUBJECT "IT"

“it”课程于2003年引入高中，其目的是在中学教育中进行信息技术教学。这门学科本身就需要信息技术的应用，需要大量的教材作为教育资源。本研究计划的目标是建立教材资料库，并在网上分发教材，以支援课程的教学。在数据库的建设中，既要允许教师自行登记网上教材的信息，又要允许数据库的用户就教材的创作和使用交换意见。开发的目标是：(1)包括教师在内的任何人都可以使用数据库（开放性）(2)教师可以自行注册教材信息（自愿性）(3)教案可以重复使用，为教材的使用提供建议（可重用性）(4)教师可以交换对教材的意见（可交换性）该项目历时两年开发了目标系统，并于2006年4月开始服务。开发的网络教材数据库提供了多种检索工具，并促进了教案的重复使用，以支持网络教材的使用。系统还实现了信息管理代理，以保证数据库中存储信息的可靠性和安全性，这是开发系统的原始特点。

SUBJECT "IT", WHICH WAS INTRDUCED INTO HIGH-SCHOLL IN 2003, AIMS AT TEACHING INFORMATION TECHNOLOGY IN MIDLE AGE EDUCATIONS. THE SUBJECT REQUIRES APPLICATION OF INFORMATION TECHNOLOGY ITSELF AND NEEDS MANY TEACHING MATERIALS AS EDUCATIONAL RESOURCES.THE OBJECTIVE OF THE RESEARCH PROJECT IS TO BUILT BATABASE OF TEACHING MATERIALS THAT ARE DISTIBUTED ON THE WEB FOR THE LESSONS OF SUBJECT IT IN ORDER TO SUPPORT THESE LESSONS. IN BUILDING THE DATABASE WE NEED TO ALLOW THE TEACHERS OF IT TO REGISTER INFOEMATION OF WEB-BASED TEACHING MATERIALS BY THEMSELVES AS WELL AS ALLOWING THE USERS OF THE DATABASE TO EXCHAGE THEIR OPINIONS ABOUT CREATION ADND USAGE OF THE MATERIALS.THE GOAL OF THE DEVELOPMENT ARE THE FOLLOWINGS :(1)ANYONE CAN USE THE DATABASE INCLUDING TEACHERS OF IT (OPENNESS)(2)TEACHERS CAN REGISTER INFORMATION ABOUT TEACHING MATERIALS BY THEMSELVES (VOLUNTARY)(3)LESSON PLANS CAN BE REUSED FOR SUGESTING USAGE OF TEACHING MATERIALS (REUSABILITY)(4)TEACHERS CAN EXCHANGE THEIR OPINIONS ABOUT TEACHING MATERIALS (EXCHANGEBILITY)THE PROJECT DEVELOPED THE TARGET SYSTEM IN TWO YEARS AND START SARVICE FROM APRIL 2006.THE DEVELOPED DATABASE OF WEB-BASED TEACHING MATERILAS PROVIDES MANY KIND OF SEARCH FACILITIES AND PROMOTE REUSING LESSON PLANS TO SUPPORT USING WEB-BASED TEARCHING MATERILAS. ALSO THE SYSTEM IMPLEMENTED INFORMATION MANAGEMENT AGENT SO AS TO MAKE SURE THE RELIABILITY AND SAFETY OF STORED INFORMATION IN THE DATABESE, THAT IS THE ORIGINAL FEATURE OF THE DEVELOPED SYSTEM.
