基于全文文档检索技术的化学教学模式

为了利用网络资源进行化学教学，提出了使用全文文档检索技术整合网络资源进行教学的模式。该技术由3部分组成：一是文档系统，各种格式的文档以文件的形式在服务器硬盘上使用文件系统进行组织。二是全文检索系统，使用Index Server对文档进行过滤和索引。三是检索系统，以IIS（Internet Information Server）为Web服务器，利用ADO访问Index Server数据库，使用ASP编程，实现检索和排序。实践证明该模式实现容易，操作简单，性能优秀，适合于大学化学教学。

New chemistry teaching model based on full-text searching

For the using of websources in chemistry teaching, the full-text searching and retrieving management system are integrated to make a new teaching model combined with websources. The technology can be divided to 3 parts: first is the document system that organize different types of documents in the server; the second is full-text searching system that use Index Server to filter and index the documents; the third is retrieving system that use IIS (Internet Information Server) as web server, show the retrieving results by ADO visiting the Index Server database. The teaching practice showed this simple and applied model is applicable on chemistry teaching in college.
