Web Science Curriculum Filter/Editor

万维网正日益成为用户计算环境的综合扩展，通过Web浏览器对内容进行索引和检索。Web浏览器越来越多地被用作科学课程的传递机制，既可以作为本地内容在CD rom上传递，也可以作为基于服务器的材料传递。传统的科学课程通常是静态的，因为它们是在印刷媒体上讲授的。事先印在书本或讲义上的内容是不能更改的。任何变化都必须以额外讲义或在黑板上解释的方式对外公布。网络为我们提供了改变这种状况的技术支持。在这项工作中，我们建议实现一个架构，允许教师修改课程，因为它是通过网络浏览器呈现的。这将允许教师定制基于网络的课程，以满足特定需求。例如：材料列表可以用不同的列表代替。根据学生的背景个性化的例子可以是，必要的地方可以添加额外的注释和解释，可以添加交叉参考和补充书目信息。原来的页面将保持不变，只有用户对它的看法会改变。该方法的一个工作原型已经通过PFSMETE部分资金的支持得到实施。要把它变成一种足以传播的工具，还需要做更多的工作。

DGE-0003883The World Wide Web is increasingly becoming an integrated extension of users' computing environments, with content indexed and retrieved through Web browsers. Web browsers are increasingly being used as a science curriculum delivery mechanism, for both books delivered as local content on CD ROMs as well as server-based material. Traditional science curriculum has often had a static presentation due to having been delivered on printed media. What was printed ahead of time in books or handouts could not be changed. Any changes would have to be attached externally by way of extra handouts or explanations on the board. The Web gives us the technological affordances to change that. In this work we propose implementing an architecture that allows an instructor to modify curriculum as it is presented through a web browser. This would allow a teacher to customize web-based curriculum to fit a particular need. For example:A list of materials could be substituted with a different listAdditional examples personalized to the students' context could be thatExtra notes and explanations could be added where necessaryCross-reference and supplementary bibliographic information could be added.The original page would remain unchanged, with just the users' view of it that would change. A working prototype of this approach has already been implemented through the support in part of PFSMETE funding. Additional work is needed to turn it into a tool that is enough to be disseminated.
