The problem with students using Google is not that the search leader is unable to offer useful educational content. It's that finding that content using simple search terms is a difficult art to master. But some educational companies and organizations aim to make it easier to find useful educational content among the Web. They are forming a working group to come up with more detailed criteria(标准)that could eventually be added into the search lines for Google, Bing, and Yahoo !

The project was encouraged by a joint move by those major search engines to help users do more effective Web­searches. The idea behind the new education corporation is to determine a common “framework” for narrowing search results for education content—by subject area，or source type，or content type, or any number of possible criteria. The goal is also to persuade publishers of educational content to use a matching set of tags(分类)to help the search engines sort out their content more easily.

Search engines are used by college students, but they were not designed for them. This has been a subject of much  handwringing (绝望) among professors, who worry that students are not finding the most reliable content on the Internet even if more and more content providers of good fame—textbook publishers, scholars, universities and many others—have been putting useful academic resources on the open Web.

Michael Johnson, a member who will be serving on a working group devoted to developing the framework over the next six months or so, said “The project is aimed at benefiting the  publishers  of  educational  content  as  much  as students. ”
