Computer Support for Unobtrusive Assessment of Conceptual Knowledge as Evidenced in Newsgroup Postings

摘要

As the Internet brings new means of presenting information to learners, the need for meaningful assessment increases.

The tool combines a web browser with an annotation facility, a database, and special means for visualizing assessment data captured with the tool.
