The effects of annotated web documents, using context highlighting, on quiz performance and preparation time

Highlighting is an annotation method frequently used to indicate importance. This document introduces context highlighting of web documents and demonstrates that passive readers may benefit from summaries produced by context/keyword highlighting. HighBrow, a prototype browser developed to enable active readers to create context/keyword summaries from web documents, is introduced. This document provides the results of an experiment using three groups of passive readers: the first group reading an entire document; the second group reading a context/keyword summary provided by HighBrow; and the third group reading a keyword only summary (provided by a modified version of HighBrow). The experiment was developed to measure quiz performance, preparation time, and efficiency (quiz score divided by time).
