2008 Update for the Educational Development Center

EDC Progress Report June 2007

The research carried out by Education Development Center, Inc. (EDC) focused on helping middle-grades students improve reading comprehension in social studies by building word knowledge through the use of a web-based tool, Visual Thesaurus (VT). VT allows the reader to look up a word directly from a piece of electronic text. It does not directly define words; rather it presents an array of concepts that capture the varied word meanings. The features of VT align with the following e-text resources: translational, illustrative, enrichment, and collaborative. From August, 2006 to May 2007, EDC carried out a series of four brief design studies, with each one building on findings of the previous study.
