With 850 new or significantly revised terms in addition to previously published content, the second edition of the Greenwood Dictionary of Education brings the 2003 version up to date. New content includes selected coverage of terminology from the fields of neuroscience, educational assessment, and technology, as well as updated entries on evolving educational practices and theories. Unfortunately it’s difficult to determine the scope of the additions: as a traditionally-organized alphabetical work without an index, this work—as with most dictionaries—is most useful for known- item searches. The keyword search in the ebook version does search word definitions in addition to head words, which is enormously helpful and could help a novice or general user to find related terms. In fact, this reviewer wished that a strict adherence to a dictionary format had been set aside in favor of options to optimize flexibility in searching. For a variety of users, a topical index would be quite helpful, especially given the fact that “contributing editors were also responsible for defining the boundaries of their topical areas” (x) while compiling and writing entries.
