This paper presents several samples from a Thesaurus of educational technology (ET) terms that is based on the analysis of recent publications (journal articles, conference papers, and books), various related texts, and Internet databases. The Thesaurus pulls together all the knowledge acquired in the development of ET from 1990 through 1999, to update the existing inventory of terms in this field and to make up as complete a list as possible of the current terms describing all the areas of ET, to single out separate areas of ET and to structure it as a special field, to differentiate between separate phenomena and specify the meaning of existing terms. The Thesaurus describes each term in its various collocations (word combinations) with other words. Terms are arranged in"articles" in alphabetical and topical (subject area) orders. (AEF)
