This glossary prepared by the International Council of Educational Media (ICEM) groups in one volume English and French terms related to educational technology in order to facilitate understanding of these terms, and to promote and encourage communication at the international level. Analysis of terms from the fields of audiovisual teaching, programmed learning, and educational television and documentation, produced an inventory of nearly 3,000 terms which were edited by teams of experts in three languages to determine which were the most important terms according to criteria of relevance and frequency of use. This list contained about 100 words pertaining to computer technology. Following revisions by various groups, the final glossary contains almost 2,000 entries. It has been published in three versions: English-French, French-English; English-Spanish, Spanish-English; and English-Russian, Russian-English. Entries were classified in alphabetical order with the determiner before the noun in languages where appropriate. The definitions proposed by the International Electrotechnical Commission and the International Organization for Standardization were retained whenever possible. A 33-item bibliography is provided and lists of the members of working groups constituted by the ICEM are appended. (ALF)
