This book lists 4,876 descriptors selected from the Thesaurus of ERIC Descriptors, 9th Edition, with their Japanese language equivalents. It was prepared by personnel of the Center for Educational Technology at Aichi University of Education, which, since 1978, in cooperation with Unesco's Asian Programme of Educational Innovation for Development (APEID), has been collecting and preserving research reports published in Japan related to educational technology, as well as preparing and publishing English language abstracts of these reports. In order to make information about these reports more accessible to researchers and organizations, the project has also included the assignment of keywords. This book was prepared to assist researchers from other countries to use this system of keywords, and is a step toward preparation of Japan's own educational thesaurus. It does not include descriptors which had the comment "invalid descriptor" under the scope notes nor does it include identifiers. The second section of the book is a listing of the Japanese terms (in "kana" order) followed by their English equivalents, making it possible to back reference from Japanese to English. (DMC)
