ERIC abstracts on open space schools, announced in RIE through August 1972, are presented. The key terms used in compiling this collection are "open education," and "open plan schools." The documents present materials defining open space schools and open education, comparing open space schools with traditional schools and open education with traditional education, and detailing plans for the implementation and operation of open plan schools. The following information is presented for each document: personal or institutional source, title, place of publication, commercial publisher, publication data, number of pages, ERIC document ("ED") number, price of the document if it is available from the ERIC Document Reproduction Service, and the abstract. The documents are numbered and listed alphabetically by the authors' last names. A subject index refers to the document listing number. The subject terms, arranged in alphabetical order, are identical to those contained in the subject index of RIE. (Author)
