This is the first of a series of Capsule Bibliographies on current issues in urban and minority education. It is a selection from a computer search using suitable descriptors matched against a standard Educational Resources Information Center (ERIC) Clearinghouse profile for urban and minority concepts. Such descriptors (subject headings) as grouping procedures, cluster grouping, grouping (instructional purposes), heterogeneous grouping, homogeneous grouping, student grouping, age grade placement, flexible scheduling, and ability grouping are used to encompass the concept of grouping practices. The bibliography covers materials in the ERIC System from January 1970 through March 1976. The cited items are arranged exactly as they have been printed by the computer. Citations are in descending order of ERIC number. Documents follow the journal articles in the bibliography. A categorized index to the references is provided. (Author/AM)
