Experimental approaches with emotionally disturbed children in day care programs in Ohio public schools are described. A consideration of problems of identification and classification presents Quay's three dimensions of behavior, conduct disorders, inadequacy or immaturity, and personality, and lists types of behavior found in each. Seven kinds of programs for disturbed children are charted with their goals and structure; the psychoeducational approach is discussed; and behavior modification is explained utilizing research reviews and examples. The historical development of Ohio's day classes and the growth of the program from 1961 to 1967 are presented. Also presented are the level, number of units, program description, and person to contact for the 20 demonstration projects in operation, procedures for initiating research and demonatration projects, suggestions for research, and a 90-item bibliography. Appendixes provide state board of education standards for special classes, individual services, and home instruction, and application forms. (RP)
