This volume contains the proceedings of six Head Start research seminars held in Washington, D.C., from June 11, 1968 to April 18, 1969. The subject areas for each seminar were drawn from what was considered to be the most pressing issues in early childhood education research. There were (1) motivation, (2) the teacher and classroom management, (3) Head Start populations, (4) health and nutrition in early childhood, (5) intervention in family life, and (6) the teacher in intervention programs. The people who participated in and prepared papers for these seminars were selected by members of the Head Start Advisory Council and other eminent professionals, and were considered to be "expert authorities" in the individual subject areas. The emphasis of the seminars was, as evidenced by the subject areas settled on, improvement of educational opportunity for the disadvantaged child. The seminar on motivation, for example, stressed such poverty problems as learned helplessness, cooperation, and delay of gratification. The papers in this volume represent the final drafts after they had been exposed to careful criticisms and suggestions by those who heard them. A brief summary of the thrust of the seminars is included in the introduction. Seminar 1 on motivation is available as ED 024 464. The remaining seminars will appear in future issues of Research in Education. (MH)
