The major portion of this report for fiscal year April 1967 through March 1968 consists of summaries of research and programs of the past year (Part 1) and projections of those for the coming and subsequent years (Part 2). Part 1 describes (1) purposes, methods, and results of projects in the three major "domains" of "variables" studied and (2) facilities and research services that were active during the year. Included are reports on 14 subcategories in the behavioral domain where the emphasis is on various technical skills of teaching, on three subjects in the personological domain (teacher traits and characteristics), and on five elements of the institutional domain (teacher roles in their institutional setting). Part 2 is organized around three subdivisions of the major educational problem which has become the focus of the Center's program: the fundamental reformulation of the role of the teacher in the decades ahead. The three subproblem areas are heuristic teaching (teaching aimed at self-motivated and sustained inquiry which emphasizes affective as well as cognitive processes and places high premium upon the uniqueness of each pupil, teacher, and learning situation), the environment for teaching (especially school organization and management), and teaching the disadvantaged. Included also in the report are a short section on administrative and support programs, one on Center management and administration, and a bibliography of Center publications.
