THIS REPORT DISCUSSES ENVIRONMENTAL CONSIDERATIONS IN THE DESIGN OF DENTAL SCHOOL FACILITIES AS RELATED TO THE EDUCATIONAL NEEDS OF STUDENTS AND FACULTY. TWO TYPES OF NEEDS ARE IDENTIFIED--(1) PHYSICAL, INCLUDING A FUNCTIONAL ANALYSIS OF THE PHYSICAL NEEDS IMPOSED BY THE TASKS TO BE DONE, AND (2) PSYCHOLOGICAL, INCLUDING MOTIVATIONAL, SOCIAL, AND PERCEPTUAL ASPECTS. THREE PILOT STUDIES WERE CONDUCTED, CONSISTING OF INTENSIVE INTERVIEWS AND QUESTIONNAIRES GIVEN TO STUDENTS AND FACULTY ON A NUMBER OF DENTAL SCHOOLS. THE STUDIES IDENTIFIED FACTORS IN THE ARCHITECTURAL ENVIRONMENT RELATED TO THE SATISFACTION OF VARIOUS PHYSICAL AND PSYCHOLOGICAL NEEDS. THE RESULTS INCLUDED (1) LOCATIONS FOR INFORMAL LEARNING, (2) PERCEIVED SATISFACTION OF NEWER BUILDINGS AS HIGHER IN BOTH TYPES OF NEED, AND (3) FACULTY SATISFACTIONS AND INTERACTIONS AS RELATED TO SCHOOL LAYOUT. THE CONCLUSIONS DISCUSS THE SOCIAL FUNCTIONS OF ARCHITECTURE IN TERMS OF INFORMAL INTERACTIONS IN THE FRAMEWORK OF ROUTES, NODES, ZONES, AND MIXES. A BIBLIOGRAPHY IS INCLUDED. (MM)
