THE BELIEF PATTERNS OF EIGHT GROUPS OF SCHOOL PERSONNEL (STUDENT TEACHERS, COOPERATING TEACHERS, PRINCIPALS, CLINICAL SUPERVISORS, METHODS PROFESSORS, EDUCATION PROFESSORS, OTHER ACADEMICIANS, AND STATE DEPARTMENT OF EDUCATION PERSONNEL), TOTALLING 976 PERSONS, AT SIX INSTITUTIONS (INCLUDING THREE STATE TEACHERS COLLEGES AND TWO LARGE STATE UNIVERSITIES) WERE MEASURED BY THE PERSONAL BELIEFS INVENTORY, THE TEACHER PRACTICES INVENTORY, AND ROKEACH'S DOGMATISM SCALE. THE FIRST TWO INSTRUMENTS MEASURE THE EXTENT TO WHICH THE SUBJECT'S BELIEFS AND PRACTICES ARE IN AGREEMENT WITH JOHN DEWEY'S PHILOSOPHY OF EXPERIMENTALISM. THE ROKEACH SCALE MEASURES RIGIDITY-FLEXIBILITY. THERE WAS GENERAL REJECTION OF EXPERIMENTAL ATTITUDES TOWARD MATTERS OF RELIGION AND MORALS AND STRONG ACCEPTANCE OF THE CONCEPTS OF FACULTY PSYCHOLOGY. CHIEFLY, COOPERATING TEACHERS WERE GENERALLY FOUND TO BE SIGNIFICANTLY LESS EXPERIMENTALLY ORIENTED AND MORE DOGMATIC THAN THE OTHER GROUPS. STUDENT TEACHERS TENDED TO FALL MIDWAY BETWEEN COOPERATING TEACHERS AND EDUCATION PROFESSORS. OF THE SEVERAL GROUPS, EDUCATION PROFESSORS WHO DO NOT SUPERVISE STUDENT TEACHERS WERE FOUND TO BE THE MOST EXPERIMENTALLY ORIENTED AND LEAST DOGMATIC. SUBSTANTIAL DIFFERENCES WERE ALSO FOUND AMONG THE SIX INSTITUTIONS AND AMONG VARIOUS GROUPS WITHIN THE INSTITUTIONS. THE AUTHOR SUGGESTED THAT THE INSTRUMENTS ARE USEFUL FOR STAFF SELECTION WITH A VIEW EITHER TO HOMOGENEITY OR HETEROGENEITY OF VIEWS. (LC)
