Brooklyn Center of Long Island University has developed a number of student teaching centers. (Such "centers" are schools with which an agreement has been reached providing for the placement of student teachers in concentrated numbers, thus allowing for resident supervision. An extension of the Campus School concept, they continue the trend toward formal agreement between colleges and public schools in concern for teacher preparation.) Resident college supervisors (full-time faculty members with usually one-half to three-fourth of their teaching load consisting of the supervision of student teachers in one school) spend 12 to 18 hours a week in the school, making them available also for conference and other resource services. The role of the college coordinator of field work (a full-time administrator with faculty rank) involves assigning supervisors and student teachers to positions at specific centers. The coordinator keeps in close contact with each of the schools, meets frequently with students, and continually discusses the field work program with divisional faculty. When students are accepted into the program, they are invited in groups of 10 to 12 to two-hour conferences with the coordinator; the group dynamics approach to student teaching in urban schools gives the coordinator a perceptive view of each student in anticipating that student's readiness for a given assignment.
