THE PURPOSE IS TO IMPROVE THE INSTRUCTIONAL PROGRAM FOR PUPILS THROUGH CHANGES IN GROUPING PRACTICES, CURRICULUM, AND INSTRUCTIONAL TECHNIQUES, AND THROUGH MORE EFFECTIVE USE OF TEACHER STRENGTHS, INTERESTS, AND TALENTS. THE REDEPLOYMENT OF PERSONNEL AND SALARIES POSSIBLE IN THE TEAM ORGANIZATION HELPS TO CREATE NEW TEACHING JOBS WITH INCREASED PRESTIGE, STATUS, AND SALARIES, WITHOUT AFFECTING THE COSTS OF EDUCATION. DURING THE FIRST TWO YEARS, TEAMS WERE COMPOSED OF A TEAM LEADER, A COOPERATING TEACHER, AND A TEACHER AIDE, AND EACH GROUP CONTAINED APPROXIMATELY 75 CHILDREN. DURING THE THIRD YEAR, PART-TIME PROFESSIONAL INSTRUCTIONAL HELP WAS ADDED. LARGER NUMBERS OF PUPILS AND TEACHERS WERE INCLUDED IN A TEAM, AND GRADE LINES WERE CROSSED. RESEARCH ACTIVITIES CENTERED ON DEVELOPMENT OF MODELS FOR TEAM TEACHING. THE LIMITED INSTRUMENTS OF MEASUREMENT OF THE EVALUATION HAVE SHOWN, TO DATE, THAT CHILDREN ACHIEVE AS WELL ACADEMICALLY IN THE PLAN AS IN THE SELF-CONTAINED CLASSROOM. THEY ALSO SEEM TO MAKE A BETTER ADJUSTMENT TO JUNIOR HIGH SCHOOL. TEACHERS FIND CAREERS IN TEAM TEACHING MORE ATTRACTIVE. TEAM TEACHING IS AN EFFECTIVE INSTRUCTIONAL ORGANIZATION FOR FACILITATING GRADE CROSSING. INCLUDED IN THE APPENDIX ARE DETAILS OF THE EVALUATION OF ACHIEVEMENT AND ADJUSTMENT, DESCRIPTIONS OF THE ROLES OF TEAM MEMBERS AND OTHER SCHOOL PERSONNEL INVOLVED IN THE PLAN, AND A DESCRIPTION OF THE INSTRUCTIONAL PROGRAM.
