Multi-Age Teaming (MAT) programs were implemented at Crabapple and McNair Middle Schools in Fulton County, Georgia, in the fall of 1993, and at Camp Creek Middle School in the fall of 1994. An important goal of these programs was the creation of school families within schools with multi-age teams of sixth-, seventh-, and eighth-grade students. At Crabapple, the primary goal was to enhance self-esteem; whereas at Camp Creek and McNair, the primary goal was to raise academic achievement. Program evaluation began at Crabapple in 1993, and evaluation began at Camp Creek and McNair in 1995. The evaluation designs at all sites involved quantitative methods, including analysis of Iowa Test of Basic Skills (ITBS) scores, Coopersmith Self-Esteem Inventories (CSEI) results and attendance and behavior referral data; and qualitative methods, including surveys and interviews conducted with parents, students, and teachers. This progress report discusses the results of the evaluation. For Crabapple and Camp Creek, quantitative results are given for achievement assessed by the ITBS, for self-esteem as assessed by the Coopersmith results, and for student affect through absenteeism and disciplinary referral records. Data for McNair had been collected but not yet analyzed. Qualitative results from interviews covered multi-age grouping, self-esteem, peer mediation, interdisciplinary teaching, scheduling, and hands-on learning. For Crabapple, three years of survey results are given. Survey results for Camp Creek and McNair were not yet available. (Contains 3 figures and 6 tables.) (LPP)
