While the previous two parts of PAIR report focused entirely on the impact of PAIR on teacher professional development and on student standardized academic test results, Part 3 of the report is organized into seven sections that present the analysis of multiple student arts integration learning assessment results and the intersection among teacher-student outcome variables by the final year of the project. The results are reported in seven different sections, each featuring its own table of contents, list of figures and tables, and an appendix: A. Snapshots of Arts Integration (SAIL) Interview Response Ratings analyzed for control treatment and within-treatment school differences in students' understanding of arts integration processes and connections; B. PAIR Student Survey Responses analyzed for control-treatment school differences in the perception of arts integration practices in their classrooms and control-treatment schooldifferences in the presence of classroom culture practices most highly associated with PAIR professional development goals and outcomes; C. PAIR Partnership Arts Integration Learning (PAIL) Student Work Samples analyzed for qualitative differences among within PAIR treatment school classroom practices and in relation to the documentation and assessment goals for the PAIR project; D. PAIR Portfolio Conference Performance Assessments of teacher verbal reflections and student individual and group performance assessments analyzed for qualitative differences in PAIR treatment school PAIR student work and portfolio conference performance assessments. E. PAIR Portfolio Conference Performance Assessments of student individual and group performance assessment data analyzed statistically for their relationship to SAIL assessments, PAIL classroom ratings, and teacher portfolio conference performance data. F. PAIR Treatment School Teacher-Student Outcome Intersections analyzed for statistically significant degrees of association between teacher professional development variables analyzed and student learning outcome data.
