This document provides information about an evaluation of a collaborative learning program at a middle school with approximately 1,100 students, 75 teachers, and a diverse student population that is 60% Hispanic and 18% African American. The evaluation aims to understand the factors influencing students' collaborative experiences and teachers' perceptions of the program's effectiveness. Data collection involves surveys with closed and open-ended questions administered to teachers, as well as interviews with school administrators about the program's goals and implementation. Emerging themes from interviews include the importance of experienced teachers and the diversity of the district. The evaluation will inform decisions about expanding the program to more schools.
