Impact of CW-FIT on Student Appropriately Engaged Behavior in Two Co-Taught Middle School Classrooms

Middle schools bring considerable change for students, which can intensify risk for adverse middle school student experiences and performance. Yet, implementation of positive and proactive classroom-level strategies can improve student outcomes. However, middle school teachers may not have the repertoire to systemically implement such classroom-level strategies to fidelity, particularly in co-teaching arrangements. This U.S. study investigated the impact of a classroom-level interdependent group contingency model, Classwide FIT ( CW-FIT ) on middle school student behavior. Two single-case withdrawal designs were used to evaluate the effects across two co-taught middle school classrooms. Furthermore, teacher-selected modifications to the system were explored as well as teacher and student perceptions of social validity. Results indicated the intervention and intervention modifications improved student appropriately engaged behavior and demonstrated social validity. Limitations of the study and directions for future inquiry are presented.
