Hertberg-Davis, H. L., & Brighton, C. M. (2006). Support and sabotage: Principals' influence on middle school teachers' responses to differentiation. The Journal of Secondary Gifted Education, 17(2), 90-102.
This study sought to understand the relationship between principals’ attitudes toward differentiation and middle school teachers’ willingness and ability to differentiate. Differentiation allows teachers to systematically address the needs of all learners, including gifted students, in diverse classrooms. The principals and faculty at three schools were interviewed and observed over the course of three years (1997-2000) as a subset of a larger study. Since the primary interests of this study were teacher-principal interactions, the meanings each group assigned to the process of adapting differentiated strategies, and teacher and principal perceptions of their own roles in the change process, the study was based on theories of interpretive sociology and incorporated several different qualitative data collection methods.
A principal’s attitude toward differentiation, level of support for the teachers, belief in and desire for change, and amount of focus on differentiation in particular played key roles in teachers’ willingness and ability to differentiate curriculum, instruction, and assessment in this study. The results suggest that successful implementation of differentiation is more likely when principals understand the importance of differentiation and provide the resources and emotional support faculty need to successfully integrate differentiation into their classrooms.
In the course of reviewing the literature relevant to this study, the authors note that the typical public school classroom contains 27 children whose academic performance levels typically span more than five grade levels. Despite recommendations for differentiated instruction, the most common techniques in middle school classrooms are still traditional lecture, drill-and-practice, heterogeneous cooperative learning groups, and direct instruction. As a result, understanding the factors behind implementing differentiation in classrooms is more important than ever. The authors make suggestions for a successful transition to differentiation strategies, as well as ideas for further research, including the impact of No Child Left Behind on attempts to implement differentiation.
Readers should note that although the authors took measures to increase the reliability of their data, only three schools were studied, each of which differed greatly from the others (teacher-principal relationships, socioeconomic status, geography, etc.), so more studies are needed to fully understand the effect of teacher-principal relationships on the effectiveness of implementation of differentiation in classrooms.
