Is instructional coaching effective? Educational administrators are asking that question as they make important decisions about how to invest limited school resources in ways that drive improvement.
Some recent research suggests we might be asking the wrong question. A long list of studies identified highly successful coaching models, yet two large-scale randomized experiments [study 1, study 2] found that coaching had no significant impact on student achievement. A more appropriate question, then, might be, Under what circumstances, in what contexts, and for whom is coaching effective?
One way to answer that question is through design-based research, in which researchers and practitioners work together in partnership to study not only what works, but why.
In a recent study published in the October 2018 issue of The Educational Forum, my co-authors and I describe an evaluation of a video-based instructional coaching model where coaches video record collaborating teachers’ instruction. Teachers and coaches then review the tapes independently and then come together to co-construct a goal related to student outcomes. Coaches help teachers identify practical strategies for reaching those goals and tracking progress along the way.
This coaching model represents the culmination of a 2-year design-based research project where we made small improvements to the model over time, based on input from those actually implementing the model. We worked closely with instructional coaches on implementing a new approach to coaching that emphasized the use of video and teacher-led goal setting. During the first semester of implementation, we collected data and interviewed teachers and coaches. We presented our findings to the coaches, who provided additional feedback about their experiences implementing the model. Through this process, we agreed on changes to the model, implemented the coaching model with a new set of teachers, and continued this cycle.
The end result of this process was a coaching model that values the input of teachers, foregrounds the role of teacher-led goal setting, provides coaches with a set of evidence-based teaching strategies that serve as tools for reaching goals, and relies on video to support both data collection and teacher reflection.
In our study, we found that the coaching model led to significant changes in instructional practice, which, in turn, led to increases in student engagement in the classroom.
This type of research, referred to as design-based research or improvement science, comes in part from the Carnegie Foundation for the Advancement of Teaching, the National Center on Scaling Up Effective Schools, and others, with support from the Institute of Education Science’s new research-practice partnership grants.
More than ever, researchers and policymakers are beginning to recognize that knowing what works in education is necessary, but not sufficient for leading continuous improvement. Like many educational programs, policies, or reforms, whether instructional coaching is effective will depend on context and local practices. If we continue to focus only on what works, we may lose a valuable opportunity to understand more deeply what drives continuous improvement in schools.
