A teacher expectation intervention: Modelling the practices of high expectation teachers

Abstract

Since the original Pygmalion study, there have been very few interventions in the teacher expectation field and none that have been randomized control trials designed to change teacher practices to reflect those of high expectation teachers. The current study was designed to address this gap in the literature. Teachers (N = 84) were randomly assigned to either intervention or control groups. Those in the intervention group attended four workshops at which were presented the instructional strategies and practices of high expectation teachers. At each workshop, the intervention group planned changed practices to introduce to their classrooms modelled on the behaviours of high expectation teachers. The researchers visited the teachers on three further occasions to ensure fidelity of the implementation. Students in the classes of the intervention group teachers significantly improved their mathematics achievement over one year, showing a rate of improvement beyond that shown by the students of the control group teachers. Teachers reported high levels of satisfaction with their changed practices and overall, there was a demonstrable degree of integrity in the implementation of the intervention as measured by the researchers. Practical guidelines in relation to the intervention and future directions of the project are included.
