My areas of expertise include student-teacher relationships and classroom processes that promote positive academic and social development for children. This work documents the ways in which teacher-child relationships are predictive of academic and social development and the ways in which exposure to effective classroom social and instructional interactions may help close the achievement gap for students at risk of school failure. With Drs. Robert Pianta and Karen La Paro, I authored an observational tool for classrooms called the Classroom Assessment Scoring System (CLASS). I lead efforts to use the CLASS as an assessment, accountability, and professional development tool in early childhood and other educational settings. I have recently worked with leaders in several states and the Office of Head Start to implement CLASS as a tool to enhance teacher-child interactions through accountability and professional development systems. Currently I am engaged in the development and testing of interventions designed to improve the quality of teachers’ interactions with students– including MyTeachingPartner coaching model and an online course developed for early childhood teachers. I am also very interested the ways implementation science can inform our ability to successfully deliver these types of interventions at large scale.
