Research Interests

My major research interest has been psychoeducational consultation (sometimes referred to as instructional coaching). Consultation in schools typically involves delivering targeted interventions to children and adolescents through staff members who serve as the direct change agents. For example, a school psychologist could consult with a teacher about a student or group of students, with the teacher then helping students directly with the psychologist’s assistance. The successful practice of consultation in schools has clear implications for preventing academic failure, promoting mental health, and providing a support system to staff members. Consultation is integral to contemporary methods of service delivery in schools, such as those found in problem-solving teams and multi-tiered systems of support.

I have examined interpersonal dynamics and participant outcomes associated with several recognized models of consultation. One research theme recognizes that, “what is said in consultation is important,” and thus involves coding recordings and transcripts of dyadic and small group interviews to link verbal interaction measures to various outcome measures. A second research theme involves studying interpersonal dynamics of consultation with respect to social influence, thereby allowing a glimpse into how a consultant may persuade a teacher (or vice versa). For instance, through their words and actions, consultants may influence teachers to implement interventions with a high degree of fidelity and thereby improve educational outcomes for children.

A third more recent theme involves the use of technology to deliver consultation services. One focus has been to see how comparable consultation sessions conducted remotely through videoconferencing are to those conducted in an in-person, face-to-face manner. Another focus has been to explore the use of telepresence robots to provide classroom observations and conduct school consultation. Given the realities of travel time and distance — as well as the current pandemic — serving as barriers to service provision, this technology-based research theme has a clear practical value.
