Hezel Associates, PBS TeacherLine's external evaluator, implemented an evaluation strategy that employs a mix of quantitative and qualitative methods, including an experimental study, an expert review, a content analysis, and pre- and post-participation surveys.
The evaluation of PBS TeacherLine's next-generation services combine intensive studies of its integration within local teacher professional development efforts at multiple levels, with analyses derived through scientifically-based experimental research that meets What Works Clearinghouse standards. The research design strengthens PBS's ability to transform professional development by addressing foundational issues surrounding teacher professional development.
Dedicated to information sharing, Hezel Associates sees dissemination as a way to expand the research field's collective understanding of professional development, technology integration, and experimental methods. Therefore, the results of their research will be shared with researchers with shared interests, learning about other ways to conduct experimental studies to measure impact, and meeting with the education officials who ultimately will make the decision to host the research, Hezel Associates will optimize their ability to carry out the proposed series of studies.
