Patricia Vadasy, Ph.D., is a Senior Research Scientist at Oregon Research Institute. She has an extensive background in the acquisition of early alphabet and word reading skills, vocabulary instruction, and school-based intervention research. Patricia has been the principal investigator on eight United States Department of Education (DOE) funded projects, and co-investigator on three projects. She was the principal investigator on a series of research studies on supplemental early reading interventions. Patricia has published widely on her reading intervention research in peer-reviewed journals. She is the first author of the Sound Partners reading interventions (Vadasy et al., 2005; Vadasy, 2013), and co-author of Handbook of reading interventions (O’Connor & Vadasy, 2010).

Reviews of Published Research and Resources

The efficacy studies published by Patricia Vadasy and her colleagues have been reviewed by several panels of experts. The most extensive review was conducted by the Institute of Education Sciences’ What Works Clearinghouse (WWC). The WWC assesses the scientific merit of studies of the effectiveness of education interventions against WWC standards. The WWC website features a full report on the review, and a summary of major findings.

Research findings published by Vadasy and colleagues have also been reviewed by the National Center on Intensive Intervention, and by the Johns Hopkins University School of Education’s Center for Data-Driven Reform in Education, and published on their Best Evidence Encyclopedia website.

In fall, 2014 Voyager/Sopris, the publisher of the Sound Partners phonics interventions that were developed and evaluated in the efficacy studies conducted by Dr. Vadasy and her colleagues between 1993-2007 uploaded research summaries and training videos on their web pages. The videos are designed to help non-teacher tutors supplement early reading instruction in important beginning phonics skills and are hosted by Voyager/Sopris to help schools prepare tutors to supplement instruction in critical early reading skills for struggling students.
