Today my guest is Dr. Henry May  who has studied the popular first grade intervention Reading Recovery. We discuss results of two robust studies he was involved in—one showing strong positive effects in first grade, and another showing students who received the intervention underperformed years later on their third and fourth grade tests. We discuss why that might be, and what lessons we can learn about short term and ongoing interventions, as well as the ways that reading needs change and develop across grades K-4. Later, I’m joined by my colleagues Gina Dignon and Macie Kerbs for a conversation about practical takeaways.  *** To read a transcript of this episode and learn more about the show, visit jenniferserravallo.com/podcast.  *** About this episode’s guest: Henry May, PhD, is Director of the Center for Research in Education and Social Policy(CRESP) and Associate Professor specializing in Evaluation, Measurement, and Statistics in the School of Education at the University of Delaware.  Dr. May is the Principal Investigator (PI) with Elizabeth Farley-Ripple for the Institute of Education Sciences (IES)-funded Center for Research Use in Education, which is currently conducting a large-scale mixed methods study of how and when schools use research and how researchers strive to connect their work with practice.
