Overview of REDI Research

Phase 1: The Head Start REDI project began in 2002 with a randomized trial of curriculum and professional development components designed to enhance the impact of Head Start on child school readiness. Two domains of school readiness were targeted: 1) language development/emergent literacy skills, and 2) social-emotional competencies. The program produced improvements in teaching quality in REDI classrooms, including enhanced teacher language use, instructional support, and emotion coaching. Children who received REDI showed enhanced outcomes on measures of vocabulary, emergent literacy skills, social competence, and learning engagement, and reduced aggression at the end of the Head Start year. Sustained benefits were documented in kindergarten.

Phase 2: In 2008, a second REDI trial was initiated. A new sample of children attending Head Start REDI classrooms were randomly assigned to receive a complementary REDI home visiting program or “usual practice” Head Start home visiting. The REDI home visiting program promoted improvements in child social competence, self-directed learning, and academic competence in kindergarten.

Phase 3: In 2014, REDI received additional funding to extend these findings by conducting follow-up assessments with children who participated in the two trials to evaluate the long-term effects of the REDI classroom and home visiting program on child school adjustment.  Follow-up assessments will track participants in the original REDI classroom program as they navigate through high school (grades 9 and 11) to test the hypothesis that the improved social-emotional functioning and self-regulation skills promoted by REDI will mediate long-term effects on academic attainment and reductions in risky behaviors in adolescence.  Follow-up assessments will also track the participants in the REDI home visiting program as they navigate the middle school transition (grades 5 and 7), testing the hypothesis that early improvements in parent support and academic school readiness will mediate program effects on later child outcomes.

Phase 4: In 2015, REDI received additional funding to create and evaluate a sustainable, technology-assisted platform of professional development support to facilitate the broad diffusion of the REDI program in preschools and child care centers. A collaboration was established with the Better Kid Care Program (BKC), managed by Cooperative Extension at Penn State.  Over a four-year period, we will work with 72 child-care centers in 7 economically stressed counties in Pennsylvania to evaluate REDI with professional development delivered using the technology-assisted distance learning platform of BKC will be used to extend professional development support. Classroom teachers will be able to access brief tutorials with videos demonstrating how to deliver lessons and illustrating high-quality teaching practices. In addition, the BKC platform will be used to support virtual learning communities of child-care center directors, who will be trained to monitor the fidelity of program implementation and coach teachers in the application of the curriculum components and teaching strategies. The evaluation will use a rigorous, randomized-controlled design, with multi-method measurement of child and teacher outcomes; it will assess short-term sustainability in the child care centers and follow children as they transition to kindergarten.
