This study is a randomized control trial of full- versus half-day prekindergarten (pre-K) in a school district near Denver, Colorado. Four-year-old children were randomly assigned an offer of half-day (4 days/week) or full-day (5 days/week) pre-K that increased class time by 600 hours. The full-day pre-K offer produced substantial, positive…

The Good Behavior Game (GBG, Barrish, Saunders, & Wolf, 1969) and the PATHS Curriculum (Promoting Alternative Thinking Strategies; Greenberg, Kusche, Cook, & Quamma, 1995) represent 2 universal, elementary school, preventive interventions which have been shown in large-scale, randomized controlled trials to have an immediate and beneficial…

Problem/Purpose: Young children with developmental speech and/or language impairment (DSLI) often fail to develop important oral language and early literacy skills that are foundational for subsequent schooling and reading success. The purpose of this investigation was to examine the efficacy of the TELL curriculum and associated evidence-based…

Mission HydroSci (MHS) is a 3D game-based learning environment and curriculum that supports middle school student learning of water systems science and scientific argumentation. MHS is a rigorous, coherent and engaging 6 to 8-day curriculum with all learning activities and social interactions taking place in the virtual world and with teachers…

In 2011, the University of Alaska Fairbanks (UAF) received an Investing in Innovation (i3) Grant through the U.S. Department of Education. UAF applied for the grant to expand the predominantly rural-serving Alaska Statewide Mentor Project (ASMP) to urban settings. ASMP is a professional development initiative that supplies fully released, highly…

The goal of this randomized controlled trial (RCT) was to evaluate the effectiveness of a small-group intervention in fractions for fifth-graders who are performing below grade level in mathematics. The impact of the fractions intervention was assessed on fifth-grade at-risk students' understanding of foundational fractions concepts and procedural…

The purpose of this study was to examine the impact of the Florida Master Teacher Initiative (FMTI)--an i3-funded early learning program aimed at improving the quality of teaching and student outcomes in grades PreK through third grade in high need schools. The FMTI schools participated in four program components: (1) a job-embedded graduate…

Students' beliefs that success in science depends on exceptional talent negatively impact their motivation to learn. For example, such beliefs have been shown to be a major factor steering students away from taking science and math courses in high school and college. In the present study, we tested a novel story-based instruction that models how…

This study evaluated an approach to professional development for middle school science teachers by closely examining one grade 8 course that embodies that approach. Using a cluster-randomized experimental design, the study tested the effectiveness of the Making Sense of SCIENCE[TM] professional development course on force and motion (Daehler,…

The study examined in this review analyzed whether a full two-year "Learning Experiences and Alternative Program for Preschoolers and Their Parents" ("LEAP") training and support model for teachers was superior in improving outcomes of preschool children with Autism Spectrum Disorder (ASD), as compared to a limited…

Researchers have demonstrated that cognitive-behavioral intervention strategies--such as social problem solving--provided in school settings can help ameliorate the developmental risk for emotional and behavioral difficulties. In this study, we report the results of a randomized controlled trial of Tools for Getting Along (TFGA), a social…

State education departments, in discussions with Regional Educational Laboratory (REL) Southeast, identified low reading achievement as a critical issue for their students and expressed an interest in identifying effective strategies to promote the foundational skills in young students that might improve reading achievement. The Mississippi…

Background: A key learning outcome in problem-solving domains is the development of procedural flexibility, where learners know multiple procedures and use them appropriately to solve a range of problems (e.g., Verschaffel, Luwel, Torbeyns, & Van Dooren, 2009). However, students often fail to become flexible problem solvers in mathematics. To…

A variety of preschool curricula is available and in widespread use, however, there is a lack of evidence from rigorous evaluations regarding the effects of these curricula on children's school readiness. The lack of such information is important as early childhood center-based programs have been a major, sometimes the sole, component of a number…

This study examines whether the Problem Based Economics curriculum developed by the Buck Institute for Education improves grade 12 students' content knowledge as measured by the Test of Economic Literacy, a test refined by the National Council on Economic Education (NCEE) over decades. Students' problem-solving skills in economics were also…
