Lesson study, especially when conducted with support from targeted resources, is often identified as a potentially effective means to support teacher learning. In this study, 80 school-based teams of educators, representing 80 classrooms of third- or fourth-grade students in the US, were randomly assigned to one of four conditions: lesson study…

Large numbers of U.S. students lack proficiency in science, and students from different racial/ethnic and socioeconomic groups show disparities in science achievement. Science knowledge and skills are important for both academic and workplace success, and a variety of interventions have been developed to improve student achievement in science.…

We examined the predictive value of early spelling for later reading performance by analyzing data from 970 U.S. children whose spelling was assessed in the summer following the completion of kindergarten (M age = 6 years; 3 months). The word reading performance of most of the children was then tested after the completion of Grade 1 (age 7;5),…

Modern behavior-genetic studies of twins in the United States, Australia, Scandinavia, and the United Kingdom show that genes account for most of the variance in children's reading ability by the end of the 1st year of formal reading instruction. Strong genetic influence continues across the grades, though the relevant genes vary for reading words…

This article describes the effects of an analysis-of-practice professional development (PD) program on elementary school students' (Grades 4-6) science outcomes. The study design was a cluster-randomized trial with an analysis sample of 77 schools, 144 teachers and 2,823 students. Forty-two schools were randomly assigned to treatment, (88.5 hours)…

Part of the Stanford Center for Opportunity Policy in Education (SCOPE) research series titled "Teachers' Time: Collaborating for Learning, Teaching, and Leading," this case study looks at Pagosa Springs Elementary School, which is located in the Town of Pagosa Springs, Colorado. The school serves students in kindergarten through fourth…

The authors describe an impact study of Classroom Assessment for Student Learning (CASL), a widely used professional development program in classroom and formative assessment. Researchers randomly assigned 67 elementary schools to receive CASL materials or continue with regularly scheduled professional development. Teachers in CASL schools formed…

Over a decade ago, Borko (2004) raised the awareness of the education research community to the critical need for studies of teacher professional development (PD) programs. She states on page 13: "My challenge to the educational research community is this: We have much work to do and many questions to answer in order to provide high-quality…

Twelve-month follow-up outcomes from a group-randomized trial (GRT) of a classroom curriculum aimed at preventing bullying and victimization among elementary students in the Denver, Colorado, public school system are presented. Twenty-eight elementary schools were randomly assigned to receive selected modules of "Youth Matters" (YM), a…

Two professional development (PD) models for teachers were compared on teacher and student outcomes. Special education teachers participated in Literacy Learning Cohorts (LLC), a PD innovation designed to improve content and pedagogical knowledge for providing reading instruction to upper elementary students with learning disabilities. The LLC,…

We examine a 4th grade teacher's development of a constructivist-based, adaptive pedagogy (AP) approach--and its contribution to student multiplicative reasoning and outcomes, mixing qualitative analysis of segments from her interviews with quantitative analysis of her student outcomes on the state-mandated test. Her reflections indicate a shift…

This study used a random assignment design to investigate the impact of "Classroom Assessment for Student Learning" ("CASL") on elementary students' mathematics achievement. A total of 67 schools across 32 Colorado school districts were randomly assigned to either an intervention condition that used "CASL" or a…

This study was conducted by the Central Region Educational Laboratory (REL Central) administered by Mid-continent Research for Education and Learning to provide educators and policymakers with rigorous evidence about the potential of Classroom Assessment for Student Learning (CASL) to improve student achievement. CASL is a widely used professional…
