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…

This quantitative, correlational study aimed to investigate the relationships between collective teacher efficacy (CTE), its enabling conditions (EC-CTE), and student achievement in third through eighth grades in Colorado. Leveraging the theoretical foundations established by Rotter (1954), Bandura (1977) and expanded by Tschannen-Moran et al.…

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.…

Teacher evaluation systems treat instructional quality as generic. Principals often observe elementary teachers in one subject and generalize assessments to all subjects. However, there is little empirical work to justify these decisions. This study provides needed evidence about whether elementary teachers engage in comparable instruction across…

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…

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…

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,…

This study examines the use of cross-classified random effects models (CCrem) and cross-classified multiple membership random effects models (CCMMrem) to model rater bias and estimate teacher effectiveness. Effect estimates are compared using CTT versus item response theory (IRT) scaling methods and three models (i.e., conventional multilevel…

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…
