It is widely understood that preschool should provide children the mathematical foundational skills necessary for later success. This study examines seven preschool teachers and their use of a variety of pedagogical strategies to develop foundational mathematics concepts. Using a qualitative research design, this study uses the CLassroom…

Studies show that early engagement with mathematics leads to increased math achievement later in life. Yet, early childhood teachers do not regard mathematics as critical to young learners' development and lack confidence with helping children learn mathematics. Early childhood teacher comfort and engagement with mathematics is a critical element…

Research focused on emotionally supportive teaching has typically run in parallel to the study of rigorous, standards-aligned mathematics teaching. However, recent work theorizes that positive and warm classroom environments may be necessary to help students meet the ambitious goals outlined in newer mathematics standards. We analyze the…

Research Findings: A total of 54 videotaped mathematics activity observations drawn from 27 different pre-kindergarten classrooms in an urban public schools system in the U.S. were coded using 2 observational measures: (1) a general measure, the Classroom Assessment Scoring System (CLASS); and (2) a math-specific measure, the High Impact…

Mathematics teachers' preteaching experiences as mathematics learners can affect their identity and practice in supporting their own students' learning and motivation in mathematics. However, little empirical data exist on teachers' formative experiences to guide these assumptions, particularly how teachers draw on these experiences when teaching,…

Policy and practice communities increasingly are emphasizing conceptual, cognitively demanding, and "ambitious" instruction. Within this context, we examine whether such practices serve the needs of students with specialized academic needs. Across upper-elementary classrooms in four districts, we find that exposure to…

Latent classes of effective and non-effective Algebra I teachers were established using measurements of teacher promoted engagement, teacher promoted understanding, and classroom management from the Measures of Effective Teaching Project (MET Project) database. Historically, robust measures of effective teaching exist in the literature; however,…

An important challenge in evaluating the quality of teaching is to arrive at valid distinctions between teachers, particularly in the middle of the performance distribution. This study addressed this issue for the Chilean national teacher evaluation system. Mathematics teachers (N = 51) from the 2 middle adjacent performance categories, and their…

This paper introduces the LIDO, or the Low-Inference Discourse Observation tool, that captures discourse moves produced by students and teachers in whole-classroom discussions. Coding methods are described, followed by analyses that explore validity of the LIDO through correlations among LIDO-coded discourse moves and between LIDO scores and…

Helping teachers become more effective in the classroom is a high priority for educators and policymakers. A growing body of evidence suggests that individualized coaching focused on general teaching practices can improve teachers' instruction and student achievement. However, little is known about the benefits of specific approaches to coaching,…

Helping teachers become more effective in the classroom is a high priority for school leaders and policymakers. This Study Highlights presents key findings from a study that examined a promising strategy for improving teachers' effectiveness: providing individualized coaching using videos of teachers' instruction for reflection, practice, and…

These are the appendices for the report "Study of Teacher Coaching Based on Classroom Videos: Impacts on Student Achievement and Teachers' Practices. Evaluation Report." This report examined a promising strategy for individualized coaching: professional coaches--rather than district or school staff--providing feedback to teachers based…

Research Findings: This study investigated teachers' Concept development (CD) strategy use in whole-group math teaching and its associations with children's higher-order thinking processes in 25 Chinese preschool math lessons. We utilized the CD dimension within the Classroom Assessment Scoring System (CLASS) to guide our exploration. CD…

Whole-school or whole-class programs designed to promote positive behavior can enhance the likelihood that effective teaching and learning occur for all students. This practice guide is intended to help elementary education educators, as well as school and district administrators and parents, implement and support effective prevention-focused…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This final report from the program's evaluation focuses on results from a five-year…
