We discuss an original study and two replications conducted over 18 years examining the impact of Teacher Study Group (TSG) in Vocabulary, a professional development (PD) approach for improving pedagogy and student learning. Study 1 focused on the design and development of the PD and included a small-scale randomized controlled trial to assess the…

The paper presents an analysis of elementary grade mathematics teaching in India focusing on mathematical reasoning. Mathematical reasoning is an important tool to make sense of mathematical ideas, which in turn makes mathematics more accessible to learners and promotes social equality. The paper analyzes 112 lessons from Grades 1 to 8 by 21…

E-learning platforms have become increasingly popular in K--8 education to promote student learning and enhance classroom teaching. Student interactions with these platforms produce trace data, which are digital records of learning processes. Although trace data have been effective in identifying learners' engagement profiles in higher education…

Theoretical perspectives within disciplinary fields are often characterized by initially dichotomous frameworks that become more integrative over time. Indeed, popular discourse on the Science of Reading emphasizes dichotomous contributions of word reading and language comprehension to reading. Yet, these skill sets are inherently complex,…

The impact of the International Baccalaureate (IB) curriculum on Chinese teachers' self-efficacy has been unknown. The purpose of this causal-comparative study was to determine the impacts of the International Baccalaureate curriculum on Chinese teachers' reports of self-efficacy. Two groups were studied, the first comprised Chinese public…

The purpose of this longitudinal study was to critically evaluate the updated Turkish reading curricula to determine whether they enable teachers to design instructional sequences that are highly cognitively demanding. This study was designed as a qualitative inquiry using document analysis to estimate the pedagogically oriented intellectual…

Public school board members are charged with the responsibility and accountability to provide governance-level advocacy for equity and excellence in public education. This qualitative study examined the perceptions of school board members in three K--8 school districts in the midwestern part of the United States regarding the 50+ year Race-Based…

Interpreting change in Body mass index (BMI) among youth by comparison to growth charts can be difficult because of maturation-related changes. The aim of this paper was to evaluate the utility of several alternative methods for assessing change in BMI among children. Participants included 1,615 children measured for stature and body mass in first…

There is a lack of research on students' conceptions of giftedness and intelligence, despite recognition of their influence on real-life factors such as achievement and motivation. This paper presents a cross-sectional mixed methods study that investigated Finnish students' (age 6-16 years; N = 1282) implicit conceptions of giftedness and…

Background/Context: The age at which children can enter kindergarten continues to be discussed in both educational research and practice, and the debate for whether to increase kindergarten entry age remains active on both sides. A critical oversight has been the lack of attention paid towards entry age for those students who begin school with a…

Background: The association between early childhood psychosocial problems and poorer educational outcomes is well-documented, but the extent to which this association persists is less understood. The current study assessed the correlations between first-grade psychosocial functioning and educational outcomes through eighth grade in a large…

This study explores the impact of professional learning communities on student achievement in a small school setting. Aaron Hansen's book, "How to Develop PLCs for Singletons and Small Schools," offered a guide for arranging vertical, grade-level teams with one teacher per grade level at one private, K-8 school. The faculty engaged in…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

Academic underachievement, as measured on standardised assessments, is commonly reported among students on the autism spectrum. However, little is known about the factors that predict academic (under)achievement, limiting the development of effective and targeted interventions. This study explored teacher ratings of academic skills and enabling…

Mathematics classrooms in which students engage in argumentation constitute a favourable context to analyse how teachers recognize and incorporate student contingencies. Through exploratory case studies, we examined three mathematics lessons in which teachers support argumentation in contingent situations triggered by student errors. Teachers'…
