Background and objectives: An early understanding of numerosity is crucial to developing proficiency in arithmetic, and rapid pattern recognition via subitizing is key in this process. The training app "LORE" specifically targets and cultivates pattern recognition skills from the beginning of formal schooling. This study investigated…

Training teachers in evidence-based practice is a societal challenge. We conducted practical action research to investigate the impact of a professional development programme (the aim of which is to train teachers in explicit instruction) established according to the principles of effective professional development on one teacher's practices. A…

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…

Information about program implementation provides critical information for the interpretation of results from randomized trials. The present study provides an evaluation of the implementation of a Cognitively Guided Instruction mathematics teacher professional development as part of a large scale randomized controlled trial with teachers in first-…

Teachers' noticing of students' mathematical thinking plays an important role in supporting student learning. Yet little is known about how online professional development (PD)--a growing setting for PD in the USA--can cultivate this noticing. Here, we explore the potential of using two online tools for engaging video to support K-2 teachers'…

Purpose: The aim of the study is to better understand how lesson study (LS) contributes to challenging teachers' views of mathematics teaching and learning. Design/methodology/approach: This study is part of a wider ongoing project aiming at improving primary mathematics teaching in Malawi through professional development (PD) of teachers using a…

Teachers are essential in ensuring children and society are aware of neurodiversity by actively incorporating inclusive children's literature into their classroom activities to promote understanding and acceptance of neurodiverse individuals. Integrating such literature may enhance children's awareness and acceptance of neurodiverse individuals.…

In a study examining the efficacy of Heggerty's Bridge to Reading program during the 2023-2024 school year, LXD Research measured the program's impact on kindergarten and first-grade students' reading outcomes on the NWEA MAP Reading Fluency assessment. Results indicated that first graders using the program demonstrated significantly greater…

This national implementation study aimed to evaluate the effectiveness of Tier 2 structured literacy teaching set within a multi-tiered system of support. Case-controlled matching was used to determine the impact of the implementation for 1,265 5-year-old children. One comparison group included 1,265 children who were matched to the experimental…

While coaching is a well-documented form of professional development to support teachers' instructional practices in mathematics, limited research exists on how coaches can support teachers in differentiating their mathematics instruction. Hence, as part of this retrospective case study, we explored how one instructional coach leveraged a coaching…

This study examined a professional development (PD) intervention that provided kindergarten-through third-grade teachers with drama-based pedagogy to improve student reading achievement. The PD consisted of collaboration between teaching artists and teachers to integrate drama into English language arts instruction for a school year. Twenty-six…

There is growing recognition that mathematical modeling can be a lever for equity in elementary mathematics classrooms. This study focuses on the impact of a professional development program focused on culturally responsive mathematical modeling on 8 kindergarten through 2nd grade teachers' practices in modeling lessons. We use a project developed…

This case study explores the impact of a thinking-based teacher training and professional development programme on the quality of classroom interactions and on students' metacognitive capacity in early childhood education and elementary first-grade classrooms. The study was conducted in a Spanish school, and the sample comprised 13 educators and…

Current models of education are less effective at developing the skills needed for individuals to thrive in this Information Age and beyond. One way to adapt education for current times is through what the authors call Active Playful Learning (APL), a pedagogical framework that is evidence-based, practical, and uniquely co-designed with scientists…

When language is defined narrowly in mathematics classrooms, racially and linguistically minoritized students in classrooms could be systematically positioned as "learners of deficiency." Recent scholarship calls for expanding the notion of language to emphasize embodied expression of mathematical ideas. Taking a critical perspective to…
