We are developing an approach to teaching important proportionality-based concepts to first grade students in a way that supports students' future progress in the domain. We consider the proportionality between magnitudes as a basic relationship behind multiple cases, usually described mathematically as ratio or rate. The core of our strategy is…

This research investigates the potential for a one-to-one coaching tool used by adults other than teachers to be able to deliver greater mathematics progress for primary school children without adding significantly to school costs. Plus 1 and Power of 2 (+1 and Po2) are workbooks designed to be used by adults other than teachers working on a…

Educators and policymakers advocate for the implementation of problem-based approaches to STEM education in K-12 classrooms to help students develop 21st-century skills such as the ability to think critically, collaborate, and problem-solve. The first exploratory case study in this three-article dissertation examines how students engage in…

For many years, mathematics research has focused on finding ways to help students improve their math performance. These efforts have led to the conclusion that building a strong mathematics foundation is associated with greater achievement across time. Students who develop number sense and learn to use efficient strategies at an early age are more…

This study explores the resilience of preschool and elementary school teachers (ISCED Level 1) in the Czech Republic. The data were gathered from a sample of 476 preschool teachers and 193 elementary school teachers using The Sense of Coherence Scale, a 29-item measure developed by Antonovsky. This scale consists of three dimensions, specifically…

In 2019, Poland experienced a massive teachers' strike that lasted three weeks. Although the strike had a great impact on many teachers, in the end, this three-week action failed to obtain any of its demands. Using the concepts of workers' associational power and union legitimacy, I argue that one of the reasons for the loss was a crisis of…

This empirical study examined how subjective norms (SNs) and perceived severity affected teachers' intention to intervene and their intervention behaviors in real-life bullying incidents in primary and secondary schools. A total of 362 teachers who witnessed or were told about bullying incidents participated in this study by completing related…

The Calm Cat Program was developed in response to the need for intervention approaches that target internalizing symptoms, are developmentally appropriate for early elementary students, and are feasible for school-based implementation by staff without specialized training. The Calm Cat Program is a brief Tier 2 intervention combining behavioral…

Research has demonstrated the positive effects of systematically teaching phonemic awareness and phonics in kindergarten and first grade, but many commonly used reading curricula do not adequately incorporate these foundational skills. In this study, we examined the efficacy of an instructional program ("UFLI Foundations") in…

Using a cluster randomized trial, we investigated the effects of mathematics professional development on student achievement in elementary schools. Pairs of schools were matched on prior mathematics; percentage of students receiving free or reduced-price lunch and percentage of limited English proficient students were randomly assigned to two…

This study aimed to examine language at the teacher/classroom level among second-grade classrooms that differ in socioeconomic backgrounds. Measures of teachers' vocabulary input across the school day throughout the school year were examined. There was a significant difference in the proportion of academic word use between classes that differed in…

Existing computational thinking (CT) research focuses on programming in K-12 education; however, there are challenges in introducing it into the formal disciplines. Therefore, we propose the introduction of non-programming plugged learning in mathematics to develop students' CT. The research and teaching teams collaborated to develop an…

Contemporary science education frameworks identify computational thinking as an essential science and engineering practice that supports scientific sense-making and engineering design. Despite national emphasis on teaching science, engineering, and computational thinking (NGSS Lead States, 2013), little research has investigated the ways that…

Despite the temperate climate, surrounded by pristine oceans, children in the Maldives do not meet the minimum daily physical activity (PA) requirements. Maldives is a resource inhibited country within the Indian rim. Generalist teachers are required to deliver primary physical education (PE). There is a paucity of information about Maldivian PE,…

Treatment integrity is critical to realizing the effects of evidence-based programs and practices (EBPPs) that aim to promote student mental and behavioral health. Across disciplines, time is consistently referenced as one of the most significant barriers to successful implementation outcomes (e.g., treatment integrity) of EBPPs. However, there is…
