My study contributes to the literature that examines diverse issues pushing back on and expanding Social and Emotional Education in elementary school contexts. Schools and educational institutions require more attention and responsibility to promote students' social, emotional, and relational lives. In my dissertation, I paid particular attention…

This study focused on what values teachers saw in nature-based learning, what outcomes they saw for their students, and what factors have enabled them to do nature-based learning. This explanatory sequential mixed-methods study looked at nature-based learning in St. Louis elementary schools with kindergarten through second-grade students. We used…

This study focused on the effect of fifteen minutes of direct phonics instruction three days per week on student achievement, of Winter MAP goals, during the Response to Intervention block, during English language arts class. The literature suggests the use of both systematic and word-based strategies for instructional strategies, more scientific…

This convergent mixed methods study examined six principals' literacy leadership practices and student literacy achievement in first grade. This study utilized TPRI data from the 2018-2019 school year and qualitative data from principal interviews from the same school year. Participants in this study included 354 first grade students and six…

Student diversity in public education facilities and socioeconomic situations has led to students in elementary schools entering kindergarten less prepared than in previous generations. This has resulted in educators searching for new strategies to motivate students and increase academic achievement. The problem addressed in this study is that…

I designed an explanatory sequential mixed-method study to explore the relationship between leadership practices, collective teacher efficacy (CTE), and educational outcomes of low SES students in an open school system. Four data sources were analyzed: K-5 student Developmental Reading Assessment (DRA) results of 1,170 students, Collective Teacher…

An important subgroup of English learner-classified (EL) students immigrate to the U.S., entering U.S. schools upon their arrival. Using growth models and statewide data, this study asks first, how newcomers' English proficiency status and growth compare to those of non-newcomer EL students; and second, what characteristics are associated with…

The COVID-19 pandemic has been a seismic and ongoing disruption to K-12 schooling. Using test scores from 5.4 million U.S. students in Grades 3-8, we tracked changes in math and reading achievement across the first 2 years of the pandemic. Average math test scores in the fall of 2021 in Grades 3-8 were 0.20-0.27 standard deviation (SD) lower…

This study explores the relationship between play-based learning and achievement in mathematics in Palestinian elementary school children. Forty teachers from eight schools received training in play-based pedagogies and follow-up support visits from programme staff (intervention group); four matched schools served as the control group.…

In this paper, we explore the early indicators of design fixation occurring during the concept development stage of children's design processes. This type of fixation, which we named: "concept fixation," causes a blind adherence to the current (possibly unfavourable) state of a design idea. Its occurrence hampers the creative thinking…

The language and concepts used by curriculum designers are not always interpreted by children as designers intended. This can be problematic when researchers use self-reported survey instruments in concert with curricula, which often rely on the implicit belief that students' understanding aligns with their own. We report on our refinement of a…

This paper introduces a new mode of variational and covariational reasoning, which we call scaling-continuous reasoning. Scaling-continuous reasoning entails (a) imagining a variable taking on all values on the continuum at any scale, (b) understanding that there is no scale at which the continuum becomes discrete, and (c) re-scaling to any…

Subitizing, a quick apprehension of the numerosity of a small set of items, has been found to explain students' number understanding when counting. We utilized a constructivist teaching experiment methodology to investigate how the counting and subitizing activity of one student, Diego, related to his number understanding (described by his…

In all educational levels, teachers assign their students with different activities to practice and reinforce what they have learnt. Further, assignments are valuable educational tools that raise students' consciousness as believed by teachers, parents, and authorities. It functions, in a sense, as a bridge between schools and homes. Assignments…
