A child's home environment has been shown to be related to the development of early numeracy skills in some countries. However, significant relationships between home learning environment and math achievement have not consistently been found, and likely vary across different cultural and socio-political contexts. Here we explored the home…

Techno-mathematical Literacies (TmL), which are defined as a combination of mathematical, workplace and ICT knowledge, and communicative skills, are acknowledged as important learning goals in STEM education. Still, much remains unknown about ways to address them in teaching and to assess their development. To investigate this, we designed and…

Research has shown that computational thinking and kindergarten mathematics instruction can be integrated; however, evidence of how specific mathematical knowledge relates to computational thinking remains scarce. Additionally, we do not know if and how children's mathematical knowledge co-occurs with computational thinking and how these…

To stay up with society and technology, pedagogical changes are needed. Even a well-designed curriculum depends on teachers, who implement it. Knowledge drives this field's educators' actions. This dissertation examined how the Southwest New Mexico Elementary Mathematics Specialists (EMS) program affects elementary mathematics teachers' PCK.…

The purpose of this multiple case study was to explore affordances for STEM-related skills in a nature preschool in central Texas. Observations were conducted along with the collection of videos and photographs of four preschool-aged participants. Informal interviews were also implemented during data collection and observations. Semi-formal…

The development of early numeracy skills in preschoolers is an important predictor of future academic performance. A multiplicity of tasks or tests measure early numeracy skills in the English-language. Nevertheless, no tools are currently in French for evaluating and monitoring the development of young children's early numeracy skills. The…

I investigated the relationships between mathematics achievement on the Iowa Assessments and the mastery of four epistemic actions: selecting, analyzing, computing, and representing. These epistemic actions play a crucial role in characterizing mathematical reasoning and are essential for solving mathematics problems in the Iowa Assessments across…

Understanding fraction as a quantity has been identified as a key developmental understanding. In this study, students in Grades 5, 8, and 11 were asked to compare the areas of two halves of the same square--a rectangle and a right triangle. Findings from this study suggest that students who understand fraction as a quantity use reasoning related…

Numerous national and state endeavors have advocated for approaches, funding, and programs focused on expanding the science, technology, engineering, and mathematics (STEM) workforce of the nation and investing in education to cultivate a more diverse and impactful cohort of students who pursue STEM pathways. Educators, support personnel, and…

The post-pandemic return to school posed many challenges for educational leaders. Administrative teams had to come up with plans to close achievement gaps created by an extended period of remote learning. One suburban New Jersey high school identified at-risk students and created an Academic Mentoring Support (AMS) program as an intervention. Once…

Fractions are an integral part of the mathematics curriculum. Most students acquire proficiency with these concepts during the course of their elementary education and are usually able to perform basic fractions operations when reaching middle-school age. However, a considerable number of students require extra help to not fall further and further…

A systematic review of the literature (1965-2022) and meta-analysis were undertaken to compare the school readiness skills of children participating in public pre-kindergarten (pre-K) or Head Start. Seven quasi-experimental studies met the inclusion criteria for the meta-analysis and 38 effect sizes were analyzed. Results indicated no reliable…

The early childhood learning trajectories provide a translation of evidence on how children develop, incorporated into a clear, engaging resource for early childhood teachers and educators. This report summarises the evidence base that informed their development. It aims to deepen understanding of the domains of learning and development that the…

This study investigated differences between students' multiplication fact automaticity scores and student competencies on five problems from Intermediate Algebra assessments with a sample of university students. The five types of problems were: (1) linear equations with fractions, (2) system of linear equations, (3) factor by grouping, (4)…

The purpose of the present research is defining the direction and level of the relationship between 8th grade students' translating among multiple representations skills and their algebraic reasoning and revealing the predictive power on algebraic reasoning. The research was conducted in accordance with relational survey model, which is a…
