Understanding digital supports for early learning is paramount for school readiness and later mathematics learning. We present results from a randomized control trial evaluating a digital app (Measure Up!) and a parent companion app (Super Vision) designed to teach children measurement concepts, a skill that many teachers do not feel comfortable…

With this dissertation I present a self-narrative autoethnography to share the pedagogical practices that have been found to be successful in the academic achievement of mathematics with a specific sector of Students of Color, Black/African American students, in the urban inner-city schools. A combination of self reflected teaching experiences in…

This study offers a view on students' technology-based problem solving activity through the lens of a theoretical model which accounts for the relationship between mathematical and technological knowledge in successful problem solving. This study takes a qualitative approach building on the work of a 13-year-old girl as an exemplary case of the…

The purpose of this study is to examine 8th grade students' skills of connecting mathematics to real life. This study uses survey design since it aims to determine existing situations regarding to students' skills of connecting mathematics to real life. The study sample consists of 176 students in total, who are studying at a state school in the…

Computer scientists are working on reproducing all human skills using artificial intelligence, machine learning and robotics. Unsurprisingly then, many people worry that these advances will dramatically change work skills in the years ahead and perhaps leave many workers unemployable. This report develops a new approach to understanding these…

In this paper, we identify, from historical vantage points, the following six purposes of school algebra: (a) algebra as a body of knowledge essential to higher mathematical and scientific studies, (b) algebra as generalised arithmetic, (c) algebra as a prerequisite for entry to higher studies, (d) algebra as offering a language and set of…

Computational fluency is composed of three components: efficiency, mathematical flexibility, and conceptual understanding. Although research highlights the importance of all three of these components in mathematical understanding, a majority of assessments primarily focus on efficiency. In this paper, we propose a novel way of measuring and…

In this paper, we explore algebra students' mathematical realities around fractions and division, and the ways in which students reinvented mathematical productions involving fractions and division. We find that algebra students' initial realities do not include the fraction-as-quotient sub-construct. This can be problematic because in algebra,…

Although counting problems are easy to state and provide rich, accessible problem-solving situations, there is much evidence that students struggle with solving counting problems correctly. With combinatorics (and the study of counting problems) becoming increasingly prevalent in K-12 and undergraduate curricula, there is a need for researchers to…

The incorporation of prerequisite skill structures into educational systems helps to identify the order in which concepts should be presented to students to optimize student achievement. Many skills have a causal relationship in which one skill must be presented before another, indicating a strong skill relationship. Knowing this relationship can…

Research exploring how Hispanic-Serving Institutions (HSIs) serve Latin* STEM students has largely focused on features of organizational structures (e.g., support programs), but minimally examined instruction and classroom experiences. This is an important gap to fill, especially in gateway mathematics courses, where faculty relationships and…

Developmental Coordination Disorder (DCD) and Attention Deficit Hyperactivity Disorder (ADHD) often co-occur and are associated with specific learning difficulties. Robust prevalence estimations do not yet exist. We studied how symptoms of DCD and/or ADHD are related to difficulties in reading, writing, and mathematics. Using the data from a large…

This study aims to reveal the problems faced by a dyslexic student in learning science and determine what can be considered an effective science teaching method for this kind of learner. The case study design was used, and the study was conducted with a 7th-grade dyslexic female student. This study used observations and a semi-structured interview…

There have been increasing concerns about the significant decline in teenagers' intentions to pursue STEM subjects or careers. This study examined how students' perceptions of parental expectations, STEM cultural capital, mathematics/science self-efficacy, gender, and parents' jobs were associated with STEM career aspirations and tested whether…

Research Findings: This study examines the development of problem behavior in classroom contexts characterized by peer interaction among a nationally representative sample (N = 3,827) of U.S. low-income children from preschool entry to first grade. Latent growth mixture modeling was employed to identify unobserved subpopulations (latent classes)…
