GeoGebra represents a significant advancement in educational technology, providing dynamic tools for mathematics education. However, its specific impact on student motivation and achievement in geometry remains understudied. This research investigates the effects of integrating geometrical design through GeoGebra on these outcomes. Conducted over…

Over the last 20 years, many methods have been proposed to use process data (e.g., response time) to detect changes in engagement during the test-taking process. However, many of these methods were developed and evaluated in highly similar testing contexts: 30 or more single-select multiple-choice items presented in a linear, fixed sequence in…

This research is motivated by observations that show the lack of additional teaching materials in schools that facilitate students in communicating mathematical ideas (symbols, pictures, and graphs) as well as concepts related to fractions by presenting the surrounding environment as a source of learning. The purpose of this study is to reveal the…

The aim of this study was to investigate the correlation between culturally relevant Black American-sounding names and potential racial microaggressions within problem-solving scenarios in mathematics. Often, marginalized groups are unfairly characterized in society, leading to biased perceptions. Initially, I hypothesized that there would be no…

Uncertainties are inherent in education as learners encounter gaps in their awareness of topics, receive new information that potentially conflicts with prior understandings, and grapple with known unknowns in order to construct new knowledge. While researchers have shown that students productively struggling with problematized and uncertain…

This study extends prior research by manipulating both intervention and skill difficulty using a multiple baseline across participants design with changing phases in a virtual tutoring environment. Participants were four U.S. students from third and fifth grades for whom appropriate and challenging instructional targets were selected following…

A school's emphasis on academic success (SEAS) is a crucial aspect of school climate that can be rated by different informants, such as teachers or principals, and with respect to their perception of different groups' emphasis on academic success, such as parents or students. We know little about whether there is agreement between these ratings.…

This study explored the role of secondary Mathematics teachers' characteristics and multi-dimensional beliefs in integrating technology into teaching practice (i.e., mode of technology use). The research design employed is the convergent mixed method. The quantitative strand employed an electronic survey with 83 respondents. It has one primary…

The aim of this study is to explore the possibility of introducing the general notions of function and inverse function through a mathematical activity on linear functions, focusing on the quantitative meaning associated to the connection between a relation and its inverse. We present a genetic decomposition, that is, a viable cognitive path for…

This study explored the potential connections between secondary in-service (ISTs) and preservice (PSTs) mathematics teachers' anticipations and their noticing of student thinking in technology-mediated learning environments, a topic with limited prior research. Specifically, the study examined how teachers (ISTs and PSTs) anticipate student…

This study investigated the effects of working memory load (WML) and automaticity on mental addition through an examination of both task and individual characteristics within the framework of cognitive load theory. Results from 73 fourth graders showed that WML, automaticity, and their interaction had significant effects on mental addition.…

Conceptual replications are part and parcel of education science. Methodologically rigorous conceptual replication studies permit researchers to test and strengthen the generalizability of a study's initial findings. The current conceptual replication sought to replicate the efficacy of a small-group, first-grade mathematics intervention with 240…

Understanding exponential growth is a fundamental aspect of developing critical numeracy skills; however, typically, exponential growth is introduced in curricular documents to secondary students. Moreover, such introductions tend to be in the context of formal mathematical modeling, divorced from a sense of quantity. The authors argue that, given…

This study explored the use of Indigenous storytelling in the planning and teaching of mathematical content. In collaboration with Indigenous and non-Indigenous educators, a culturally inclusive mathematical lesson was developed, implemented, and reviewed in an elementary school in Northern Ontario. This study used a culturally authentic approach…

A common approach to scaling up a professional development program is for the researchers who designed the program to prepare teacher leaders to facilitate it at their schools. When researchers eventually leave, however, teacher leaders may receive less support. To ensure that teacher leaders continue receiving support, researchers can prepare…
