This study aimed to assess and compare the development of mathematical procedures on the part of Grade 7 students using an intelligent tutoring system on a digital platform. The sample comprised 96 students from Khon Kaen University Demonstration School, Thailand, divided equally into experimental and control groups. The experimental group worked…

This paper focuses on a professional development program for lower-secondary school mathematics teachers, led by mathematics education researchers, based on historical insights from Fibonacci's Liber Abbaci. The program, involving 25 teachers, emphasized using the history of mathematics to craft meaningful mathematical lessons on the topic of…

Although curriculum materials are essential for implementing instructional innovations, little is known about how exactly they support teachers' enactment of innovative approaches and how explicitly they must integrate their key components. The paper contributes to reducing this research gap for one instructional innovation: explicit strategy…

In hard-to-staff subjects like secondary school mathematics, out-of-field teaching--where teachers are required to teach subjects outside their expertise--is a necessary reality. While strategic investments in continuous professional learning by education authorities seem an obvious way to ensure that teachers are better prepared for such…

Background/Context: Children enter kindergarten with widely varying backgrounds and academic skill levels (Little et al., 2024). Kindergarten teachers face the challenge of meeting children where they are at the start of the year and helping them master critical skills by the end of the year, regardless of where each child starts. Differentiated…

Background: Evaluation methodologies often elevate and prioritize causal evidence especially in large scale studies (What Works Clearinghouse, 2022). Such approaches, including randomized controlled trials (RCTs), can induce rigid learning environments that may limit naturally occurring and dynamic educational activity in order to control for…

The dismal results from the fall 2024 release of "The Nation's Report Card" (the National Assessment of Educational Progress) confirmed what many who follow schooling outcomes for children already feared: post-pandemic academic recovery for students was middling at best, with reading and math scores still falling short of their…

Adaptive number knowledge represents the understanding and use of numerical characteristics and relations. However, there is a lack of knowledge about the role of adaptive number knowledge in solving problems that require the recognition of patterns. Therefore, we studied 61 sixth grade students' adaptive number knowledge and its connections to…

In this article we investigate the extent to which characteristics used to describe mathematical definitions in mathematics education research literature reflect what is important to research mathematicians and mathematics teacher educators. We report results from a comparative judgement survey of 57 research mathematicians and 62 mathematics…

This study used an instrumental approach (Drijvers et al., 2013) to investigate how artificial intelligence (AI) or large language models (LLMs), specifically ChatGPT 3.5, transitioned from an artifact into an instrument for four prospective secondary mathematics teachers through the development of schemes and techniques in using the AI to…

Achievement in mathematics, particularly in advanced mathematics courses (such as trigonometry, precalculus, calculus, or Advanced Placement courses), is important for long-term college and career success. However, many students--particularly students who are Black, Hispanic, or from low-income households--do not have access to advanced…

The purpose of this study was to examine the effects of an online multi-component intervention (video modeling, virtual manipulatives, digital games, self-monitoring and least to most prompting techniques) on the acquisition of several mathematical skills of two autistic elementary school students. We used a multiple probe design of a single-case…

In this portfolio, I reflect on my efforts to provide professional development targeted to support teachers during the launch phase of their mathematics teaching, to elicit and respond to student ideas and experiences. I grounded my study in research on ambitious teaching practices for launching complex mathematical tasks using problem-based…

Purpose: This study was done to compare the modes of teaching mathematics in higher education in the United Arab Emirates (UAE). The three teaching methods were used as follow: before, during and after the COVID-19 pandemic. The three teaching methods are: (1) Normal on-campus face-to-face teaching and learning activity before the COVID-19…

Fostering a culture of professionalism is the work of all stakeholders in a school and can be influenced by participating in self-selected professional development. Professionalism is a trait among teachers that has garnered significant attention within mathematics education. Central to the principle of professionalism is the recognition that…
