This paper introduces a framework of two key shifts--epistemological and authority--to conceptualise the challenges mathematics teachers face when moving from classroom teaching to professional development (PD) facilitation. I argue that while teaching and facilitation may appear similar, critical differences in how knowledge is constructed and…

Background: First-year engineering mathematics courses present a critical academic challenge, often leading to a significant decline in student self-efficacy, a key predictor of retention and success. While flipped learning is a proposed solution, a lack of longitudinal research using robust comparison groups has limited our understanding of its…

Usually, it is assumed that the printing revolution initiated in Europe by Gutenberg from 1445 was implemented directly and smoothly for the production of mathematics textbooks. This paper undertakes to investigate this process more closely, showing it to form the precondition for ensuing curricular developments. The characteristics of the first…

Many matchstick puzzles have multiple solutions and are ideal learning tasks for fostering and improving creative thinking. Nevertheless, many puzzle book authors exhibit a strange approach toward these multiple-solution puzzles. For some puzzles, the number of solutions is mentioned after puzzle formulation and these solutions are published in…

This research is motivated by low critical and creative thinking skills. Apart from that, many previous studies have looked at the effect of worksheets on critical and creative thinking skills. It is worth evaluating whether the statistical results of these studies can be trusted and reported. For this reason, this research aims to compile and…

Context/Objective: Although the positive role of a growth mindset, defined as the belief that intelligence can be developed through effort, is widely recognized in math learning (Yeager et al., 2019), meta-analysis studies (e.g., Burnette et al., 2023) have revealed that the impact of mindset interventions varies significantly across classroom…

This paper is focused on the collaborative work of two communities, one of teachers and one of researchers, during a teacher professional development program on the inquiry-based learning approach in mathematics, addressed to lower secondary school in-service mathematics teachers. We conceptualize the design of inquiry mathematics task as the…

This study aims to investigate the thinking process of primary school students when solving mathematical problems. It used a qualitative case study approach. The researcher administered a metacognitive test to 30 fifth-grade students in Yogyakarta and selected three focal participants based on their performance in planning, monitoring, and…

Understanding and accepting that many students feel alienated from the subject of mathematics supports the use of specialized approaches. This article details how one specific mathematical modeling task integrated principles of Universal Design for Learning (UDL) to create an environment where even reluctant students felt like they belonged. The…

Understanding how non-numerical visual features systematically distort numerosity perception holds promise for unveiling the processes that give rise to our visual number sense. Recent studies show that increasing visual coherence systematically increases perceived numerosity, with this effect strengthening over development (DeWind et al., 2020;…

We used a matched samples design to compare outcomes of students enrolled in a traditional model of developmental mathematics education with a similar group of students coenrolled in developmental and college-level math courses. Drawn from students enrolled in a pilot program at nine community colleges in a Southeastern state, we compared 208…

Math anxiety (MA) is a specific feeling of tension generated by the manipulation of numerical stimuli in daily life and academic situations (Richardson & Suinn, 1972). This condition has significant repercussions on the individual's life at personal, social, and economic level. Literature on the topic of MA alleviation, however, is still…

This article describes and evaluates a web-based coaching program designed to support teachers in implementing Common Core-aligned math instruction. Web-based coaching programs can be operated at relatively lower costs, are scalable, and make it more feasible to pair teachers with coaches who have expertise in their content area and grade level.…

Using correct definitions of the mathematical concepts is crucial for learning and teaching of any mathematical content. Being able to make mathematically correct definition of the concepts is an indicator of teachers' content knowledge. The purpose of this study is to determine how preservice middle school mathematics teachers define the concept…

In this study, teacher candidates were asked to evaluate activities designed with the use of the history of mathematics (HoM) as a tool in terms of the obstacles to the use of the HoM. A total of 12 activities which used the HoM as a tool were utilized in the study. The study group consisted of 40 teacher candidates who were first-year students in…
