This article describes a historical case study of E. J. Edmunds, a Black mathematics student and teacher in 19th-century New Orleans. Edmunds's career as a student and then teacher of mathematics, which stretched from the antebellum era through Reconstruction and into segregation, was filled with obstacles and indignities but also with improbable…

This study was carried out to examine the relationship between preschool teachers' mathematical pedagogical content knowledge (MPCK), their attitudes towards mathematics (ATM), and their attitudes towards mathematics teaching (ATMT). The research method was designed according to the relational survey model, one of the quantitative research…

The aim of this study is to determine the effect of the use of concept cartoons on the academic achievements of students in a mathematics course. The model of the research is based on a quasi-experimental design from quantitative research methods and supported by an interview from the qualitative methods. The purpose of qualitative data collected…

Variance and invariance are two powerful mathematical ideas to support geometrical and spatial thinking, yet there is limited research about teachers' knowledge of variance and invariance. In this paper, we examined how high school teachers deal with the task of looking for invariant properties in a dynamic geometry environment (DGE) setting.…

An essential task for mathematics teachers is posing problems. Selecting mathematics problems that develop mathematical proficiency and engage students in desirable mathematical practices is a critical decision-making process. We present the Framework for Posing Elementary Mathematics Problems (F-PosE) developed to focus prospective teacher…

This paper contains information on a study which investigated the use of GeoGebra software in teaching and learning circle geometry enhancing Grade 11 learners' academic achievement in South Africa. The study employed a quantitative methodological research design that included non-equivalent (pre-test and post-test) quasi-experimental research.…

We present the Active Learning tools introduced in basic mathematics courses in the Preparatory Curriculum for Engineering schools at Université Claude Bernard. Additions were introduced in the academic year 2018/2019 in Foundations of Mathematics 2, in the first year of bachelor study program. Its content are Linear Algebra (matrices, vector…

This article analyzes elementary school students' didactical situation in traditional games through ethnomathematics learning. The conventional game studied was "Endog-Endogan" or egg games from the Sundanese culture, West Java, Indonesia. This qualitative and quantitative study applied the design of the didactic learning stage. The…

In this paper a class of regular surfaces, generated by rotation and twist of a rigid line segment, is considered. Firstly a complete description of those surfaces by means of local charts is obtained and then its orientability is characterized in terms of the number of half-twists, taking into account their direction (clockwise or…

This paper describes and examines students' shared construction of meanings while learning about quadratic functions via digital artifacts that simulate real-world phenomena, like the motion of a ball on an inclined plane, focusing specifically on the role of the teacher in that construction process. The study follows the interactions of twenty…

This paper aims to give detailed insights of interactional aspects of students' agency, reasoning, and collaboration, in their attempt to solve a linear function problem together. Four student pairs from a Norwegian upper secondary school suggested and explained ideas, tested it out, and evaluated their solution methods. The student-student…

A part of students learning in the classroom depends on how the teacher responds to their thinking. The literature has separately addressed teachers' feedback responses to errors and unexpected strategies that students put into play when solving tasks. We propose a framework to analyze these responses together based on three criteria: the focus of…

Systemic thinking skills are an increasingly important aspect of contemporary life for all students. Therefore, the first aim of the present study was to investigate the relationship between systemic thinking skills, epistemological beliefs, and mathematical beliefs in a sample of 120 secondary school students aged 16-18 years in Saudi Arabia. The…

During the Fall 2021 semester, the author taught a university-level geometry course into which they incorporated texts and discussions on mathematics and mathematical epistemology from outside of the "Western" tradition typically centered in college math curricula. Analysis of student survey responses and students' reflections on their…

Background: Despite the interest and potential of multi touch devices, there are limited published studies researching their effectiveness and usability specifically with children with Down syndrome, one of the most common groups of children with an intellectual disability. This is particularly true for mathematical learning, an area in which many…
