An interactive open-source calculus textbook is compared to a popular commercial textbook. Structured as a non-inferiority study, use of the open-source textbook does not harm student outcomes, and there is evidence that the open-source textbook is better than the commercial textbook in promoting post-course enjoyment of mathematics and confidence…

Engaging students in processes of mathematizing and active knowledge organization (instead of telling and rehearsing ready-made mathematics) is a key demand for high quality mathematics instruction. Although many mathematically rich context problems have been designed and published in textbooks, their impact on regular mathematics classrooms…

Using lesson observations, the study reported in this article explores how two practising secondary mathematics teachers implemented formative assessment actions in their classroom teaching. The study also investigated whether teachers' beliefs about teaching and assessment could be mapped onto their classroom practices. In particular, while the…

The purpose of this research was to perform a meta-analysis to draw conclusions about the effectiveness of traditional, cooperative, constructivist, and computer-assisted teaching, and also to compare the effectiveness of these four approaches over the last twenty years. So, the present research adopted meta-analysis technique. In order to…

In this article, the authors introduce the Into Math Graph tool, which helps teachers learn about their students' mathematics-related experiences and mathematical engagement by inviting students to define and graph their engagement over time. This tool documents and allows teachers to understand how and why students' engagement increases,…

The purpose of this mixed-methods study was to investigate the relationship between teachers' conceptions of mathematics and their use of intelligent tutoring systems for mathematics instruction. Intelligent tutoring systems are adaptive computer programs which administer mathematics instruction to students based on their cognitive state. A…

Teaching gerrymandering in our high school geometry classrooms provides students with a unique opportunity to use mathematics to describe, analyze and make sense of the world around them. Our purpose is to provide our students the opportunity to apply learned definitions and formulas of area and perimeter to a sociopolitical context. We present a…

Interest in providing one-to-one technology to students is increasing, particularly in low-income schools. This study examined the impact of one such approach on kindergartners' math and literacy development during an academic year in a small urban public school district. A district-wide outreach program provided tablets to every kindergarten…

Design activities help students develop their three-dimensional thinking skills and gain engineering and technology literacy. This study investigated whether the spatial abilities and 3D geometrical thinking skills of the students differed according to approaches to learning mathematics before and after engineering design-based mathematics (EDBM)…

Structure sense can be interpreted as an intuitive ability towards symbolic expressions, including skills to perceive, to interpret, and to manipulate symbols in different roles. This ability shows student algebraic proficiency in dealing with various symbolic expressions and is considered important to be mastered by secondary school students for…

Changes and developments that take place in technology also cause changes in education and learning. In defining the sufficiency, appropriacy and sustainability of new student services, knowing about the student satisfaction levels carry an imporant role. For this purpose, this study aimed to find about the student satisfaction level regarding the…

Despite the importance of artificial intelligence in our daily lives, it has yet to be integrated into K-12 classrooms in a meaningful way. This article explores a lesson in which geometry students use Euclidean distance to implement a functional machine learning algorithm in Google Sheets™. The assignment requires students to apply the distance…

The Pandemic has required teachers to find ways to provide high-quality instruction in a virtual format. Video-based instruction (VBI) is a version of technology-aided instruction that has been effectively used in classrooms to improve mathematical outcomes for students with disabilities. This manuscript describes how a special education teacher…

In this paper, we consider the perceived effectiveness of using industry-based transdisciplinary, complex problems as a vehicle for final year undergraduate mathematics students to apply their knowledge and skills in realistic settings, preparing them for the world of work. The discussion centres on a recently designed, implemented and evaluated…

This study focused on the assessment of the structural validity of the 28 item adapted Teacher Assessment for Learning Questionnaire (TAFL-Q) in the Kenyan context. The sample consisted of 180 mathematics teachers drawn from 50 secondary schools. Confirmatory factor analysis was used to confirm the hypothesised two-factor model of the original…
