Cellphone-use in class has many negative effects on students' overall performance. By using a self-developed monitoring-app to record students' cellphone-use in class, this study attempts to explore the relationships of cellphone-use and self-control on academic performance. The subjects of this study are 207 freshmen who take part in advanced…

This study performed a scoping review of the literature concerning the use of technology in mathematics education published between January 1981 and March 2022 to explore research trends. After the defined filtering process, we retrieved 2,433 articles from "Web of Science," "ERIC," and "PsycInfo" databases and…

Research on language in mathematics education is largely dominated by a 'normalcy' of spoken languages. This modal hegemony does not only affect a whole group of learners in failing to provide access that is epistemologically equitable--those using sign language as their preferred mode for mathematical discourse--it also obscures our view on the…

Professional collaboration is widely seen as an important component in educator professional development, but we know little about the interactional processes that undergird teacher learning in collaborative workgroups. This paper focuses on four collaborative workgroups in a yearlong, mathematics-focused professional development series for…

The training of non-specialists, particularly engineers, in mathematics requires designing specific didactic proposals that make the importance of mathematics evident. One approach to creating such proposals consists in analyzing the mathematics used in authentic contexts of engineering research and then effectuating a didactic transposition to…

The presented article is dedicated to a new way of teaching substitution in algebra. In order to effectively master the subject matter, it is necessary for students to perceive the equal sign equivalently, to learn to manipulate expressions as objects, and to perceive and use transformations based on defining their own equivalences. According to…

In this paper, we draw on our recent research to inspect again some of the theoretical perspectives we have been using to analyze data and to characterize teaching-learning in university settings. We focus particularly, within a sociocultural perspective on Activity Theory and the construct the "Teaching Triad," seeking to embed the…

Much important research on the learning of mathematics with technology-supported inquiry has been devoted to learning with multiple-linked representations (MLR) as a mode of feedback. Like a mirror, MLR feedback helps students see their actions in one representation "reflected" in another. Yet, research has followed learning episodes…

In K-12 education, Computational Thinking (CT) has been a trendy issue in mathematics education, but the approach and results of CT + Math are not yet clear enough. This paper systematically reviewed 22 SSCI journal papers from three perspectives: the current status, outcomes, and implications of mathematics and CT integration. Results indicate…

In current teaching materials, when using Dedekind cuts to construct real numbers, the definition of a Dedekind cut is always involved in defining addition and multiplication. In this paper, as it is done in many current textbooks, Dedekind cuts are used to construct the set of real numbers. Then the order in it is defined, and the…

To optimize teacher support, administrators need subject-specific knowledge, skills, and beliefs to lead, not just manage, instructional change. Professional development (PD) is needed with the many roles administrators are already called to fill. In this study, 38 elementary administrators participated in PD in mathematics instructional…

In this article, the authors share two examples of student engagement in visible, mathematical thinking through a Chalk Talk within the four walls of the classroom, as well as the connected spaces of online learning. Five steps for facilitating the Chalk Talk are outlined, with descriptions of teacher moves for each step. The silent thinking…

Bullying generally has been shown to have a number of negative outcomes for student well-being. IEA's TIMSS (Trends in Mathematics and Science Study) 2019 data shows that cyberbullying is correlated with traditional forms of bullying and is particularly relevant in more recent times. The relationship between the two forms of bullying is strong and…

Stereotype threat occurs when educational institutions remind us of the stereotype that men are more successful in mathematics and that women's mathematics achievement is negatively affected. In this study, the effect of stereotype threat on the academic achievement of high school students was examined. In the designed experimental study, there…

Students who study at home certainly affect their self-concept. Their study found that knowledge of distance learning affects the perceived usefulness of this process. This study described self-concept has an influence on learning achievement in mathematics. The type of research used in this study was descriptive quantitative research to determine…
