The aim of this article is to carry out a work of networking theories which combines two perspectives on the mathematical activity involved in a modelling process, in order to answer the following question: To what extent does the application of the onto-semiotic tools complement the analysis from a cognitive perspective of a mathematical…

What comes to mind when one thinks about building? One may envision constructions with blocks or engineering activities. Yet, constructing and building a number system requires the same sort of imagination, creativity, and perseverance as building a block city or engaging in engineering design. We know that children invent their own notation for…

Various features have been found hidden in the Pascal triangle. In this paper, some very well-known properties of the Pascal triangle will be presented, as well as the properties related to different extensions of the triangle, namely the Pascal pyramid. Given that in the textbooks of the tenth grade, respectively in the school, where we realised…

The interactions young children have with adults are of vital importance in developing mathematical reasoning. This paper describes the behaviours of teachers who work with young children in school yet manage to have individual and natural mathematical conversations with children. These mathematical interactions young children have with their…

This article focuses on first-year university students' understanding of concepts related to third-degree polynomial and trigonometric functions that they encountered during their study of Grade 12 mathematics. In this study three online questions from two first-year mathematics quizzes at the University of KwaZulu-Natal were analysed. The first…

Humans have the remarkable ability to solve different tasks by simply reading textual instructions that define the tasks and looking at a few examples. Natural Language Processing (NLP) models built with the conventional machine learning paradigm, however, often struggle to generalize across tasks (e.g., a question-answering system cannot solve…

Middle school students (n = 144) worked with an applet specially designed to introduce the concept of function without using algebraic representations. The purpose of the study was to examine whether the applet would help students understand function as a relationship between a set of inputs and a set of outputs and to begin to develop a…

Learning transfer has been studied for over a century, though studies are primarily through the lens of the researcher or an expert. The purpose of this project was to better understand the student perspective in transfer by examining how they approached transfer tasks and how these approaches related to classroom instruction. The Actor-Oriented…

For young people, financial literacy is important because they face financial decisions that can have significant consequences throughout their lives, such as investing in a college education or a business, shopping, buying books or computer games. Therefore, this study examined the relationship between the financial literacy levels of young…

According to commognitive conceptualization, development of mathematical thinking, whether historical or ontogenetic, requires periodic transitions to mathematical discourse "incommensurable" with the one that has been practiced so far. In this new discourse, some familiar mathematical words will be used in a new way. Historically, such…

Mathematical literacy, quantitative literacy, numeracy, matheracy, disciplinary literacy, and content-area literacy are among a plethora of terms used to link mathematics and literacy. In addition to this abundance of terms, the content of the terms is not precise, and in some cases the terms are used interchangeably. I delve into this landscape…

This study used a qualitative, holistic case study to explore obstacles tutors faced when implementing high cognitive demand (HCD) tasks and the possibility of using embedded educative curricular supports to overcome them. Much prior research has explored using educative supports in classrooms with teachers (Davis et al., 2017), but more research…

Scholars propose that contextual problems can be used to ground students' understanding of mathematical ideas, and recent curricular trends have resulted in a plethora of resources that introduce and develop new mathematical ideas through contextual problems (CPs). Given the tension between this approach and the traditional role of CPs as…

In Lebanon, science is taught in an international language (French or English) based on a language-in-education policy rooted in Lebanon's colonial history. Given the intersection among social/socioeconomic class, educational equity, and science performance, learning science in a language other than one's own raises concerns around…

Providing opportunities for elementary students to engage with enduring social issues, such as houselessness, is essential in preparing informed, engaged, and social justice-oriented citizens. This article draws from the following standards: (1) C3 Framework for Social Studies Standards that center inquiry; (2) Learning for Justice's Social…
