An onto-semiotic analysis of the mathematical connections established by one in-service mathematics teachers and university students when solving a problem about launching a projectile using the derivative was carried out. Theoretically, this research was based on the articulation between the Extended Theory of Mathematical Connections and the…

The learning of algebra represents a difficulty within the mathematics learning process. Precisely because of their epistemological and ontological nature, semiotics provides a good key to understanding the main difficulties that hinder the learning of algebraic objects. The answers to a large scale assessments task that requires a treatment in…

In this work we will analyze the relation between registers of representation and the construction of the fraction concept. Ninety-six students from first year of compulsory secondary education participated in the study, and performed equal share tasks in the context of Egyptian fractions (unit fractions with different denominators). The aim was…

Mathematical tools allow us to clearly explain the phenomenon studied in administrative science. Various studies have shown that linear function is a concept, widely used in administration, as well as in other kinds of science, but difficult for students to grasp and assimilate as a tool in their studies. That is the reason that the objective of…

Arrows are recognized as efficient visual elements in conveying location, direction, connection, and process because the shape is thought to have an immediate, common sense impact on viewers. However, the results of our prior quantitative study did not support the assumed effects of arrows in reading energy pyramid diagrams. The current study…

The use of different registers to represent mathematical concepts enhances understanding. For example, rational numbers can assume pictorial, symbolic and natural language representations and this kind of change improves learning. Based on these assumptions, a teaching experiment for the learning of rational numbers by 2nd grade students was…

In this article we examine the nature of inter-semiotic and intermodal construction in the exposition of a solution for a geometry rider. In the tradition of hermeneutic phenomenology, this case study involved an exploration of the oral discourse and visual texts used in a mathematics lesson. This research was intended to contribute to the…

Tackling mathematics tasks often involves reading and interpreting different semiotic resources such as natural language (words), mathematical notation, and images. This study aims to enhance knowledge of how meaning relations, in the form of "cohesive ties" between and within different semiotic resources, are related to how difficult it…

The relevancy of linear algebra (LA) in different areas and also the difficulties faced by undergraduate engineering students studying this content are well known. Grounded on this premise, we aimed at articulating papers related to the teaching and learning of LA in engineering undergraduate programs through a mapping of the main investigations…

As college students enter engineering, they face challenges when they navigate across various transitions. These challenges impact whether a student can successfully adapt to the rigorous curricular requirements of an engineering degree and to the norms and expectations that are particular to engineering. This article focuses on the transitions…

Recently, attention in modern linguistic theory has been shifted to facilitating a broader understanding of the world, in which language is a tool to establish a bridge between the interlocutor and the recipient. To do so, the development of linguistic, communicative and sociopragmatic competences enriched with socio-cultural inputs in English as…

We examined multimodality (the representation of information in multiple semiotic modes) in the context of international test comparisons. Using Program of International Student Assessment (PISA)-2009 data, we examined the correlation of the difficulty of science items and the complexity of their illustrations. We observed statistically…

Drawing on semi-structured interview data, this paper examines one man's multimodal engagement with the emotionally difficult aspects of his Chilean heritage. It builds on recent work (e.g., Marshall & Toohey, 2010) that has begun to unearth the intersection between funds of knowledge (González, Moll, & Amanti, 2005), difficult knowledge…

Slowmation is a twenty-first century digital literacy educational tool. This teaching and learning tool has been incorporated as an assessment strategy in the curriculum area of science and mathematics with pre-service teachers (PSTs). This paper explores two themes: developing twenty-first century digital literacy skills and modelling best…

Graphic novels in the K-12 classroom are most often used to motivate marginalized readers because of the lower text load and assumption of easy reading. This assumption has thus far been unexplored by reading research. This qualitative multiple-case study utilized think-aloud protocols in a new attention-mapping activity to better understand how…
