The objective of this paper is to establish comparisons between the Linear Algebra (LA) approach practiced in Engineering courses offered by Chilean and Brazilian Higher Education Institutions and, for that, teachers from both countries were interviewed. From a methodological point of view, the research consists of two case studies. For the…

For countries concerned about equity and access to higher education, providing support services for academically underprepared students is critical to increasing their probabilities of success. Corequisite math courses provide opportunities for underprepared students to develop their basic math skills through simultaneous enrollment in…

In this paper, we provide an overall perspective on the teaching and learning of discrete mathematics. Our aim is to highlight what research has been conducted in this area and to connect it to existing research ideas for future work. We begin by characterizing discrete mathematics and its role in the school curriculum, highlighting themes,…

This article examines the effect of two Open Educational Resources (OER)--Khan Academy Collection and a teacher-authored open textbook--on mathematical course performance and attendance amongst first-year higher education Chilean students. It also aims to find out about teachers' and students' views on the use of OER in order to understand how…

Over the past several years, we have been exploring and researching a phenomenon that occurs among undergraduate students that we called extension of linear models to non-linear contexts or overgeneralization of linear models. This phenomenon appears when some students use linear representations in situations that are non-linear. In a first phase,…
