This research explored the mental representation of media and digital literacy (MDL) in 242 Mexican high school students through a definitional task based on the natural semantic networks technique. The participants defined ten target concepts related to MDL, using verbs, nouns, and adjectives as definers, and then they rated each definer with a…

This study examines the relationship between the past experiences of secondary education students with their current image of mathematics. It is based on the premise that the image of mathematics is formed through experiences mediated by school, parents, peers, and society. Drawings and interviews were used to explore these experiences. The…

From an APOS (Action-Process-Object-Schema) theory perspective, learning mathematics involves construction of knowledge through mental mechanisms, which evolves between different mental structures or stages. The focus of this study is to explore how transition occurs from an Action to a Process conception, in the context of a task related to the…

This report delineates the outcomes of an intervention conducted with in-service high school educators, focusing on elucidating three distinct scenarios within geometric and arithmetic domains: the infinitely large, infinitely numerous, and infinitesimally close. Grounded in the theoretical framework of conceptual change, it is posited that when…

This article uses cognitive measures previously developed within linguistic relativity research to explore the thinking patterns of Yucatec Maya-Spanish bilingual children in the Yucatan peninsula. These measures were designed to detect cognitive patterns associated with specific language patterns. Here, these measures are used to test whether 12…

The current paper aims to identify the mathematical connections activated by 10 Mexican high school students while solving mathematical tasks that involve the exponential and logarithmic function. We used the Expanded Mathematical Connections Model (EMCM) and the OntoSemiotic Approach of Cognition and Mathematical Instruction (OSA) as theoretical…

Self-rated health (SRH) and subjective life expectancy (SLE) are widely used for understanding health and predicting mortality. However, what these items measure remains unclear, due to the lack of conceptual frameworks. We administered a web survey across the United States, Great Britain, Germany, Spain, and Mexico. The questionnaire included SRH…

San Juan Quiahije Chatino Sign Language (CSL) is a group of six family-based signed language varieties in rural Mexico. This study analyzes the variation of iconic patterns of CSL signs with respect to three semantic categories, tools, food, and animals, using an Embodied Cognitive Phonology framework. Signs are organized around iconic prototypes,…

This paper reports a qualitative case study of college-level English as a foreign language teachers' attitudes towards oral corrective feedback. Our goal is to characterize such attitudes considering a model which integrates cognitive, affective and conative components as well as different aspects of oral corrective feedback. Six English…

In Mexico, approximately 504,000 students pursue a bachelor's degree by means of distance or blended programmes. However, only 42% of these students conclude their degree on time. In the context of blended learning, the focus of this research is to present a causal model, based on a theoretical framework, which describes the relationships…

This article examines a "calculus graphing schema" and the triad stages of schema development from Action-Process-Object-Schema (APOS) theory. Previously, the authors studied the underlying structures necessary for students to process concepts and enrich their knowledge, thus demonstrating various levels of understanding via the calculus…
