Rodríguez-Nieto, Camilo Andrés; Rodríguez-Vásquez, Flor Monserrat; Moll, Vicenç Font – Educational Studies in Mathematics, 2023
The literature reports that students have difficulties connecting different meanings, multiple representations of the derivative, and performing reversibility processes between representations of f and f'. The research goal is to analyze the mathematical connections that university students establish when solving tasks that involve the graphs of f…

Aguilar, Mario Sánchez; Castaneda, Apolo – Educational Studies in Mathematics, 2021
We report a study on mathematical literacy with special emphasis on health literacy. In particular, we identify and characterize the mathematical competencies that a citizen needs to interpret the official information on the COVID-19 pandemic as experienced in Mexico. To achieve this, we analyze the daily reports on the pandemic issued by the…

Martínez-Hernández, Cesar; Kieran, Carolyn – North American Chapter of the International Group for the Psychology of Mathematics Education, 2018
This paper presents strategies identified in Mexican rural school students in seeking structure on equivalence tasks that involve the equal sign and tasks that do not. The results arise from the pilot study of a research project on the structure of numbers and numerical operations -- a key aspect of early algebraic thinking. [For the complete…

Solovieva, Y.; Rosas Rivera, Y.; Quintanar, L.; García, M. A. – International Education Studies, 2013
The present study describes the usage of strategies of symbolic representation during teaching introduction of decimal system in primary school in Mexico. Our research is based on Activity Theory conception of teaching-learning process and of gradual introduction of scientific concepts in school age. The method includes symbolic external…

Filloy, Eugenio; Rojano, Teresa; Solares, Armando – International Group for the Psychology of Mathematics Education, 2003
In this paper we analyze the meanings of the "equal" sign as generated by sense production of the methods of substitution and comparison for solving problems and systems of equations of two unknowns. These methods are usually introduced through an extension process of the syntax and meanings recently learned by students in order to solve…

Sutherland, Rosamund; Rojano, Teresa – Journal of Mathematical Behavior, 1993
This longitudinal study investigated the ways in which two groups of eight students used spreadsheets to represent and solve algebra problems and related this to their previous arithmetical experiences and evolving use of symbolic language. The spreadsheet environment supported students to move from specific to general thinking. Includes story…
