The History of Algebra in Mathematics Education
2006
In this chapter, we analyse key issues in algebra history from which some lessons can be extracted for the future of the teaching and learning of algebra. A comparative analysis of two types of pre-Vietan languages (before 16th century), and of the corresponding methods to solve problems, leads to conjecture the presence of didactic obstacles of an epistemological origin in the transition from arithmetic to algebraic thinking. This illustrates the value of historic and critical analysis for basic research design in mathematics education. Analysing the interrelationship between different evolution stages of the sign system of symbolic algebra and vernacular language supports the inference th…
Modernity and the articulation of the gender system: Order, conflict, and chaos
2009
Gender system can be understood as a cultural system rooted in biological differences. Semiotically speaking, it is a binary sign system (male/female) with some variation involved (transsexuals, homosexuals, etc.). In the process of modernity, the biological motivation of the gender system is being loosened by technological innovations such as contraception and mother's milk substitute. At the same time, the state has replaced family and kin as the organizing structure of society and the cultural ideal of equality has gained a strong position. These and similar changes together have made gender flow in 'post-traditional' societies. The paper deals with this process in paying attention to th…
Researching (Algebraic) Problem Solving from the Perspective of Local Theoretical Models
2010
Concepts such as Local Theoretical Model, Mathematical Sign System, logico-semiotic outline, analytical reading, and formal competence model, elaborated within long term research programs developed in Mexico and Spain, are presented. Empirical data from a study carried out in Spain with students of a teacher training school are analyzed using this theoretical framework. The cases analyzed show to which extent the logico-semiotic outline determines the arithmetic or algebraic nature of the entire problem solving process, even in the case of pupils which had been instructed in general problem solving heuristics, management and control, including the explicit training in changing the plan of s…
From a bodily-based format of knowledge to symbols. The evolution of human language
2013
Although ontogeny cannot recapitulate phylogeny, a two-level model of the acquisition of language will be here proposed and its implication for the evolution of the faculty of language will be discussed. It is here proposed that the identification of the cognitive requirements of language during ontogeny could help us in the task of identifying the phylogenetic achievements that concurred, at some point, to the acquisition of language during phylogeny. In this model speaking will be considered as a complex ability that arises in two different steps. The first step of competence widely relies on a bodily-based format of knowledge. The second step relies on more abstract meta-representations …
Metaphors and metonymies understanding in sign systems
2013
The aim of this paper is to integrate the cognitive linguistic theory and the relevance theory to provide a comprehensive explanation of what metaphors and metonymies are and to explore their interaction. We approach this question through the analysis of metaphors and metonymies in homesign systems developed by deaf individuals who have no contact with the Deaf Community. We conclude that there is a complex interplay between metonymies and metaphors as a result of a process of representing the human experience by exploiting iconicity and contiguity relations between sign and referent. Speaking metaphorically and use metonymies is a complex ability that arises in two different steps. In our …
The dual nature of design management
2018
Design management profession has probably got the least attention in the construction industry. One reason could be the lack of explicit conceptualizations about its nature, subject matter and principles. In this article, a conceptual design management framework is proposed on the premise that design management is the management of a structured system of object and subject-oriented, technical and social design activities. Additionally, an example of a mediating visual model is proposed to facilitate the discussions about design activities and design management in academia and practice. The two major premises of this research are 1) as design management is the management of design activity, …
METAPHOR USE IN SIGN SYSTEM: A TWO-STEP MODEL FOR THE UNDERSTANDING OF METAPHOR AND METONYMY
