Recursos heurísticos para la actividad de enseñanza de las transformaciones geométricas en el nivel preuniversitario.

ARMANDO MORALES CARBALLO EDGARDO LOCIA ESPINOZA (2016)

This article describes a teaching strategy to promote education planning isometric transformation: translation, in the pre-university level. The methodological theoretical framework that underpins the work fall on the contributions on methodologies for problem solving procedures (Locia, E., Mederos, O. Morales, A. Rodriguez, J. M, and Sigarreta, J. M. (2014) heuristic devices (Torres, P. 2013) and use GeoGebra as a fundamental heuristic device.

The teaching-learning process of education in Mexico establishes that students¿ knowledge should be developed. It motivates us to look for alternatives that respond to the requirements stated in the educational reform and contribute to improve mathematical processes at the middle and higher levels of education. In this paper, we show the progress of the research, which aims to elaborate and put into practice a didactic engineering for the treatment of a specific content of middle high school mathematics: the analysis of functions through a system of activities according to the stages described in the methodology.

The Theoretical didactic approach to the counterexample in mathematics.

ARMANDO MORALES CARBALLO EDGARDO LOCIA ESPINOZA MELVIS RAMIREZ BARRAGAN (2018)

This article describes a theoretical-didactic approach to the counterexample within mathematics and its process of teaching-learning, emphasizing the importance of inducing a logical thinking by introducing counterexamples as a process of maturation of mathematical thinking. In addition, it is argued that the counterexamples are not very used in the teaching of mathematics, unlike the important role they have in the professional mathematic activity.

El contraejemplo en la elaboración de la definición de función convexa por estudiantes universitarios

Armando Morales Carballo José María Sigarreta Almira Edgardo Locia Espinoza Juan Carlos Hernández Gómez (2019)

En este artículo se reportan los resultados de una investigación que tuvo como objetivo identificar el papel que juega el contraejemplo en la elaboración de definiciones matemáticas. En particular se analizó el caso de la función convexa en un grupo de estudiantes de nivel universitario. Los elementos teóricos y metodológicos primarios que sustentaron el trabajo descansan en los aportes sobre pruebas y refutaciones, elementos de heurística, lenguaje y axiomática y en el debate científico en cursos de matemáticas. Como resultado fundamental se destaca que el debate científico favoreció mediante la discusión en torno al concepto de función convexa y a la formulación de contraejemplos. Estos contribuyeron en la comprobación de casos particulares, la formulación y refutación de conjeturas, hasta aproximarse a la presentación clásica de la definición. Establecemos también que el contraejemplo es un recurso didáctico y una herramienta mediadora que contribuye en los procesos de elaboración y comprensión de la definición matemática.

In this paper the results of an investigation that aimed to identify the role played by the counterexample in the elaboration of mathematical definitions are reported. In particular, the case of the convex function; in a group of university students was analyzed. The principal theoretical and methodological elements that supported the work rest on the contributions in proof and refutations, elements of heuristics, language and axiomatics and in the scientific debate in mathematics courses. As a fundamental result, we emphasized that the scientific debate favored, through the discussion on the concept of convex function and the formulation of counterexamples These contributed to the verification of particular cases, the formulation and refutation of conjectures, until approaching the classic presentation of the definition. We also establish that the counterexample is a didactic resource and a mediation tool that contributes in the processes of elaboratio and understanding of the mathematical definition.

Teaching-learning about optimization problems: a close up through the use of GeoGebra software.

ARMANDO MORALES CARBALLO JOSE EFREN MARMOLEJO VEGA EDGARDO LOCIA ESPINOZA ANGIE DAMIAN MOJICA (2019)

A teaching-learning proposal is described for the treatment of optimization problems in the pre-university student. The theoretical-methodological elements fall into the heuristic principles and resources and the use of GeoGebra software, on this basis is conceived the identification, selection and formalization of the way of solution, control and assessment as fundamental stages.
