Abstract
El presente trabajo es parte de una investigación más amplia, de tipo cualitativo, en la que se aplicó la investigación-acción crítica y que pretendió, fundamentalmente, desarrollar una primera aproximación a los proyectos educativos relacionados con el problema de la valoración de las distintas fuentes de energía, que permitieran adquirir conocimientos matemáticos a los y las estudiantes de tercer año de educación media¹. Entre las conclusiones del estudio podemos destacar: 1) a partir del problema de la valoración de las distintas fuentes de energía, se logró desarrollar el concepto de función; y 2) los y las estudiantes utilizan representaciones, procedimientos y conceptos matemáticos para interpretar la situación planteada, pero además se apoyan en el fenómeno analizado para comprender las ideas matemáticas.
The present article is just a part of a wider qualitative investigation, which have used the critic action-research method and have pretended, most of all, to develop a first approach to the educational projects related to the different energy sources valuation problem, designed to allow the students of the third grade of Medium Education² the acquisition of mathematical knowledge. These are some remarkable conclusions of this investigation: 1) beginning from the different energy sources valuation problem, we got to develop the "function" concept; and 2) the students use mathematical concepts, procedures and representations, in order to understand the established situation, but also they use the analyzed issue in order to understand mathematical concepts.
