Enseñanza de las expresiones algebraicas en educación secundaria a partir del lenguaje cotidiano y de la tecnología digital Scratch

Abstract

RESUMEN: El álgebra ha sido señalada como un área que involucra diferentes habilidades del pensamiento matemático y su enseñanza en muchas ocasiones se ha dado de forma descontextualizada, lo cual hace que sea considerada de mayor dificultad en el sistema escolar y, por ende, limita a los estudiantes en la asociación de expresiones del lenguaje cotidiano y del lenguaje algebraico. Por esta razón, el presente trabajo de investigación analiza el diseño e implementación de una estrategia de enseñanza que favorezca la asociación del lenguaje cotidiano y las expresiones algebraicas en estudiantes de grado octavo, por medio de la integración de tecnología, al emplear recursos digitales como Scratch. Este trabajo se fundamenta en una investigación cualitativa como práctica interpretativa, a partir de un estudio de caso y de la recolección de datos desde múltiples fuentes de información como observaciones, producción manuscrita (física y digital) de los estudiantes y entrevistas. Estas fuentes se analizan por medio de la categorización, codificación, triangulación de la información y análisis de documentos. Los resultados del estudio permiten concluir que las múltiples representaciones que posibilita el uso del recurso digital Scratch y las retroalimentaciones dadas entre estudiante-estudiante y estudiante-docente favorecen la asociación del lenguaje cotidiano y el lenguaje algebraico.

ABSTRACT: Algebra has been identified as an area that involves different mathematical thinking skills, and many times it has been taught in a decontextualized way. For that reason, it is considered harder in the school system, and subsequently, as limiting students in the association between expressions of everyday language and those of algebraic language. Therefore, this research analyzes the design and implementation of a teaching strategy that favors the association between everyday language and algebraic expressions in eighth-grade students by integrating technology when Scratch as a digital resource is used. This study is grounded in a qualitative research as interpretive practice based on a case study and data collection from multiple sources of information such as observation, students handwritten production (physical and digital), and interviews. These sources are analyzed by using the categorization, coding, triangulation of information and document analysis. Study results allowed to conclude that the association between everyday language and algebraic language is promoted due to multiple representations provided by the digital resource Scratch and the feedback given between student-student and student-teacher.
