| description | This article is the result of a type of action research with a qualitative approach that was developed with eighth grade students of Basic Education (13-15 years old). The purpose was to improve the variational thinking skills in the students chosen as a focus group. A diagnostic test was applied to evaluate the students' performance in the variational and geometric thinking. Based on the results, the group was intervened with a didactic unit, designed under a constructivist approach, using specific material and virtual manipulators. During the process it was observed that the implemented strategies motivated the students to achieve the objectives proposed by this study, even though initially the students did not feel sure of what they were doing because of the lack of experience in the use of specific instructional materials; however, there was evidence of improvements in the development of variational thinking, which suggests that in the topics of the current course and the following, students will have a better performance. |

El presente artículo es el resultado de una investigación de enfoque cualitativo, del tipo investigación acción, que se desarrolló con estudiantes de grado octavo de la Educación Básica (13-15 años). El propósito fue propiciar mejoras del pensamiento variacional de los estudiantes seleccionados como grupo focal. Se aplicó una prueba diagnóstica para evaluar el desempeño de los estudiantes en los pensamientos variacional y geométrico, este último dado el enfoque de la propuesta. Luego se intervino al grupo con una unidad didáctica diseñada bajo un enfoque constructivista, utilizando material concreto y manipuladores virtuales. Durante el proceso, se observó que las estrategias implementadas motivaron a los estudiantes para avanzar en los objetivos de este estudio, a pesar que en principio los estudiantes no se sentían seguros de lo que hacían por la falta de experiencia en el uso de material concreto. Asimismo, se evidenciaron mejoras en el desarrollo del pensamiento variacional, lo que sugiere que en temáticas propias del curso y de los posteriores, los estudiantes tendrán mejor desempeño.
