Automatización de retroacciones en DGpad y su impacto en la comprensión de los criterios de congruencia de triángulos

Abstract

In this work, the incorporation of automation of return acts was explored using the DGpad software. To do this, four tasks were designed and programmed focused on the development of understanding of the properties of triangles and the congruence criteria. These tasks were implemented in an experimentation phase with three eighth grade students, who interacted with DGpad using various software tools. During the experimentation, the students' actions and the use of feedback were analyzed, evaluating how these influenced the change or reinforcement of their strategies. The results obtained in this phase provided valuable elements on the impact of the automation of return acts on the understanding of geometric properties, producing adaptive learning.
