Impacto de la plataforma ALEKS en los procesos de conversión entre registros semióticos de la función cuadrática en estudiantes de primero de bachillerato de la Unidad Educativa Hontanar

Abstract

Abstract: This research evaluated the impact of the adaptive platform ALEKS on the processes of conversion between semiotic representation registers of quadratic functions among 12 students in their first year of *Bachillerato* (upper secondary education) at the Unidad Educativa Hontanar. To address the issue of relying solely on an algebraic register, the study employed a quantitative approach with a single-group, pre-experimental design, incorporating both a pretest and a posttest. Quadratic functions were explored through technological mediation and the system s adaptive scaffolding. Data collection instruments included the platform s automated initial diagnostic and a semiotic conversion test administered at the end of the intervention. The results revealed that, initially, students possessed limited knowledge regarding semiotic representations; following the intervention, there was a 64.6% increase in learning. The effectiveness of switching between different representations improved from 2.1% to 66.7%. The primary contribution of this article is the validation of the ALEKS platform as a tool that facilitates an effective mediation environment grounded in the Theory of Knowledge Spaces for multi-representational coordination.
