Implementación del aprendizaje basado en problemas para enseñar la conversión de unidades de longitud en séptimo grado en Esmeraldas

Abstract

This research focuses on the implementation of Problem-Based Learning (PBL) to teach the conversion of length units in the Metric System to seventh-grade students in General Basic Education in Ecuador. The study combines a quasi-experimental design with control and experimental groups, evaluating academic performance and the development of mathematical skills using validated instruments. The results show a significant gain in the experimental group, demonstrating that PBL promotes active learning, collaboration, and a better understanding of the content. In addition, recycled concrete materials are used to adapt to unfavorable socioeconomic contexts, emphasizing the importance of innovative and adaptable methodological strategies. Finally, it is recommended to continue with broader and more in-depth studies, integrating mixed approaches to enrich the evidence. Keywords: Problem-Based Learning, Decimal Metric System, Unit Conversion, Knowledge Construction, Mathematics Education.
