Resumen
Resumen: Se presenta una recopilación de las dificultades detectadas por diferentes investigaciones en el aprendizaje de la estequiometría. A partir de estas, se diseña una unidad de enseñanza que busca contribuir con los procesos de enseñanza - aprendizaje e incrementar los niveles de comprensión de los conceptos de la estequiometría en los estudiantes del grado décimo, desde el enfoque de diferentes teorías de aprendizaje, particularmente, la del aprendizaje significativo. Para ello, se propone la construcción de una Unidad de Enseñanza Potencialmente Significativa (UEPS) basada en la secuencia diseñada por Marco Antonio Moreira. Dentro de la unidad se plantea el uso de estrategias como las situaciones – problema, los mapas conceptuales y la V- heurística, orientadas a la indagación de saberes previos, la conceptualización y el desarrollo de competencias
Abstract: The present paper deals with several issues found by a number of investigations regarding stoichiometry; these issues become the basis to design a learning-teaching unit to foster the learning process and help 10th students improve the acquisition and comprehension of such content. Multiple learning and teaching approaches were taken into account making special emphasis on meaningful learning. The main proposal is the design of a Potentially Meaningful Teaching Units (PMTU) based on the sequence developed by Marco Antonio Moreira which involves the use of situation-problem strategies, conceptual maps, and “V” heuristic tools that mainly focus on eliciting previous knowledge and concepts as the foundation to develop competences
