| dc.description.abstract | This study focuses on the knowledge revealed and developed by Elementary Mathematics teachers, in a teacher education course related to the representation of fraction division and the flexibility of the reference unit. The teachers solved a task aimed at mobilizing (and accessing) their knowledge related to their approaches to the sense of division, representation, and reference unit regardingfraction division. The results suggest that teachers face challenges when representing and justifying fraction divisions using pictorial models, especially when the divisor is a non-unit fraction. This is based in a gap regarding the flexibility of the reference unit to which the numbers refer in their representations, as well as a challenge concerning the sense of fraction division and the different forms of representation. With this research we intend to contribute to reducing the scarcity of empirical studies in the area and the importance of this specialized teachers’ knowledge to deal with this topic | es_ES |
| dc.description.abstract | Este estudio se centra en los conocimientos revelados y desarrollados por profesores de Matemáticas de Primaria, en un curso de formación de profesores relacionados con la representación de la división de fracciones y la flexibilidad de la unidad de referencia. Los docentes resolvieron una tarea destinada a movilizar (y acceder) a sus conocimientos relacionados con sus enfoques del sentido de la división, representación y unidad de referencia respecto a la división de fracciones. Los resultados sugieren que los maestros enfrentan desafíos al representar y justificar divisiones de fracciones usando modelos pictóricos, especialmente cuando el divisor es una fracción no unitaria. Esto se fundamenta en un vacío en cuanto a la flexibilidad de la unidad de referencia a la que se refieren los números en sus representaciones, así como un desafío en cuanto al sentido de la división de fracciones y las diferentes formas de representación. Con esta investigación, pretendemos contribuir a reducir la escasez de estudios empíricos en el área y la importancia del conocimiento de los docentes especializados para tratar este tema | es_ES |
