Resumen

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.
