Abstract
espanolEn este trabajo realizamos un estudio detallado de los problemas de proporcionalidad compuesta de doce libros de texto espanoles de segundo curso de Educacion Secundaria Obligatoria (13-14 anos). En concreto, se realiza un analisis de contenido textual y a priori, clasificando los problemas atendiendo a su contexto, su estructura, su posicion y papel dentro de la Unidad Didactica correspondiente y a la tipologia de magnitudes utilizadas. Entre otros resultados se concluye que, aunque la presencia de problemas varia ligeramente en cuanto a numero entre los distintos textos, el tratamiento es bastante homogeneo respecto a su contexto, estructura y magnitudes implicadas: la mayoria de los problemas son de contexto realista, de valor perdido y con cinco cantidades de magnitud extensivas. Tambien se detecta poca presencia de problemas de comparacion cuantitativa y de situaciones de tipo inversa - inversa, asi como poca presencia y variedad de magnitudes intensivas. EnglishIn this work, we make a detailed study of compound proportionality problems from twelve 8th grade (age 13-14) Spanish textbooks. In particular, we perform an a priori, textual content analysis, classifying the problems according to their context, their structure and their position and role in the lesson where they appear. We also focus on the typology of the magnitudes used by the authors. Among other results, we conclude that, even if the number of problems varies slightly between different books, the treatment given to them is quite homogeneous regarding the context, structure and use of magnitudes: most of them are realistic missing value problems in which five quantities of extensive magnitudes appear.
