Las ilustraciones en la enseñanza-aprendizaje de las ciencias. Análisis de libros de texto

Abstract

This paper focuses on how important the illustrations in science textbooks can be for understanding their content. To that end we start from a theoretical base of the requirements that those illustrations should accomplish to favour their appropriate processing, as well as from the different morphology that they normally show in textbooks. Then we approach a process of design and validation of a taxonomy to categorize the illustrations that was applied to the subject of Mechanics on a representative sample of seven textbooks of Obligatory Secondary Education (ESO) and three books from a system previous to ESO. After this analysis we discuss the results and draw conclusions aimed at improving the use of illustrations.
