Esta investigacion tiene como objetivo disenar una herramienta, a partir de dos sistemas de categorias validados previamente, que pudiera analizar las imagenes impresas en los libros de texto de Educacion Fisica (EF) en la etapa de Educacion Primaria. Para ello se desarrollo SAIMEF (Sistema de Analisis de Imagenes en Educacion Fisica), una aplicacion php disenada ad hoc , que facilita el acceso al sistema y minimiza los errores de analisis. La herramienta consta de dos sistemas de categorias para el analisis: SC-I para las imagenes en las que aparece la figura humana realizando actividad fisica (con 72 indicadores) y SC-II para el resto de las imagenes (con 47 indicadores). La validez del sistema se realizo mediante el analisis de tres observadores para comprobar la congruencia de la herramienta. La muestra se compuso de 192 imagenes publicadas en los libros de texto de EF en Educacion Primaria, bajo la Ley Organica de Educacion. Para el calculo de la fiabilidad del sistema se aplico el coeficiente de Kappa que obtuvo una concordancia de 0.81. Los resultados obtenidos indicaron que la herramienta SAIMEF es fiable y valida para analizar las imagenes de los libros de texto de EF en la etapa de Primaria. Abstract. This research aims to design a tool from two previously validated category systems that could analyze images printed on textbooks of Physical Education (PE) in Primary Education. For this, SAIMEF (Image Analysis System in Physical Education) was developed, a php application designed ad hoc, which facilitates access to the system and minimizes analysis errors. The tool consists of two systems of categories for the analysis: SC-I for the images in which the human figure appears performing physical activity (with 72 indicators) and SC-II for the rest of the images (with 47 indicators). The validity of the system was assessed through the analysis of three observers who checked the congruence of the tool. The sample consisted of 192 images published in textbooks of PE in Primary Education under the Education Law. Kappa coefficient was employed to calculate the reliability of the system, obtaining a concordance of 0.81. The results indicated that the SAIMEF tool is reliable and valid to analyze the images of textbooks in primary PE.
