Design, reliability, and validity of a tool for the analysis of images of physical education textbooks

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.
