Validation of the integral System of Task Analysis for Physical Education

The purpose of this study was to develop and assess the validity of an instrument for analysing the tasks designed by the teacher of physical education. The instrument is organized into nine dimensions: contextual data, teacher data, learning unit data, session data, pedagogical variables, organizational variables, external load variables, communication variables, and task method. 15 expert judges who met the defined inclusion criteria participated in the validation process where assessed the univocity, relevance, and importance of each category quantitatively. Also, they provided qualitative contributions of each item. The content validity was calculated using Aiken's V coefficient and its confidence intervals. The exact critical value of Aiken's V at 99% CI was used for accepting the tasks (V>.78) and at 95% for revising them (V>.70). The mean values of Aiken's V for all items are above the cut-off point obtained at 99% confidence (Univocity: V=.89; Relevance: V=.91; Importance: V=.93). Two categories of the instrument had to be modified [V>.70 -<.78]. The reliability analysis showed excellent Cronbach's alpha coefficient values for Univocity (alpha=.94), Relevance (alpha=.89), and Importance (alpha=.92). The physical education task analysis instrument (SIATEF) showed high content validity and reliability and can be used in tasks analysis for physical education.
