Zusammenfassung

Handball is a sport in which many actions occur with speed and the pressure of time and space. It constitutes a special context in the decisions making of the players. The aim of this study was to analyze the performance and decision making using the Game Performance Assessment Instrument (GPAI), in situations of numerical equality (three against three) and numerical inequality (three against two) during 396 cycles of game performed by12 students of High School. Significant differences were obtained between the situations of numerical equality and inequality in three of the seven indices: in Decision Making (p=0,047), Technical Execution (p=0,032) and in Mark (p=0,050). In the first two indices the differences were in favor of numerical inequality situations and in the third, the differences were favorable in the situations of numerical equality. Finally, it could be concluded that GPAI is a valid instrument of assessing for an educational context offering an alternative to the evaluation model orientated exclusively towards the skills. Key words: GPAI, Physical Education, numerical Equality-Inequality.
