The current study investigated the application of the Game Performance Assessment Instrument(GPAI; Griffin,
Mitchell, and Oslin, 1997) in game activities by pre-service elementary school teachers. Data analysis involved
taxonomic analysis(Spradley, 1980) and cause chain analysis(Werner & Schoepfle, 1987) to capture and analyze
students’ reactions during the class activity. The findings of the study could be summarized into three
sections. First, during the 3 weeks of preparation stage of the study, the researcher modified game performance
measure to game involvement only with the exception of support index(SI) because of the complexity of
evaluation criteria. Second, several aspects were perceived as positive during the application stage. The
modification to game involvement resulted an active participation among students and improved their physical,
cognitive, and affective domain skills and abilities. Furthermore, the application of process-oriented assessment
was also perceived to be positive. However, those activities still advantaged high-skilled and physically strong
students and evaluation criteria for game performance was somewhat vague. Finally, the application of the
GPAI would be suitable for activities and games played by offensive and defensive group and with slow pace.
It is also suggested to limit the target subject into small number of people and to make up evaluation criteria
followed by the positions. The future study should investigate the application of GPAI and its evaluation
criteria and method with different types of activities and games.
