lb our knowledge, the only study published using the ICGM was that by Tallir et al. (2007) •
They examined the efectiveness of two approaches (ICGM and traditional) with primary
school children with respect to basketball game performance (decision making and motor skill
efficiency and efficacy) • All three components improved in both groups, but learning profiles
were diferent, with the IGCM group showing a major increase in game performance from
pre・test to post-test, while the traditional group caught up at the retention test. In a study com-
bining a Sport Education hybrid model with ICGM during a soccer unit, Mesquita, Farias, and
Hastie (2012) demonstrated improvements in students* decision making and skill execution
during game play, particularly in girls and lower-skilled students. The authors suggest that the
team members' strong commitment and motivation to practice, which accompanies team mem-
bership, prolonged engagement with the basic game form.
