In this research, we investigated how interactive digital serious games could be used in traditional, offline, school classrooms. We asked four teachers from four different schools to use a job training serious game in their traditional job training curriculum and the teachers used the game in anyway they intended. As a result, the two main ways to integrate gaming into traditional curriculum were gaming within the curriculum and gaming outside the curriculum, although both methods were used to support the main curriculum. When the game was used outside the curriculum, teachers almost always had the students play the game during the computer lab class. Students also played games voluntarily during recess and at home. The factors that affected how the game was used were teacher, student, and location and accessibility of the computer.
