Since the first game of American football in 1869, where the University of Rutgers played against Princeton (Brinke & Kränzle, 2012, p. 74), a lot of things in the game have changed through the course of its history. Since those early beginnings it has spread across all over the planet (e.g. in Austria it exists since 1976) (Plenk, 1993, p. 14). Through the years different leagues were founded and dissolved again. Likewise the rules have undergone a frequent change as well. Due to this development, different variations of the original game surfaced, where one of them is flag football. Like the original game, Flag football evolved through the course of the 20th century in North America (Lapp, 1998, cited from Ullrich, 2012, p. 278). At the end of the 1990s flag football also launched in Central Europe. Since 1997 the sport has gotten more and more popular in schools (Ullrich, 2012, p. 278). Behind that reasoning a flag football school-course was developed in the context this work. The course was specifically developed for the 10th school grade and it consists of eight units, where each unit lasts 100 minutes. The base module covers the fundamentals of football (e.g. throwing and catching). In the advanced modules, more elaborate elements of the game like offensive and defensive tactics are taught. Due to the fact that the focus of each unit is the game of flag football itself, the presented concepts are always explained in the context of their applicability in the game. Furthermore during each unit it is ensured that there is always enough time to actually play the game. The course concludes with a flag football tournament.The course is aimed at providing an attractive alternative to common ball games like soccer or basketball. Moreover the course should stimulate interest in team sports among pupils in general, particularly for those with no preexisting interest in that area.
