The purpose of this study is to considerate on construction of teaching materials in the field of games, especially in elementary physical education. In this paper, the main problem is to present the idea of “explicit exaggeration” and to explain its meaning and method in invasion games through analyzing cases on construction of teaching material as task-game.
Construction of teaching materials means to modify full-game that played by adults with all the inherent techniques and tactics. “Representation” and “Exaggeration” are viewpoints of game modification in the theory of TGFU (Teaching Games for Understanding). “Representation” is the method of making games that maintains most of the tactical complexity of full games but reduces the problems posed by the technical and physical limitations of children. “ Exaggeration” is game modification that intend to exaggerate the tactical problem in games. Two examples of instruction used modified invasion game as teaching material (basketball and soccer) were investigated with game analyses. In these cases of modification, setting specific area that is important for shooting, devising form of goal and compound using of both ways were explained as concrete methods for modification.
These methods of explicit exagger ation involve pedagogical functions as follows.
a) facilitating intentional play for making use of space.
b) amplifying selective play based on decision-ma king. These functions of modification are related to common appreciation of game and cooperative play between teammates.
Accordi ngly, the idea of “explicit exaggeration” is able to be indicated as “the strategy that additional rules are adopted as game modification in order to facilitate intentional and selective play based on decision-making (tactical awareness) in games”.
