The purpose of this study is to come up with the proper method of corporal punishment, based upon game theory. Analyzing the instructional and discipline situation using the game theory, how to reach the equilibrium of the game was explored and under what circumstances corporal punishment can be minimized was examined. The research method was basically literature review, survey, and rational analysis of incomplete information, imperfect information, and perfect information game theory.
The major conclusions are as follows:
First, the rationality of students and teachers pursuing maximum utility needs to be assumed. Second, in the game of imperfect information, the actions able to cause corporal punishment were done by students and corporal punishment was not done by teachers. Third, in the game situation of incomplete information, when the probability of corporal punishment is over 50%, bad actions were done by students. Forth, in game situation of complete information, the actions able to cause corporal punishment were not done by students, corporal punishment didn't have to be done by teachers. In a word, holding the possiblity of corporal punishment rather than prohibiting corporal punishment could inhibit the bad behaviors.
