Development of Game-Wise CAI and the Prerequisites

Abstract

When answering multiple-choice questions, students frequently use “elimination” instead of “positive selection” by looking for the right answer as a means of arriving at the correct choice. Since discrimination between these two methods is important to proper academic evaluation, the author proposes a CAI system permitting such discrimination to be conducted based upon game theory. In other words, an element of “gaming” is included within the framework of the question-answer process. The author reviews the results of this system in light of both game statistical decision theory, and discusses the prerequisites to construct this framework. In the framework, if a student answers correctly, whether he/she gains points is dependent upon whether the answering was done by “elimination” or “positive selection.”
