Outline of Final Research Achievements

In this research, we clarified the influence on the estimation accuracy of user ability by the initial condition difference of the elements constituting the e-learning test system based on test theory. As a result, the posterior mean of the ability was stable and good results, and the simple bias correction method of the estimator was proposed for each ability estimate methods. In addition, we proposed a new evaluation model that can utilize more information according to knowledge in the field of reliability engineering. As a result of this research, 5 academic papers and 12 presentations of academic societies were obtained.
