Outline of Final Research Achievements

We attempted to grasp the learning behavior and situation based on seld evaluated descriptions, which are written by the learners themselves. In this study we have automated the analysis procedure that was previously performed manually. At that time we introduced a new indication "PCN score", and we predicted the final grade. As a result, we obtained maximum value of 0.71 as accuracy which was culculated by P score.
In order to improve the accuracy, we have tried various method of machine learning, we showed that we can acquire the F1 value of about 95 %. We also use understanging, cooperating, effort to review and prepare as another items for analysis which are inspired from PCN items, and we clarified the features of the new item values corresponding to the final grade.
