| Research Abstract |
We aim to realize a training system using the questions of SPI2 (Synthetic Personality Inventory 2) which is widely adopted as an employment examination for arts students who do not like study mathematics. In order to give an adaptive question, our system needs to estimate each student's ability and item difficulty in the test item database. We tried to apply Item Response Theory (IRT) to solve this problem. However, it is very difficult to actually set up all the item difficulties in the test item database for two reasons, that is, the high updating frequency of test items in the database and a restriction of assumption of local independence. In order to solve this problem, we proposed the method of estimating the item difficulty using the hierarchical relationship between questions and the number of formulas in the calculation process. We developed the system based on this method and published on our website.
