Abstract
We aim to support teachers to grasp major contents of many descriptive answers quickly. For this purpose, we developed the three-step-view system. The system provides answers by three steps: keyword, phrase, the full text. In this article, we discussed the effectiveness of the three-step-view system, which supports teachers to grasp major contents of many descriptive answers. We conducted experiments to find frequent phrases from many descriptive answers. By using the three-step-view system, subjects extract longer and more phrases than by the table-view system. And the result of eye tracking and questionnaire shows the effectiveness of functions of the three-step-view system.
