Abstract

Class-evaluation questionnaires completed by students are one method used for faculty improvement at universities in Japan. However, it is difficult to improve lectures using the results of questionnaires that contain only a few items. Therefore, in this study we develop a system to support lesson improvements based on short questionnaires. To achieve this, we use a hierarchical item bank that can estimate the answers to questions that are not asked, providing more information to help teachers improve. In the system, we assume that the questionnaire items have probabilistic causal relationships. The system uses sensitivity analysis and soft evidence to determine the specific items that can produce a high level of improvement. Then, we use the relationships between these items to increase the level of teaching improvement.
基于分层题库的教学改进支持系统开发
由学生完成的班级评价问卷是日本大学提高教师素质的一种方法。然而,利用问卷调查的结果来改进讲座是很困难的,因为问卷调查只包含几个项目。因此,在本研究中,我们开发了一个系统来支持基于简短问卷的课程改进。为了实现这一目标,我们使用了一个分层题库,它可以估计没有被问到的问题的答案,提供更多的信息来帮助教师改进。在系统中,我们假设问卷条目具有概率因果关系。该系统使用敏感性分析和软证据来确定可以产生高水平改进的具体项目。然后,我们利用这些项目之间的关系来提高教学改进的水平。
