Intelligent Educational Systems for Augmentation of Teacher's Abilities of in Communication

将智能辅导系统看作是教师和多个学习者之间的中介，我们已经解决了如何从教师那里获取辅导知识的问题。一般来说，家教要将自己的知识外化并不是那么容易的事。为了便于知识外化，我们相应地提供了描述辅导知识的基本词汇表。在这种方法中，这些词汇被要求恰当地表示学习过程，并有助于描述知识。首先，我们在理解计算机词汇、编程和物理等领域建立和完善了学习模型。然后，我们从模型中提取了基本词汇。其次，我们提供了用提取的词汇描述辅导知识的大纲，将辅导目的限制为促进和加强学习两个目的。第三，我们考察了基本词汇是否允许我们描述课本中的问题和解释。因此，他们中的大多数都可以被描述出来。我们还确定了课本中没有的辅导信息，这些信息可以用词汇来描述，在促进和加强学习方面是有效的。基本词汇使教师能够增强他/她与学习者交流的能力。我们已经在与人工智能和教育工程相关的国际会议上以及在国内和国际期刊上发表了研究成果。

Regarding intelligent tutoring systems as mediators between a tutor and a number of learners, we have addressed an issue of how to elicit knowledge of tutoring from the tutor. In general, it is not so easy for a tutor to externalize his/her knownledge by himself/herself. In order to facilitate the knowledge externalization, we have accordingly provided fundamental vocabularies which are primitives to describe tutoring knowledge. In this approach, these vocabularies are required to appropriately represent learning process and to be helpful in describing knowledge. First, we have built up and refined learning models in the domains such as understanding computer vocabulary, programming, and physics. We have then extracted fundamental vocabularies from the models. Second, we have provided an outline of describing tutoring knowledge with the extracted vocabularies, restricting tutoring purposes to two which are to facilitate and to reinforce learning. Third, we have examined whether the fundamental vocabularies allow us to describe problems and explanations in text books. As a result, most of them could be described. We have also ascertained that tutoring information not included in the text books, which can be described with the vocabularies, is effective in facilitating and reinforcing learning. The fundamental vocabularies enable a tutor to amplify his/her capability of communicating with learners. We have already published the research results in international conferences related to artificial intelligent and educational engineering, and in national and international journals.
