Research and Development of an agent-based collaborative learning environment focusing on social networks

近年来，教育系统的研究者试图为教育理论所倡导的合作学习提供技术支持。特别是，网络的爆炸性增长增加了广泛开展协作和开放式学习活动的可能性。本研究探讨开放式合作学习活动的技术支援，开发出可可CoCoA -（Communicative Correction Assistant system），以支援外籍教师与教师透过电子邮件交换标记文件。它的环境与人们使用纸和笔的真实的环境非常相似。可可不仅允许教师修改外国人通过电子邮件发来的作文，而且外国人可以看到教师在哪里以及为什么修改了他们。可可化的CoCoA提高了外国人的日语作文和接受教师指导的机会。接下来，我们提出了一个名为Neckle（Network-based Communicative Kanji Learning Environment）的外语辅助系统。Neckle有一个软件代理到互联网通信环境中，考虑到学习者的母亲和目标语言之间的差异。Agent观察学习者与本族语者之间的对话，根据CGM发现交际差距，并注意到这些差距，从而支持适合每个学习者的语言学习。学习者也可以从本族语者那里获得不同的知识，从而扩大了知识库。

Recently, researchers in educational systems attempt to provide technological support for cooperative and collaborative learning advocated by educational theories. The explosive growth of networking, in particular, raises the possibility of widespread collaborative and open-ended learning activities. We have investigated on technological support for open-ended and collaborative learning activities.In this research, CoCoA -(Communicative Correction Assistant system) has been developed for supporting foreigners and teachers to exchange marked-up documents by e-mail. Its environment is very similar to a real one in which people use paper and pen. CoCoA allows teachers not only to correct the compositions sent from foreigners by E-mail, but also foreigners to see where and why the teacher had corrected them. CoCoA improves the opportunities that foreigners have for writing Japanese compositions and for receiving instructions from teachers.Next, we proposed a foreign language supporting system called Neckle (Network-based communicative kanji learning Environment). Neckle has a software agent into Internet communication environment, considering the difference between learner's mother and target languages. The agent observing the conversation between learner and native speaker, and detects communicative gap according to CGM, and notice the gap, then, supporting language learning congenial to each learner. Learners also get different knowledge from native speaker and the knowledge database is enlarged.
