A Study on advanced learning software in multimedia environment

本报告提出了一种方法来构建一个语言和沟通学习系统，避免无聊，激发自发学习。该方法首先构建一个包含多个故事的情景网络，然后根据学习者在对话情景中对多项选择题的选择，系统根据网络情景为学习者提供有意义的故事。当学习者意识到先前的选择随着故事的发展而导致矛盾时，他或她可以通过回溯并做出不同的选择来修改故事。这种语言学习方法被称为“情境和语境依赖”，因为如果学习者看到任何矛盾，故事可以修改。讨论了将故事线重构为场景网络的方法以及该系统的功能。通过实验验证了该方法的有效性。讨论要求参与者通过有效的陈述来说服他人。我们开发了一个计算机系统，以协助几个学习者之间的合作，在创建一个给定的主题报告。另一方面，利用本研究所建立的JSL电子词典，构建了日本手语学习支持系统。该系统通过动画和视频图像的方式，使学习者能够学习手语的发音。我们打算在将来评估这个系统。

This report proposes a way to construct a language and communication learning system which avoids boredom and provokes spontaneous learning. This method first constructs a network of scenarios with multiple stories built into it. According to learner's selections to multiple-choice questions in dialog situations, the system then provides the learner meaningful stories by following the network scenario. The learner can modify the story by going back and making different selections, when he or she realizes that the previous choices have lead to a contradiction as the story develops. This method for language learning is called 'Situation- and Context- Dependent, 'in that the story can be modified if the learner sees any contradictions. The method to reconstruct a story line into a network of scenario and the capabilities of such a system are discussed. Effectiveness of the method was verified by an experiment.Discussion is one of the communication method. Discussion requires participants to persuade other by making presentations effectively. We developed a computer system to assist collaboration among several learners in creating reports for a given topic. Effectiveness of the system was verified by an experiment.On the other side, we construct JSL (Japanese Sign Language) learning support system with JSL Electronic Dictionary which we build in our research. The system displays animation and video images so that Learners can study articulator of sign. We intend to evaluate this system in future.
