Study on an e-learning system for technical Chinese courses

为确保中国与日本科技交流的顺利进行，支持日本企业在中国开展业务，我们一直在进行这项研究，为日本工程师开发技术汉语课程的电子学习系统。首先，我们收集和构建了基础技术汉语的内容。然后，在教学设计的基础上，运用ADDIE(分析、设计、开发、实施、评价)模型开发了一个基于网络的技术汉语课程及相应的网络学习系统。为提高学习效率，运用多媒体学习认知理论中的七项原则，构建了基于网络的技术汉语课程。特别是，我们对冗余原则进行了修改，以适应语言教学。最后，为了找到一种既能帮助学习者记忆又能让他们练习新词汇的方法，我们制定了静态图像、视频片段或动画的使用标准，并讨论了一个项目的发音应该播放的最佳次数。在听力实验结果的基础上，我们设计了一种新的词汇呈现方法。

To ensure the smoothness of scientific and technological exchanges between China and Japan, and to support Japanese companies doing business in China, we have been carrying out this study to develop an e-learning system for technical Chinese course for Japanese engineers. First, we collected and built contents of basic technical Chinese. Then, based on instructional design, we employed an ADDIE (analyze, design, develop, implement, evaluate) model to develop a Web-based technical Chinese course and the corresponding e-learning system. To improve learning efficiency, seven principles of the cognitive theory of multimedia learning were used to build the Web-based technical Chinese course. In particular, we modified the redundancy principle to suit language teaching. Finally, to find a way that not only helps learners remember but also enables them to practice new vocabulary items, we made a standard for the use of static images and video clips or animations, and discussed about an optimal number of times the pronunciation of an item should be played. Based on listening experimental results, we devised a new presentation method for vocabulary items.
