项目摘要

The purpose of the present study was to develop an authoring system which made it easier and less expensive to create web-based Computer-Assisted Language Learning courseware using video materials.For a methodological framework to teach English, we adopted the "Three-Step Auditory Comprehension Approach," as we successfully developed a series of CD-ROMs in our previous studies using this methodology. Subsequently, we determined the specifications of the authoring system, which enabled the learner to access the materials through a web browser using a CD-ROM or the Internet, depending on the user's environment. The authoring system also had a feature for the ease of CALL materials development. The text, including directions, questions, hints, answers and explanations, was written on Excel files in line with the methodology. Then the Excel files were converted into XML files, simply by dragging the files onto the converter we developed. The XML files were linked to audio, video and image files stored in particular folders and all the multimedia components were automatically integrated into the CALL system using the preinstalled JavaScript. The conversion process can be done in a few seconds, without the knowledge of XML or JavaScript.To demonstrate the efficacy of the authoring system, we developed a set of CALL materials using the system. Conversations between international students and a professor at a university in Japan were videotaped and transcribed. Then the multimedia files and the text we edited were successfully integrated into a CALL system. Twenty-six students used the materials on the Internet in addition to the CD-ROMs we developed in our previous studies. The questionnaire survey revealed that the users were as satisfied with the new materials as with the older materials which required significantly more funding. We concluded that the new authoring system considerably improved the environment for materials development.

本研究的目的是开发一个基于网络的计算机辅助语言学习课件的制作系统，使其更容易和更便宜地使用视频材料。作为一个教学方法框架，我们采用了“三步听觉理解法”，因为我们在以前的研究中成功地使用这种方法开发了一系列光盘。随后，我们确定了编写系统的规格，使学习者能够根据用户的环境，使用CD-ROM或互联网通过Web浏览器访问材料。该创作系统还有一个便于CALL材料开发的特性。教材，包括说明、问题、提示、答案和解释，都是按照方法用Excel文件编写的。然后，Excel文件被转换成XML文件，只需将文件拖到我们开发的转换器上。XML文件被链接到存储在特定文件夹中的音频、视频和图像文件，所有多媒体组件都使用预安装的JavaScript自动集成到CALL系统中。转换过程可以在几秒钟内完成，无需XML或JavaScript的知识。为了证明写作系统的有效性，我们开发了一套CALL材料使用该系统。国际学生和日本一所大学的教授之间的对话被录像和转录。并成功地将多媒体文件和我们编辑的文本集成到一个CALL系统中。26名学生使用了互联网上的材料，除了我们在以前的研究中开发的CD-ROM。问卷调查显示，用户对新材料和旧材料一样满意，后者需要更多的资金。我们的结论是，新的创作系统大大改善了材料开发的环境。
