Abstract This paper explores OpenCourseWare (OCW) lectures as a key resource for EAP research and practice. The aim is to gain insights into the distinctive features of this technology-driven lecture format and how it may differ from the traditional classroom lecture not intended for an online audience. The analysis was structured into two parts. First, the digital affordances provided by two pioneers of the open education movement (Massachusetts Institute of Technology and Yale University) were surveyed to understand how they support and enhance the lecture experience. Then, 15 lectures from their OCW platforms were analyzed with corpus tools to extract linguistic features of lecturer-audience interaction (i.e., I-you patterns, dialogic episodes, informal expressions). For comparative purposes, the same analysis was performed on a corpus comprised of 15 lectures from the Michigan Corpus of Academic Spoken English. Results showed a wide array of supporting digital affordances beyond video-recorded lectures, including lecture transcripts with metadata, content structuring, and navigational features. The linguistic analysis revealed that the OCW lecturers used considerably more I-you patterns to engage with students on an interpersonal level than the MICASE lecturers. The findings provide insights into how OCW lectures can be effectively leveraged for improving lecture comprehension for EAP settings.

OpenCourseWare 讲座：旧体裁的新转折？

摘要 本文探讨了作为 EAP 研究和实践的关键资源的 OpenCourseWare (OCW) 讲座。目的是深入了解这种技术驱动的讲座形式的独特之处，以及它与不适合在线观众的传统课堂讲座有何不同。分析分为两部分。首先，对开放教育运动的两位先驱（马萨诸塞理工学院和耶鲁大学）提供的数字启示进行了调查，以了解他们如何支持和增强讲座体验。然后，使用语料库工具分析来自他们的 OCW 平台的 15 个讲座，以提取讲师-听众互动的语言特征（即，我-你模式、对话片段、非正式表达）。出于比较的目的，对由密歇根学术英语口语语料库的 15 个讲座组成的语料库进行了相同的分析。结果显示，除了视频录制的讲座之外，还有一系列支持数字可供选择，包括带有元数据、内容结构和导航功能的讲座记录。语言分析表明，与 MICASE 讲师相比，OCW 讲师使用了更多的“我-你”模式来与学生进行人际交往。研究结果为如何有效利用 OCW 讲座提高 EAP 设置的讲座理解提供了见解。和导航功能。语言分析表明，与 MICASE 讲师相比，OCW 讲师使用了更多的“我-你”模式来与学生进行人际交往。研究结果为如何有效利用 OCW 讲座提高 EAP 设置的讲座理解提供了见解。和导航功能。语言分析表明，与 MICASE 讲师相比，OCW 讲师使用了更多的“我-你”模式来与学生进行人际交往。研究结果为如何有效利用 OCW 讲座提高 EAP 设置的讲座理解提供了见解。
