摘要当今的高等教育环境对教师、学生和研究人员提出了挑战，要求他们在学术环境中为国际观众进行有效的口头演讲。本研究探讨了词汇丰富性和组织凝聚力的口头报告由三组主持人：44大学水平的ELF学习者代表新手ELF扬声器，30个会议介绍经济，社会科学，人文和技术从ELFA项目，和23个会议介绍应用语言学从JSCC语料库。三组学生在词汇量的比例和层次、组织手段的数量和变异性上存在显著差异。两个专家组证明，ELF学术演讲不需要大量使用困难的单词或复杂的句子结构;相反，经验丰富的ELF演讲者用85%的基本词汇和15%的学术和专业词汇来构建他们的演讲。与新手严重依赖语法衔接不同，两个专家组在构建小句和信息时表现出词汇和语法衔接手段的平衡使用。量化词汇丰富度和组织凝聚力的程序可以发展成ELF演示文稿的评估规则。未来的研究应该考虑演讲内容、使用准确性和观众评价。
Abstract Today's higher educational contexts challenge teachers, students, and researchers in making effective oral presentations for international audience in academic contexts. This study examines the lexical richness and organizational cohesion in the oral presentations made by three groups of presenters: 44 college-level ELF learners representing novice ELF speakers, 30 conference presentations in economy, social sciences, humanities, and technology from the ELFA project, and 23 conference presentations in applied linguistics from the JSCC corpus. Salient differences were found in the proportion and levels of lexical items, and the quantity and variability of organizational devices between the three groups. The two expert groups demonstrated that ELF academic presentations do not require massive uses of difficult words or complex sentence structures; rather, experienced ELF speakers built up their presentations with 85% of basic and 15% of academic and professional level words. Unlike the novices who relied on grammatical cohesion heavily, the two expert groups show a balanced use of lexical and grammatical cohesive devices in structuring clauses and information. The procedures for quantifying lexical richness and organizational cohesion may be developed into assessment rubrics for ELF presentations. Future studies should take the presentation content, usage accuracy, and the audience evaluation into account.
