中文摘要:

      以大数据、人工智能等为代表的数字技术正在重塑教育形态，驱动学校场域深刻变革，影响并重构学校传统的教学方式和育人模式。为探究教育数字化资源对高中生话题词汇习得的影响，该研究聚焦单元主题语境的理解，采用实验班对照班前后测设计，随机选取同质性某高中二年级的两个平行班为对象，对实验班采用英语视听说数字化教学。结果发现，实验班在形符与类符、分级覆盖率、高频类符与高频主词、核心词汇覆盖率、N-Gram 多元词组和个案分析六个方面得分显著优于对照班，这表明教育数字化资源能够提升高中学生的话题语汇习得水平，彰显了教育数字化资源对于英语视听说教学的独特价值，为研究者开展教育数字化转型研究提供了可供借鉴的范例。

英文摘要:

      Digital technologies such as big data and artificial intelligence are reshaping the form of education， driving pro? found changes in school fields， and reconstructing traditional teaching and educational modes. To explore the impact of educa? tional digital resources on high school students’ topic vocabulary acquisition， this study focuses on understanding the context of the themes of units and adopts a pre-test and post-test design for an experimental and a control class selected from the parallel classes in Grade Two of a high school. The experimental class adopts digital English teaching in English audio-visual-speaking. The results indicate that the experimental class significantly outperforms the control class in terms of morphological symbols and generic symbols， hierarchical coverage rate， high-frequency generic symbols and headwords， core vocabulary coverage rate， NGram multi-word units， and case analysis. Such findings demonstrate that educational digital resources can enhance high school students’ topic vocabulary acquisition level， can highlight the unique value of educational digital resources in English audiovisual-speaking teaching， and can provide a reference for the researchers who want to carry out the study on educational digital transformation.
