Exploring Corpus-Based Teaching Methods for High School English Vocabulary—Taking Unit 2 Natural Disasters from Yilin Edition Compulsory Book 3 as an Example

作为数字化语言研究的核心引擎，语料库为高中英语词汇教学提供海量真实语境数据。在主题语境框架下，教师可整合语料库与教材资源，构建多模态教学模型，聚焦目标词的搭配与类联结，设计任务型认知训练。该方法不仅能提升学习者语用规范度，更通过构建语义场促进主题词汇内化，实现从机械记忆到语境化应用的认知跃迁，有效突破传统词汇教学在语义深度与语用能力培养上的瓶颈。As the core engine of digital linguistic research, corpora provide massive authentic contextual data for high school English vocabulary instruction. Within thematic contextual frameworks, educators can integrate corpus resources with textbooks to construct multimodal pedagogical models, focusing on collocations and colligations of target words while designing task-based cognitive training. This methodology not only enhances learners’ pragmatic accuracy but also promotes thematic vocabulary internalization through the construction of semantic fields, thereby achieving a cognitive transition from rote memorization to contextualized application. It effectively addresses the limitations of traditional vocabulary teaching in developing semantic depth and pragmatic competence.
