A Study of Second Language Vocabulary Acquisition Based on Corpus Linguistics

With the rapid advancement of globalization, second language vocabulary acquisition has become increasingly significant. The emergence of corpus linguistics has provided a novel approach to studying second language vocabulary acquisition. This paper explores the theoretical foundations of corpus linguistics and second language acquisition while systematically reviewing domestic and international research findings. A comprehensive analysis reveals several issues in current studies, such as inadequate research on lexical pragmatic knowledge acquisition, insufficient discussion on individual differences in data-driven learning (DDL) instruction, and a lack of comparative studies on the effectiveness of different corpus analysis methods. Based on these findings, educational institutions can enhance teaching quality by integrating theoretical frameworks with practical instruction, developing customized school-based corpora, and strengthening teacher training. These efforts will contribute to the advancement of research and development in second language vocabulary acquisition.
