Abstract

Based on the interdisciplinary characteristics of second language acquisition research, this article systematically sorts out the research methods of second language acquisition from the perspectives of linguistics, psycholinguistics, social culture, and cognition, and examines the language accuracy, complexity, and fluency of learners. Measurement methods and corpus analysis methods are used as supplementary research perspectives, expounding the different understandings of the research perspectives on second language acquisition research and different corpus collection and analysis methods. The article concludes with a summary of the application status of second language acquisition research methods in my country, and points out that there is no right or wrong research method itself. Chinese second language acquisition researchers should flexibly choose and combine research methods from different perspectives and make them local To promote the scientific development of second language acquisition research by conducting multi-party verification.
