Educational linguistics is a research area that focuses on the application of linguistic theories and methods to issues related to language education. It seeks to understand how language is learned and used in educational contexts, and how this knowledge can inform language teaching practices. Educational linguistics covers a wide range of topics, including second language acquisition, bilingual education, literacy development, language policy, and language assessment. Researchers in this field often work to develop more effective language teaching methods and policies that are based on scientific evidence and principles of language learning.
