Content-based instruction is an approach to teaching a second language where students learn the language through learning about real-world content or topics. Students acquire language skills as a byproduct of engaging with meaningful content. This approach contrasts with traditional language teaching that focuses primarily on mastery of the language itself. Content-based instruction can be implemented at various education levels from elementary to university. It provides students opportunities to develop language skills while learning about interesting topics through activities and materials related to those topics.
