Content-based instruction teaches a second language through academic content rather than through grammar lessons. It uses topics from other subject areas to provide meaningful context for language learning. The goals are to motivate students by letting them use the target language for real-world purposes, and to reflect students' academic needs. Language is taught through texts and discourse on various topics, with integrated reading, writing, listening and speaking skills. The curriculum follows the topics from subjects the students need for their studies. Objectives include developing language skills, learning strategies, and academic skills while also broadening understanding of other cultures. Teachers must be experts in the academic content and help students work collaboratively to make sense of authentic materials.
