The direct method teaches foreign languages exclusively in the target language without using the native language of the students. It focuses on developing oral proficiency through activities like questioning and answering, conversation practice, and self-correction. The teacher acts as a facilitator, introducing new vocabulary visually and inductively teaching grammar. Students are encouraged to think and communicate in the target language from the beginning. While it is effective for pronunciation and oral skills, it requires small class sizes and more teachers due to its immersive approach.
