The direct method of teaching foreign languages refrains from using the learner's native language and uses only the target language. It focuses on developing oral skills through techniques like questioning and demonstration without translation. In contrast, the grammar-translation method uses the learner's native language and focuses on learning grammatical rules and translating sentences between the target and native languages to develop reading skills. It pays less attention to speaking and listening. While the direct method aims to build direct associations between language and experience, the grammar-translation method's goals are to enable reading literature and develop general mental discipline through translation.
