The correct answer is The Natural Approach (Krashen), The Direct Method (Berlitz). The Natural Approach, proposed by Krashen, emphasizes the importance of comprehensible input and believes that error correction is not necessary for language acquisition. The Direct Method, developed by Berlitz, also focuses on immersion and communication, prioritizing speaking and listening skills over error correction. Both approaches suggest that error correction should be kept to a minimum in foreign language classes to allow for natural language acquisition.
