The document summarizes the Natural Approach, a philosophy of language teaching developed by Tracy Terrel and Stephen Krashen in the 1970s-1980s. It focuses on developing communicative competence through comprehensible input, using activities that enhance acquisition. The teacher emphasizes listening initially and allows for natural stages of speech production, without forcing early speech. The affective filter is important to help lower students' anxiety levels. The approach was later associated with more traditional methods but focused on principles of natural language acquisition.
