Krashen presented a proposal on language learning with 5 main points. The proposal discusses the Affective Filter Hypothesis which states that factors like motivation, self-confidence and anxiety can act as a filter that impacts whether input reaches the language acquisition device. It also discusses the Suggestopedia technique and adapting Krashen's Monitor Model where acquired competence can become learned competence over time. Additionally, the proposal provides recommendations for encouraging language acquisition in the classroom by focusing on meaning over form through gestures and body language.
