What is the underlying theory of the Natural Approach to second-language instruction?

The underlying theory of the Natural Approach emphasizes that language acquisition is driven by meaningful interaction in a context-rich environment. This approach is grounded in the belief that language is best learned when learners engage in authentic communication, allowing them to use the language in real-life situations rather than through isolated drills or rote memorization. The Natural Approach aligns with the idea that learners develop their language skills naturally, absorbing vocabulary and grammar in context, rather than through formal instruction focused solely on rules.

In this methodology, the focus is on comprehension and the importance of emotional and social factors in language learning. Learners are encouraged to engage with the language in ways that are relevant and interesting to them, facilitating a more intuitive grasp of the language as they progressively acquire fluency and communicative competence.
