Experience is huge in the theory and practice of Automatic Language Growth, which claims that even as adults we can effortlessly pick up new languages and approach native-like levels of fluency and ability.
The ALG approach is based on the notion of comprehensible input popularized by Dr. Stephen Krashen, who said the only way we acquire language is “when we understand messages.”
In developing ALG, Dr. J. Marvin Brown narrowed this idea of understanding messages down to “happenings”: hearing the target language in meaningful situations that have elements like a ‘who’, a ‘what’, a ‘when’, a ‘where’, a ‘why’, and a ‘how’.
The idea is to create understandable experiences through which students can pick up language without paying attention to the language.
ALG argues that rather than age, the adult tendency to focus on and analyze language is a main reason why older learners don’t learn them as successfully as young children, who cannot consciously do that.
But in implementing ALG, Dr. Brown wanted a lot more than plain old “happenings”.
