In the world of second language education, there is a mainstream approach that you could call “factory-based” learning. Essentially, you are told all the answers (all the “parts”) – the grammar, the vocabulary definitions, etc., and it’s up to you to put them together, to assemble intelligible language through speech and writing. You require an authority who has designed the system to do your work.
Whereas Language Hunting offers you another approach – “experiment-based” learning. You make observations, you hypothesize, you experiment, and then you have your “aha!” moment when you get results. You never finish experimenting – you hold all your “answers” lightly – but in this way you become self-sufficient at this process of absorbing fluency in new areas.
In the end, it comes down to this. Do you want dependent learners, who need you to progress? Or do you want self-sufficient learners, who can also teach you a thing or two?
