The take away from this book can be applied to other things outside of being an educator. The gem of practicing until something becomes automatic is applicable to learning a foreign language faster. Every foreign language course, book, program start you off with vocabulary. If you take that vocabulary and immediately use it day in and day out in your activities you are forcing yourself to become fluent and thus you are making your new language automatic which is faster, than just studying with flash cards or games or grammar books. For example, in each room of your home take 2-3 minutes to name everything in that room. You walk into the kitchen have your vocabulary list for food. You say out loud Apple, juice, milk, oven... You open your closet, and say the translation for pants, shirts, shoes and you do this for the next few days this is automatic in your mind. and you then go to sentences, this is my pants, this is my shirt, this is my apple, this is your coffee. I am happy, my name is John, it is sunny, this is my car, my car is black.
The faster you force yourself into fluency the faster you learn that language because you automate it to the point that you don't think about it. Yes there will be grammatical errors, but those are much easier to fix then learning grammar first and then trying to speak, because it interferes with your creativity and stops your flow, which is another premise in the book. The book says you are most creative when your on automatic. If you are trying to figure out what grammar rule works here and there it will hinder your speaking. That is how someone becomes a polyglot. It takes them a few months to get language fluency because they automate the vocabulary in day to day life, rather then just sitting with the book to study it alone or rely on course time. They eat, sleep and breath that new language until fluency is automatic, and so you immediately stop relying on translating because you already know the new word after a few days.
Try it out, go to an online sentence translator and put in the 3 phrases you use most often. For example: Can I have a coffee please? What time is it? Thank you. And use it for one week, see the difference. Automate your speaking to the most important words and phrases you use and in a month you will start to feel comfortable with your new language.
