It's the top-down approach (not the official name of the method, I don't know what it's called, but this is what it is) where you read or listen to a lot of the language, with maybe the help of some comman vocabulary. It's how kids are taught languages, and it's how people learned languages when crossing borders. They'd learn what some common objects are called (like we teach kids what a chair is, etc) and then they listen to the language being spoken, and this helps them understand the rules.
The other method is the classroom method, or what Duolingo uses. The bottom up method. There they teach grammar before language. I never found this method to work for me.
Also, grammar has many exceptions. In fact, bad grammar also often conveys the same meaning as right grammar, and based on context, one can judge what the meaning was supposed to be. Learning a language by making them learn (vague) rules isn't how humans should be taught.
