That’s not really what I’m referring to (or at least, only a little). Once you have a mental model of something, you can for sure think on it or build on it without interaction, but to initially set up our mental models (as children or whatever), I believe it takes interaction. Once we have a base, we can think abstractly about it and learn, but building that base.. Or, put another way, its my belief that you can “_improve_ your physical skills” by thinking, but to buildthe skill in the first place, interaction is necessary. But even if its not true and interaction isn’t strictly necessary, I think (wrongly oerhaps) that few people would disagree that usually learning by doing is far superior that only learning by thinking/reading/listening/watching. So even if not neccesary, its at least more efficient (doing both together is probably most efficient).
