It's hard to learn practical life skills without applying the knowledge we've learned for that skill. We need to practice skills in order to learn and succeed. The university system may not be set up to accommodate this kind of learning, but I think you see it a little bit in some vocation-oriented classes. For instance, I have to go out and interview people and write stories for my journalism classes. I think this would probably apply for architecture majors who are required to spend hours in the studio and spend time studying under someone.
Apprenticeship is a good example of learning through doing.
You learn from the master, have an opportunity to make mistakes and learn and eventually be let free to work and succeed on your own.
