I disagree. You do attain knowledge from work. Knowledge and learnings comes in different forms and levels.. There’s the knowledge that you gain from books and lectures in a class. And there’s, what we call, hands-on knowledge, which is MORE meaningful to people because you’re physically interacting with.
I’ve often heard professionals say that their courses provided them with knowledge about the jargon of their field…but it didn’t teach them how to deal with various situations related to their work. In other words, your classes didn’t teach you how to handle a particular situation. And many people gain “knowledge” about that through trial and error at work.
I’m an education major…my courses taught me methods of teaching…they didn’t teach me about. But there was so much practical classroom management related stuff I had to figure out through trial and error once I started working. Life exists outside of uni…you gain knowledge about so many things everyday (TV…reading…interacting with others…through your own successes and failures).
