This is one of the things that I studied in my graduate program. It is highly important for students to feel as if they are gaining skills. Competency translates into confidence, and spurs many students on to success. I have noticed in my classes that when students are working on projects in groups and independent assignments, they have stopped relying on me to give answers, and are more willing to search out the answers for themselves. I have moved from being the "sage on stage" to actually facilitating. I'm sure that 3d game lab is going to even further my student's (and my own) progress.
