The good news is that (I'm told) it's all part of the learning process. Every student feels lost on the first attempt at PBL. Every student spins their wheels and learns inefficiently. But you learn from the mistakes and get better. Next time (I'm told) I'll be more efficient, I won't waste time on needless information and I will remember to look at the relevant theory (a huge oversight in my first attempt). Then I'll make other mistakes and miss other important details, lol.
In the end it's left me feeling pretty disoriented, but I'm hopeful. I AM new at this. If I was expert then I wouldn't need the schoolin'!
All things in time, I keep reminding myself.
All things in time.
