Observations on PBL Projects
Expanding on and reviewing what I had posted on Edutopia FB, I see that a good project would be one that everyone has some success and then the chance to creative. The foam plate glider (FPG-9) worked well for me in those apsects. Projects that are too fragile require too much time from the instructor repairing which I have found with some of my balsa wood model airplane classes.
It is ideal if you have enough tools for everyone or there is minimal sharing. If students try to jump ahead too far in projects they mess things up and they need help re-doing. You can try to explain everything ahead of time, but many will not listen.
Projects with large classes and not enough help could be disasters I would think. The costs for materials for large groups could quickly get out of hand also.
Do not assume anything is too simple, everyone comes into some classes with different backgrounds. I found kids that had so much trouble tying a basic knot. I have heard of engineering students that have never soldered and have trouble trying to build a robot in college.
Just some of my opinios, would like to hear others.
