There probably isn't one. Universities love to claim they teach critical thinking but this is a claim they can get away with only because most people don't have critical thinking skills: obvious followup questions may include "how" and "what's your definition of critical thinking". One problem is that your three requests are somewhat at odds. Collaboration works against creativity and critical thinking in my experience because of pressure to conform to the group, or find ideas acceptable to the group. Being truly creative requires exploring ideas that might not pan out, or which are a bit off the beaten path. Group work also increases the cost of the work which can change the cost/benefit analysis. When I look at my own life, arguing with people on the internet has been far better for my own critical thinking skills than the humanities lectures I attended at university were. The latter were entirely useless.
