Students construct knowledge from their own observations and peer discussions
Students are challenged to compare predictions (based on their beliefs) to their own observations
Students change their beliefs when confronted by differences between their initial beliefs and their own observations and experiments
Instructor is a guide rather than an authority

the 1st law is unbelievable
the 2nd law is incomprehensible
the 3rd law is mere religious incantation
