By PETER OMMUNDSEN Problem-based learning (PBL) is an exciting

discussion among students and reinforcing learning. A problem-
based learning environment emulates the workplace and develops
self-directed learners. This is preferable to a mimetic learning
environment in which students only watch, memorize, and repeat
what they have been told. The examples given here are suitable

students must form small work groups during that time. Ask the
students to form groups of 3-5
