I find active learning activities vital in teaching applied science subject matters. When using small groups, I try to pair some of the aggressive learners with less aggressive learners. My hope is that the stronger personality will help the other, however, this may not be the best approach. Sometimes I notice some students will sit back, not because they have less desire to learn or participate, but they allow others to dominate. Do you have any suggestions to overcome this situation? I have attempted to pair the less dominate personalities together as well, but it is a great feeling when the students seem to pull one another out of their shell. I want to provide a comfortable environment for these students, but I fear they may not get the best experience based on the pairing.
