As an IT instructor, I have found that group work helps all my students. In teaching computers, I normally have a very diverse population in regards to student PC knowledge. There are always the ones who already have a strong skill set and others who have never used a PC before. I try to balance my group by my observations of skill sets and assign specific roles for each group member. This allows for the more knowledgeable ones to assist the others and gain experience in sharing their skills while the other gain from learning from their peers.
