Students have very strong opinions about when to talk and when to remain silent. Sometimes, students speak out of nervousness. Other times, students speak because they have something they have to say to the world. Then there are other students who are shy and never want to talk, or who remain silent because they are afraid to look foolish.
Cooperation is not a foreign concept for students. They are told at all stages of life that it is important to cooperate with others. It is also the case that they are expected to be self-reliant and not afraid to accept the hard work that comes with doing things alone.
