Group work with students you are not familiar working with is never an easy task.
Recently, I was put into a group with the most inconsiderate group member. During our group meetings, he would not allow anyone else to speak; he would not listen to others ideas, and would talk over anyone who tried to raise a point. These are probably the three most frustrating traits to have in a group. As a result, the group presentation came off unprepared, and we lost marks because he did not allow others to speak.
Looking back, I would have used the knowledge about conflict I have learned in class. I would have used the collaborating and compromising techniques. These would have solved the issue without placing the blame on the uncooperative group member, making him feel attacked.
