Do you love group work or hate it? Formulate your position by synthesizing your own experiences, relating specific course concepts and research findings that support the merit of your view. For example, if you believe "two heads are better than one", you might summarize work on the value of brainstorming. If, however, you think "too many cooks spoil the broth", you might relate the negative impact of groupthink. Any concept in the chapter is appropriate to utilize for this discussion, and you may discuss more than one if applicable.
Explain how you might use this knowledge to influence other members and improve the overall function of a group in which you have been/are currently/will be a member.
