Communication and collaboration work together to deepen knowledge. I liked the use of rubrics and peer evaluation. I am left with a question (from my own personal experience) as to how are students prepared to deal with a member of their team who refuses to show up, or not follow through on their contribution to the project? Peer evaluation may be one way to allow students to express their disappointment, and yet how is that communicated respectfully and positively? Also, if the project is graded, do all suffer for the lack of contribution by one?
