"BUT how can teams be selected fairly?" "BUT the students don't know how to deal with intra-team conflict." "BUT what ifa team member does not participate?" "BUT what if one student does all the work? "BUT how can grades be assigned fairly? "BUT should a team be graded individually or should a team grade be assigned?" "BUT how will I find time for the extra work that will be required?" "BUT I don't know anything about teamwork." "BUT the poorer students will drag the good students down." "BUT the good students will prevent failures of those students who deserve to fail."
