All the members of the Faculty Advisory Committee for the College of Education at the University of Iowa have resigned in a growing disagreement between professors and administrators over the college's direction, the Associated Press  reported. The chair of the committee said he was ordered by Provost P. Barry Butler to turn over and destroy comments made in a survey about the performance of Margaret Crocco, the education dean. The comments apparently were quite negative. Faculty leaders say that they aren't being listened to by the dean, and aren't sure how to move forward with administrators seeming uninterested in their grievances. Butler said that the comments haven't been destroyed and will be considered. Crocco said that she was working to improve communication with the college's faculty members.
