Faculty Story

Wiki Usage in a Calculus Course


Lou Rossi
Associate Professor, Department of Mathematical Sciences
University of Delaware


Professor Rossi is now considered a veteran of wiki usage at University of Delaware. He used wikis in his Calculus undergraduate course and his Applied Mathematics graduate course. Using a wiki helps students spend time on solving problems outside of the classroom in a motivating collaborative environment. Publishing in a wiki gets students aware of the fact that they are writing for an audience, which usually results in using common mathematical language and formulas instead of plain English. He describes his class as a tribe, where skillful individuals are leaders and slackers are easily detected. He warns faculty members of the pitfalls of trying to grade students on a wiki.
