It is within our grasp to solve the problems facing our nation and world. To get there, we must reject the lure of polarization and dogmatic certainty and instead, seek interdependence and collaboration. The world depends on it. –Clif Conrad is a professor of Higher Education at the University of Wisconsin-Madison and co-author (with Todd Lundberg) of the book “Learning with Others.” Todd Lundberg is an associate director in the Center for Teaching, Learning & Mentoring at the University of Wisconsin-Madison.
