Helping people learn critical thinking also requires active learning strategies. Charles Bonwell through the auspices of the KSU IDEA Center offers workshops and has a web site with bibliographies, strategies and useful links: http://www.active-learning-site.com

Australia's Tim van Gelder has a much better site than mine for linking to all sorts of useful information and tutorials about critical thinking. Click here
