My current active interests are in teaching, course assessment, and the developing of instructional materials. I am the author of Organic Chemistry, 4th Edition, published by Oxford University Press, and am a co-author of both Study Guide and Animations compact disks to accompany that text. (The 5th Edition is in preparation, to be published by Roberts and Company.). I have, in collaboration with George Bodner in the Division of Chemical Education, been developing a group-study approach to teaching organic chemistry, which has been implemented in the last several years in my organic chemistry course at Purdue (which has ~250 students).
