Charles H. Corwin has spent over 30 years teaching chemistry to over 12,000 students. He has taught general chemistry, organic chemistry, and quantitative analysis, but has focused primarily on introductory chemistry for the personal rewards it offers.
Corwin was awarded his degrees from San Jose State University, where he was a member of Tau Delta Phi honor society. Early in his career, he was awarded a National Science Foundation grant to study instructional innovations at Grand Valley State University. Currently, he is a professor of chemistry at American River College, where he was recognized as Teacher of the Year in 1994. He is also the recipient of an Alumni Teaching award from Purdue University.
