Purdue University has one of the strongest schools of engineering in the United States, and they remain committed to providing new and interesting materials about the art and science of teaching engineering to their students. Professors Phillip C. Wankat and Frank S. Oreovicz recently created this very helpful textbook to aid engineering educators in the classroom, and it is exciting to see that it is available online here for free. Visitors can download the entire book, or they can just browse around through some of the seventeen chapters. These chapters include "Problem Solving and Creativity", "Lectures", and "Learning Theories". Additionally, there are several helpful appendices, such as "Obtaining an Academic Position" and "Sample Teaching Course Outline". Overall, it's an exemplary resource, and one that will be most useful to engineering educators. These materials can be used in a variety of engineering courses, including those that deal with chemical and mechanical engineering.
