Kevin Hartman is a bvery good teacher; He is easy to follow, not simple though, which shows the professional level of the course. His course uses online script - presentation-, so as a foreign student with English as a second language, I could easily follow his lecture, by relating content both from his voice and presentation.
The course presents current market, trends and thoughts of professionals, which is the reason I took it, since I work in the Greek market - which is influenced a lot from the US trends. References, articles, posts, were great, and easy to read, without being long.
I have being participating in other courses in Coursera, and I will miss Mr. Hartman's lecture-style.
