A more manageable resource than Grasha's entire book. This 8-page paper that appeared in "College Teaching" essentially outlines chapter 4 of his larger work "Teaching with Style". It includes the 5 teacher styles, 4 teacher style clusters, types of teaching methods associated with each cluster, as well as factors to consider when choosing a teaching method. It also contains more of the details and background in Grasha's research on teaching styles.
Great summary charts of Grasha's learning styles, teaching styles, and teaching clusters, as well as a detailed chart of teaching methods and suggested approaches as it applies to the medical profession.
This is a pdf of a whole book, but Chapter 4 (p154) is particularly pertinent to my presentation on teaching styles. It goes over the 5 teacher styles, 4 teacher style clusters, types of teaching methods associated with each cluster, as well as factors to consider when choosing a teaching method. It also contains more of the details and backgrounds in Grasha's research on teaching styles.
