Professor Barton is a retired Associate Professor of Education who taught at Dalhousie University in Canada for more than a quarter of a century, helping undergraduate, graduate and doctoral students understand the profounder aspects of teaching. He taught a popular undergraduate course on 'The Methods of Famous Teachers' to 250 students. He made a habit of greeting each student individually as they entered the lecture hall with a summary of the life and work of the famous teacher, and did his best to illustrate that famous teacher's work with slides, videos and so forth.
