Good teaching is about passion
When I was a law student in the 1970s, we had one lecturer whose teaching was simply appalling. He sat while lecturing (with no physical reasons for doing so). He never looked at the class. He never asked questions, rhetorical or otherwise. He never encouraged analysis. His delivery was monotonous. He never showed or used humour. He never varied the content of his lectures from year to year. In examining, he rewarded (and therefore got) the uncritical regurgitation of his own views. He was a kind of icon of pedagogical awfulness.
What made this particular lecturer so terrible was that he seemed to have no passion of any kind for his subject, or for the topics that he covered. His teaching, if it was that, was simply something that got him from the beginning to the end of the lecture, and from the beginning to the end of the academic year. It had no purpose other than that of filling an allotted slot in the syllabus. This kind of emotional disengagement is however contagious. A lecturer who shows no real interest or spirit stirs up similar apathy amongst their students. Despite that, some of them will base their careers on the topic in question, and will become another generation of the disengaged.
All subjects, if they are worth teaching, are worth getting excited about. When I was a PhD student in Cambridge, I occasionally amused myself by attending the lectures of a Botany lecturer who had this extraordinarily infectious enthusiasm for his subject. I knew nothing about the subject, but I loved the passion he showered on it.
There are many things that make a lecturer good. Charles L. Brewer, Professor of Psychology in Furman University, in a well known address in 2005 on the Joy of Teaching, stated that he had always ‘tried to teach with passion, preparation, parsimony, perseverance, and patience.’ I would suggest that the greatest of these is passion.education, higher education
