PowerPoint: Reflections on a Conventional Teaching Technique

Dr. Southwick’s “Spare me the PowerPoint and bring back the medical textbook” is provocative publication that broaches the important debate of how to most effectively teach medicine. PowerPoint has clearly become the most popular and predominant mode of post-secondary education. There are many potential reasons for this. For one, the PowerPoint is probably the easiest method for mass transmission of pure information: it replaced chalkboards or overhead slides because, without having to recopy text or switch slides, this vastly increases the tempo of information dissemination. PowerPoint also has an impressive host of functionalities for incorporating images, transitions, and movies, which eclipses all its predecessors. And now, more importantly it has become the convention, the expected method of teaching, such that to do anything but would probably raise a few eyebrows.  

 While knowledge is an important aspect of education, operationalizing information is the crux of medical education. For example, not only do we need to know what diabetes is, how it can present, and ideas about management, we also need to actually be able to identify the patient with a new presentation of diabetes, think about what a diagnosis of diabetes means with for a patient in the context of separate issues like hypertension, and develop an individualized management plan. To do all this requires practice and knowledge integration, aspects that we perhaps don’t emphasize enough in pre-clerkship.

 Dr. Southwick’s recommendation of bringing back the textbook is interesting because it is a point that I have talked to others students about and we were nostalgic about the times when learning emphasized textbooks. Textbooks provided a much more satisfying form of learning. Most of us have probably experienced the frustration of not understanding what a point in a slide meant because the point-form structure had taken the idea completely out of context and robbed it of the clarity of linguistic structure. PowerPoint is truly powered for HIGHLIGHTING ideas – points – and not to convey complexity holistically.

This publication also brings up the concepts of Just-in-Time Teaching and Peer Instruction, as useful teaching tools. It also outlined 7 basic principles of teaching that I personally thought would be quite useful to keep in mind:

1.        “encourage contact between students and faculty

2.        develop reciprocity and cooperation between students

3.        use active learning techniques

4.        provide prompt feedback

5.        emphasize time on task

6.        communicate high expectations

7.        respect diverse talents and ways of thinking”


Food for thought: how do we strike the balance between knowing a lot and knowing things well?
