I have always found the teaching demo portion of a faculty job candidate’s visit to be the least useful component of assessing that individual’s fit for the position. Think about it—for teaching-focused institutions, teaching demos are held in high regard and are often a mandatory component of candidate job-talk visits. The prevalent belief appears to be that without seeing an individual in action in front of a live classroom, one cannot assess their teaching ability.

To me, it seems rather like expecting an interviewing physician to come into an ongoing surgery and take over the operation for half an hour before retreating and handing the patient back to the original surgeon. This seems hardly fair to the visiting physician or the beleaguered patient.

A teaching demo often involves the job candidate having to go teach a portion of a lecture in an already existing and functioning course. Right off the bat, the entire premise of the teaching demo is unnatural and flawed. Neither the demo giver nor the demo receivers benefit, and the observers (i.e., the hapless search committee members), who are the ones most invested in the demo, gain nothing of value, either. Yes, maybe you can determine in 20 minutes how a candidate speaks in front of an audience, but that factoid can be gathered from a research or job talk presentation as well. In that job talk presentation, perhaps the candidate can also talk about his or her teaching philosophy. That to me seems more valuable and more useful information to gather.

One big issue for me about the teaching demo is that the students in attendance know it’s a demonstration and are probably not too fussed about paying too much attention, knowing that whatever the demonstration covers, the contents are unlikely to make it into the exams or quizzes given by their regular instructor. So it would not be surprising if they base their evaluations entirely on random criteria, such as one’s sense of sartorial style.

Essentially, the demo serves as a distraction for students—a way to let their minds wander from their regular programming. I would argue that this sort of demoing is disruptive for student learning and regular instructor teaching. We are taking away valuable time that students would have gotten their regular teaching in order to subject them to a teaching demo, which they know doesn’t matter in the long run.

And of course, this sort of demo interrupts the teaching plans of the regular instructor. Now that instructor has to hang around for the length of the time of the demo letting their attention wander, just like the students. And then the instructor has to go back to their regular class, out of which half an hour or longer has already been squandered.

Furthermore, whatever evaluations are garnered from the teaching demo are not exactly trustworthy. There is evidence that course evaluations (conducted after an entire semester) are biased against women and minority professors. And mind you, that’s after an entire semester—how on Earth can one expect a 25- to 35-minute demo evaluation to be unbiased? They most assuredly are not unbiased and are probably reflective of similar biases against minority and women candidates. I’ve been on and chaired several search committees, and have seen some really random comments listed on the demo evaluations. Needless to say, those comments were not germane to the actual situation, in that they provided no useful evidence about the candidate’s teaching ability.

Also, these sorts of teaching demos are especially rough on candidates who have social anxiety or are introverted. Teaching involves building rapport with your students—20 minutes is hardly enough time to do that. It is entirely possible for a candidate to be unfairly assessed based on a tiny sliver of time. A great teacher could have a bad teaching demo, and a poor teacher could have a great teaching demo—how accurate is it to judge someone’s teaching abilities based on a short lecture? Wouldn’t it be more accurate to actually take the time to pore over the candidate’s teaching evaluations instead? Yes, they are prone to error, but it stands to reason they are not as prone to error as a teaching demo. Preferring a teaching demo over a more complete semester-long evaluation is akin to judging a movie from its trailer. A trailer can be great, but the movie may still be terrible. Ditto with teaching demos.

Alternatives to Teaching Demos

I propose some alternatives to teaching demos. The first is to include a small teaching portion in the job talk itself. Give the candidate the leeway to talk about his or her teaching philosophy and perhaps about their approach to pedagogy. That, when combined with actual semester teaching evaluations, would be far more useful than a 20- or 30-minute demo. Anyone can fake being nice and approachable for 20 or 30 minutes—doing that over the course of a semester is a lot more difficult. Even faculty members who are perceived as rude and unapproachable by their usual students can pass themselves off as wonderful and approachable for a 20-minute window. How they behave throughout the semester is far more useful and predictive information.

Another alternative to a live teaching demo could be to make it asynchronous. Have the candidate record a video lecture of themselves, and then have faculty and students watch the video to rate the candidate on their teaching performance. After all, the goal is to see how the candidate presents and teaches—why not take away the anxiety component of the live demo and instead make it a lot more equitable? Sure, recording a video could be anxiety-provoking in its own right, but it can’t be more anxiety-provoking than a live demo in front of a crowd, can it?

The third alternative to live teaching demos is to open up the candidate’s research presentation to students as well. Far too often, the research presentations are only attended by department faculty members (some of whom have to be reluctantly corralled from their offices by the search committee chair). Opening these presentations up to students would serve a dual purpose, both bolstering the audience numbers and giving the students attending a good idea of how the candidate communicates. This does much the same job that the teaching demo does, but more effectively and efficiently.

Conclusion

To conclude, I am suggesting that we do away with the teaching demos in faculty job candidates’ visits. It is high time that we eliminate useless rituals that we follow just because of tradition. Let’s send teaching demos the way of the dodo.
