Last Thursday, I was supposed to teach a class on technology strategy for a bachelor program at the University of Oslo. That class has been delayed for a week and (obviously) moved online. I thought about doing it video conference, but why not make a video, ask the students to see it before class? Then I can run the class interactively, discussing the readings and the video rather than spending my time talking into a screen. Recording a video is more work, but the result is reusable in other contexts, which is why I did it in English, not Norwegian. The result is here:
To my teaching colleagues: The stuff in the middle is probably not interesting – see the first two and the last five minutes for pointers to teaching and video editing.
For the rest, here is a short table of contents (with approximate time stamps):
- 0:00 – 2:00 Intro, some details about recording the video etc.
- 2:00 – 27:30 Why technology evolution is important, and an overview of technology innovation/evolution processes
- 6:00 – 9:45 Standard engineering
- 9:45 – 12:50 Invention
- 12:50 – 15:50 Structural deepening
- 15:50 – 17:00 Emerging (general) technology
- 17:00 – 19:45 Substitution
- 19:45 – 25:00 Expansion, including dominant design
- 25:00 – 27:30 Structuration
- 27:30 – 31:30 Architectural innovation (technology phases)
- 31:30 – 31:45 BREAK! (Stop the video and get some coffee…)
- 31:45 – 49:40 Disruption
- 31:45 – 38:05 Introduction and theory
- 38:05 – 44:00 Excavator example
- 44:00 – 46:00 Hairdresser example
- 47:00 – 47:35 Characteristics of disruptive innovations
- 47:35 – 49:40 Defensive strategies
- 49:40 – 53:00 Things take time – production and teaching…
- 53:00 – 54:30 Fun stuff
This is not the first time I have recorded videos, by any means, but it is the first time I have created one for “serious” use, where I try to edit it to be reasonably professional. Some reflections on the process:
- This is a talk I have given many times, so I did not need to prepare the content much – mainly select some slides. for a normal course, I would use two-three hours to go through the first 30 minutes of this video – I use much deeper examples and interact with the students, have them come up with other examples and so on. The disruption part typically takes 1-2 hours, plus at least one hour on a specific case (such as the steel production). Now the format forces me into straight presentation, as well as a lot of simplification – perhaps too much. I aim to focus on some specifics in the discussion with the students.
- I find that I say lots of things wrong, skip some important points, forget to put emphasis on other points. That is irritating, but this is straight recording, not a documentary, where I would storyboard things, film everything in short snippets, use videos more, and think about every second. I wanted to do this quickly, and then I just have to learn not to be irritated at small details.
- That being said, this is a major time sink. The video is about 55 minutes long. Recording took about two hours (including a lot of fiddling with equipment and a couple of breaks). Editing the first 30 minutes of the video took two hours, another hour and a half for the disruption part (mainly because by then I was tired, said a number of unnecessary things that I had to remove.)
- Using the iPad to be able to draw turned out not to be very helpful in this case, it complicated things quite a bit. Apple’s SideCar is still a bit unpredictable, and for changing the slides or the little drawing on the slides I did, a mouse would have been enough.
- Having my daughter as audience helps, until I have trained myself to look constantly into the camera. Taping a picture of her or another family member to the camera would probably work almost as well, with practice. (She has heard all my stories before…)
- When recording with a smartphone, put it in flight mode so you don’t get phone calls while recording (as I did.) Incidentally, there are apps out there that allow you to use the iPhone as a camera connected to the PC with a cable, but I have not tested them. It is easy to transfer the video with AirPlay, anyway.
- The sound is recorded in two microphones (the iPhone and a Røde wireless mic.) I found that it got “fatter” if I used both the tracks, so I did that, but it does sometime screw up the preview function in Camtasia (though not the finished product). That would also have captured both my voice and my daughter’s (though she did not ask any questions during the recording, except on the outtakes.)
- One great aspect of recording a video is that you can fix errors – just pause and repeat whatever you were going to say, and the cut it in editing. I also used video overlays to correct errors in some slides, and annotations to correct when I said anything wrong (such as repeatedly saying “functional deepening” instead of “structural deepening”.) It does take, time, however…
My excellent colleague Ragnvald Sannes pointed out that this is indicative of how teaching will work in the future, from a work (and remuneration) perspective. We will spend much more time making the content, and less time giving it. This, at the very least, means that teachers can no longer be paid based on the number of hours spent teaching – or that we need to redefine what teaching means…
