I read some excellent posts and comments this week by Jakob Heidbrink, where he explains the friction he has encountered with the sudden shift to e-learning. More specifically, he described the agonizing process of recording his lectures and how he spent eleven hours to record a 60-minute lecture. Heidbrink is correct in his analysis regarding the required time. I usually say that it takes 10X the time to record and post process a lecture (video editing), compared to just giving it in the classroom. I suspect most teachers that have tried this route will agree with the observation. However, it sounds to me like Heidbrink suffers from the “perfection equals paralysis” condition (also common among engineers). The primary reason for the 10X increase in time he explains, is that he re-records over and over because he stumbles upon words, scratch his nose, cough, and so on – basically just being human. He claims that when a teacher does this in the classroom it is acceptable, but on a recorded lecture such mistakes are not allowed. I disagree and here’s my proposed solution.
Read MoreWhen I do my university courses, I usually reserve the last five minutes of the final lecture for course evaluation. I have found that the most valuable method is to keep it simple. I ask the class to write down on a small anonymous paper note one (1) thing that was good about the course, and one (1) thing that they wish I do next year. This is a powerful method, because when you are forced to give just one answer, you tend to choose the one at the top of your mind. The most important. On one of the notes I read “I wish that you would record the lectures, so we can go back and repeat them”. When I read those words, it felt like a bolt of lightning had struck my head. Of course! Why hadn’t I thought of that? I am doing the lectures anyway, so why not add a camera and a lapel microphone and start recording them? If you are reading this post, old student who wrote that note, I salute you. That little note back in 2017, planted the seed of a powerful idea and you have helped hundreds of people by now with their studies in acoustics, and the number is growing. I cannot thank you enough.
Read MoreSustainability is often said to rest on three pillars: 1) Ecological, 2) Economical and 3) Social sustainability. When supporting a structure with pillars, we also need a solid foundation, or the pillars might sink into the ground. In today’s post, I explore what this foundation might look like. The foundation should consist of eternal values. Two such values instantly come to my mind: Beauty and Education. The primary difference between these two eternal values and the three pillars, is that the three pillars need to be optimally balanced against each other over time as the facts on the ground varies, whereas beauty and education unconditionally strengthens all three pillars at once.
Read MoreYesterday, I livestreamed and published the final lecture in my introductory course in building acoustics. When the dust had settled, I realized that I have never ever felt such a sense of meaning, in anything I have done in my professional career. There has been a lot of friction along the way, especially with technology. Yesterday’s lecture was a personal record in IT problems. First, I did not click the right button when the stream started, so I accidentally presented the first ten minutes of the lecture to an audience that could not see or hear me, and thus had to start from the beginning again. And then my computer crashed in the middle of the lecture and required a reboot. These are major setbacks, but I am amazed by how fast I could just snap back into it and continue the livestream with a genuine smile on my face. As Nietzsche said, “he who has a why, can bear almost any how”. My livestreaming lecture endeavour was a clear example that he was correct.
Read MoreThe other day, I read a book by Michael Pollan, which described how the approach to solving a problem differs between children and adults. A child is more likely to use a novel and unorthodox approach whereas an adult is more inclined to choose a method based on previous experience, that likely works. Therefore, the child is better equipped to solve certain problems that require an unlikely solution. It seems to me that children are higher in openness than their adult selves because they have not developed their fear of failure yet. It is only when you embrace failure that success can truly be achieved. How many times did you fall when you were learning to ride a bicycle? Or who did not sink at first when they were learning to swim?
Read MoreA significant part of my teaching consists of lectures. They often take on the character of a monologue and are therefore the perfect place to start transforming your education to the cloud. Back in 2017 when I was just starting out with online education however, I still felt overwhelmed. There were so many new factors to consider. I wanted to record my lectures with great visual video quality with multiple cameras, crystal clear audio and a screen capture of my slides and preferably live stream it. I have always been interested in technology and find great pleasure in figuring out how things work. But to realize full blown video production in real-time while you are simultaneously giving your lecture was indeed overwhelming. Three years later and that is precisely what I’m doing.
