Here is the full transcript of serial entrepreneur Michael Bodekaer’s TEDx Talk: Reimagining Education at TEDxCERN conference.
Today, I am going to show you how this tablet and this virtual-reality headset that I’m wearing are going to completely revolutionize science education. And I’m also going to show you how it can make any science teacher more than twice as effective.
But before I show you how all of this is possible, let’s talk briefly about why improving the quality of science education is so vitally important. If you think about it, the world is growing incredibly fast. And with that growth comes a whole list of growing challenges, challenges such as dealing with global warming, solving starvation and water shortages and curing diseases, to name just a few. And who, exactly, is going to help us solve all of these great challenges? Well, to a very last degree, it is these young students. This is the next generation of young, bright scientists.
And in many ways, we all rely on them for coming up with new, great innovations to help us solve all these challenges ahead of us. And so a couple of years back, my cofounder and I were teaching university students just like these, only the students we were teaching looked a little bit more like this here.
And yes, this is really the reality out there in way too many universities around the world: students that are bored, disengaged and sometimes not even sure why they’re learning about a topic in the first place. So we started looking around for new, innovative teaching methods, but what we found was quite disappointing. We saw that books were being turned into e-books, blackboards were being turned into YouTube videos and lecture hall monologues were being turned into MOOCs — massive online open courses.
And if you think about it, all we’re really doing here is taking the same content and the same format, and bringing it out to more students — which is great, don’t get me wrong, that is really great — but the teaching method is still more or less the same, no real innovation there.
So we started looking elsewhere. What we found was that flight simulators had been proven over and over again to be far more effective when used in combination with real, in-flight training to train the pilots. And so we thought to ourselves: Why not just apply that to science? Why not build a virtual laboratory simulator? Well, we did it.
We basically set out to create a fully simulated, one-to-one, virtual reality laboratory simulator, where the students could perform experiments with mathematical equations that would simulate what would happen in a real-world lab.
But not just simple simulations — we would also create advanced simulations with top universities like MIT, to bring out cutting-edge cancer research to these students. And suddenly, the universities could save millions of dollars by letting the students perform virtual experiments before they go into the real laboratory.
And not only that; now, they could also understand — even on a molecular level inside the machine — what is happening to the machines. And then they could suddenly perform dangerous experiments in the labs as well. For instance also here, learning about salmonella bacteria, which is an important topic that many schools cannot teach for good safety reasons.
And we, of course, quiz the students and then give the teachers a full dashboard, so they fully understand where the students are at. But we didn’t stop there, because we had seen just how important meaning is for the students’ engagement in the class. So we brought in game designers to create fun and engaging stories. For instance, here in this case, where the students have to solve a mysterious CSI murder case using their core science skills. And the feedback we got when we launched all of this was quite overwhelmingly positive.
Here we have 300 students, all passionately solving CSI murder cases while learning core science skills. And what I love the most about this is really when the students come up to me sometimes afterwards, all surprised and a little confused, and say, “I just spent two hours in this virtual lab, and I didn’t check Facebook.” That’s how engaging and immersive this really is for the students.
And so, to investigate whether this really worked, a learning psychologist did a study with 160 students — that was from Stanford University and Technical University of Denmark. And what they did is split the students into two groups. One group would only use the virtual laboratory simulations, the other group would only use traditional teaching methods, and they had the same amount of time. Then, interestingly, they gave the students a test before and after the experiment, so they could clearly measure the learning impact of the students.
And what they found was a surprisingly high 76 percent increase in the learning effectiveness when using virtual laboratories over traditional teaching methods. But even more interestingly, the second part of this study investigated what the teacher’s impact was on the learning. And what they found was that when you combined the virtual laboratories with teacher-led coaching and mentoring, then we saw a total 101 percent increase in the learning effectiveness, which effectively doubles the science teacher’s impact with the same amount of time spent.
