from the surprise... dept
One of the other lessons I learned in teaching (and in tutoring before that) was that the best way to truly master a subject is to teach it yourself, and have people asking you to explain it back to them. This is why I'm not joking up above when I talk about the possibilities of having certain subjects taught by other students as well. You might think you fully understand a subject, but just wait until people start asking questions (similarly, despite quite a bit of study in the subject, my full "understanding" of certain aspects of information economics didn't become really clear until I had to explain them repeatedly via this blog). And, of course, it need not be students teaching students -- but you could have software designed to act like a "learning" student, where the student has to "teach" the software.It appears that others have had the same idea... and been doing some studies about it. Via TechCrunch, we learn of some new research, by Shizuko Matsuzoe and Fumihide Tanaka at the University of Tsukuba, Japan, that found that when students "taught" a "dumb" robot, they learned a subject much better (in this case, it was Japanese students learning English):
Matsuzoe and Tanaka found that the children did best when the robot appeared to learn from them. This also made the children more likely to want to continue learning with the robot.They note that most traditional "educational" robots tend to work in the other direction... acting as "teachers" for the kids. But those appear to not be nearly as effective as when you flip the relationship. As I found back when I taught, having people continually ask you questions to clarify their own understanding forces you to truly understand the subject yourself at a much deeper level than if you're just a "student."
You can take a look at the full study over here (which, it's great to see, is published under a Creative Commons Attribution 3.0 License). And there are some really interesting findings. First, the difference in performance with and without the robot is pretty significant:
Contrary to our initial assumption, the average percentage of questions answered correctly was in fact higher than the results obtained on the day of the experiment (we predicted that it would have been lower because the children might have forgotten the learned verbs). Subsequent interviews with parents (details in Section 6.3.3) provided us with some clues for this result. Most parents told us that their children appeared to enjoy the experience of teaching the care-receiving robot so much that he or she continued to play the game at home, even after several days, weeks, and wherever similar objects were found.While this is still early research, it's definitely encouraging, and hopefully more people will start to explore similar ideas. Teaching kids by having them teach others could be a really effective way to create a much deeper level of understanding within students, rather than just teaching them to learn by rote.
