I believe it was Gairns and Redman, who put forward the notion that we forget 80% of what we learn. Now, not being a researcher I do not have the evidence to support such a statement but, also, I have little reason to doubt that it is true. So let us for the moment assume that it is true that 80% of what we learn, we forget. That being the case, now imagine the educational potential of a device, a system or a service that enabled learners to retain that 80% (or even a part of that 80% that we forget). The improvement in learning could be enormous and the potential for such a system could be phenomenal for schools and higher education establishments. Not only in schools, of course, but anywhere where learning is important and that, I believe, would also include commercial and social sectors. Now, I believe that such a system could easily be put in place using existing knowledge and technology. Yet what if this is an urban myth, what if we don’t really forget 80% of what we learn? Does that really matter? Who among us can honestly say that they can recall everything they have ever learned? Can we not take it as given that we forget some proportion of what we learn, does it matter whether that proportion is 80%, 90% or even as low as 10%. If learners, their teachers or their trainers, could deploy a service or system that could help retain whatever proportion is forgotten, would it not result in an increase in the amount of learning learned? So, whatever the amount of learning that is forgotten, a service or system that could help learners retain it would be of great potential benefit to schools and other places of learning. As I have said already, I believe that such a system could easily be put in place using current technologies. I don’t want to say more than that at the moment until I have had a chance to explore the matter further. It is just nice, for me, to feel excited once again about the potential of technology to improve education.
