Digital scaffolding

Earlier this week at the Open EdTech Summit in Barcelona, I spent some time with Professor Paul Kirschner of the Open University of the Netherlands. During one of our creative thinking sessions (see yesterday's post) Paul came up with an idea for the support of online learners which I promptly gave a name to. In this post I am briefly going to outline the concept of Digital scaffolding.

As the name indicates, the concept is based on a social constructivist perspective, loosely on the ideas of Lev Vygotsky's Zone of Proximal Development (ZPD). Jerome S Bruner took the idea onwards, by proposing scaffolding as a means of fading support as learners become more expert and independent. These are fairly familiar concepts to most people in education, and simply involves learners being supported to achieve a level of competence or knowledge which goes beyond what they could otherwise achieve on their own. Generally the idea when first expounded, was descriptive of human support. Now, with the advent of digital technologies and intelligent agent software, the concept can be extended.

The problem is this - many learners enter the somewhat 'cold digital wasteland' of online learning with no immediate signposts or recognisable help. Sure, there are FAQ pages and help call numbers, and supposedly a tutor who can provide online support. But how about learners coming into the online environment at exactly the point where they can be challenged and motivated enough to press onwards, but not to the point where they quickly lose impetus and crash out of the programme? How do we use digital media to ensure that learners are challenged just enough within their ZPD and how can we scaffold their learning so they can maintain their progress through their course of studies?

Paul and I believe that intelligent agents and/or expert tutor support can provide this type of digital scaffolding. We will no doubt be working on this idea in the coming year or two to develop it further into a concrete proposition. But that's the germ of the idea. Let us know what you think.
