I have really enjoyed following the recent argy bargy between Larry Sanger and Steve Wheeler. From a learning practitioner’s point of view, it raises issues of pedagogy, instructional design, and perhaps even epistemology.
Having said that, I think it all boils down to the novice-expert principle. As a novice, you don’t know what you don’t know. Thankfully, an expert (the teacher) can transmit the necessary knowledge to you quickly and efficiently. In eduspeak, you benefit from “scaffolding”.
Then, after you have acquired (yes – “acquired”) a foundational cognitive framework, I suggest a constructivist approach would be appropriate to expand and deepen your knowledge. In other words, now you know what you don’t know, you can do something about it.
My sector of practice is corporate rather than K-12, but I would assume that because the learners are children, their level of experience and prior knowledge is limited. Hence, having the basic concepts explained up front is a perfectly reasonable teaching strategy.
I wonder, though, whether conversation (online or otherwise) would indeed be a useful technique after the basics have been bedded down? Perhaps the last third or so of the class could be devoted to discourse facilitated by the teacher? Or assigned to participation in a district-wide online discussion forum? (Moderated, of course, by teachers and class nerds.)
Or – more likely – I’m exposing my ignorance of the logistics of managing a classroom.
My point is that constructivism can complement, rather than substitute, instructivism. This is something that I have argued for previously.
My secondary point is that I am quite getting over the Twitterati’s tendency to devalue the role of the expert in education. Not only is the expert aware of the important facts, but they can also impart their meaning and context.
Googling ability does not a scholar make.
