I really do think that the Personal Knowledge Managment is the e-learning road we are on. With the Web 2.0 (whatever that really is), with innovations in learning theory, with disruptions in the structures of education (we’ve got a teacher strike on in BC). It’s all coming to a head. Yes, public education practices are a freighter, and hard to get to change course. But it will happen. And it will happen through self-directed learning initiatives. And a part of all this is going to be online reputation managment. So credentials will no longer matter, only what we can do, what we know and that we have a reputation to succeed. Again, not if, but when…

I wonder where things are going with Learning Management Systems (LMS). We’ve got a merger going on with two of the incumbents; Blackboard and WebCT. And both of these incumbents have systems that were developed during Web 1.0. And the Web 2.0 seems to be building steam. The learning theories to support cognitive flexibility and related theories are growing in depth and acceptance. And we have LMS that are targeting these new theories. Moodle is one such LMS and after taking a read of moodles proposed future, it get you thinking.
