As a postscript to my post last week, it's not that I don't think reusable learning objects have a lot to teach us about how e-learning might work. I do. Much of my effort over the last few years has been in some way related to RLOs. It's just that I have a dawning realization that what educational technologists think of when they talk about learning objects is not the same as what lecturers and teachers think. And I don't just mean the old debate about whether a picture is an RLO or whether a course is. I mean something much deeper, about the way people interact with RLOs, what they're for and how they work for us. What works in the real world of teaching and learning, and what doesn't. At some point I think both communities needs to start interoperating.
