Ferdinand Krauss is preparing for a presentation he'll be giving on designing effective learning objects.
Presentation available here (but requires some form of MS browser, which I don't have handy :-(
UPDATE: If you get the warning: This presentation contains content that your browser may not be able to show properly. This presentation was optimized for more recent versions of Microsoft Internet Explorer. - just click on the "do it anyway" link. It works OK in Safari here, I was just daunted by the "You don't have Explorer" warning...
