While this resource is more of a paper than a presentation, it does accurately convey an overview of the development of three of the contributing theories to instructional design.
I would love to see some updates reflecting some of the theories that have been reconsidered or developed since the paper was written in 1998. I find it particularly helpful that the paper is available for download in both English and Spanish. The generous use of hyperlinks at the beginning of the essay is helpful, and I would like to see hyperlinks used through the essay to help the reader navigate easily back-and-forth within the document.
Another helpful aspect is that the paper links to other papers from the same department, allowing a user to browse additional content that is not necessarily stored in MERLOT. The latest article at the site was from 2008, so I am not sure what this represents for the university department or the maintenance of that particular element of the web site.
