I am a college instructor learning about online pedagogy and spent several hours this past week reviewing the materials at this site. Published in 2001, this site appears to have been last updated in May 2003. The quality of the content is excellent. There are many resources for learning available at this site and with some guidance from the instructor, students' learning should most certainly be enhanced. Overall, the materials are easy to use, particularly the "Related Exhibits" that accompany four of the documentary segments. The interactive components and "exhibits" for each subject area are subdivided and presented in a way that facilitates the user's understanding of the major ideas and concepts. Also helpful is the online glossary ("Resources"), the Hominid Profiles pop-up screens, and links to "Related Resources" (books, articles, and Web sites).
First time users might benefit from an instructor's overview of the site before they access it themselves, although orientation to the site takes only 10-20 minutes. Unfortunately, I did have technical difficulties at this site: I was never able to watch/hear all of the taped segments. I was able to watch one segment of the documentary and then parts of other segments; likewise, I was not able to hear all or part of the audio segments.
