I just stumbled back to this thread... we now have some examples to share with you!
These pages include class-wide portfolios plus student-created personal portfolios. This page is a great example: http://cfhsphotography.weebly.com/digital.html. If you scroll down the page you will see student portfolios that the students manage on an ongoing basis. At the very bottom there is a link to student pages that were created for a final exam photography/photojournalism project.
Check out the links for the Critiques too - these are the blog pages.
