WordPress: Katelyn Ostby. Katelyn gave me permission to share her site a few years ago so I continue to use it has an example of a nicely organized portfolio. Her reflections on revision, and links to scanned first drafts, is an attention to detail that I really appreciated.
Google Site: Callie Bowen. I haven’t said anything about Google Sites before now, but as I was looking for examples, I was reminded of this portfolio. Callie used it two years ago because she knew that her future students in many school districts would have easy access to Google Sites.
Wix: Haily Colbrunn. Hailey used her Wix portfolio for multiple courses, and generally she handled navigation in Wix pretty effectively.
Weebly: Doug Kostecki. I noticed while looking for an example that Weebly users have had trouble with navigation bars, except Doug. His is among the best navigation bars in the history of 458. : )
WordPress again: Abbey Leier’s model from 2013 has some unique features I will let you explore.
