Thanks for posting Allan! I would love to get some instructors on campus using Tableau for assignments.
My thoughts exactly. I've been quiet on here recently, as we've been using Tableau to integrate with the IDEA center (Course, Faculty, Department Head and Administrator evaluations) - I can't post these as examples, as the data is sensitive - but we are looking to integrate with Canvas which has an API - which would allow students to create their own dashboards based on their assignment scores.
On the same subject, are you are of the MOOC movement? I think there could be some synergy there to possibly leverage Tableau as a reporting tool.
