Appointlink has been doing some cool stuff customizing SharePoint for a while.  Check out thier new course evaluation component.

The SharePoint Online Course Evaluation Component was designed to improve the current process to generate Instructor and Course Evaluation reports for each semester. This application allows schools to eliminate the paper based method of distributing and gathering student assessments. Derived from student surveys, this application allows students to complete course assessments via a SharePoint Portal and provide an administrative summary report for each individual course as well as a summary report for all courses.
