Metrics that Matter: Dreaming Big

In a perfect world, I'd choose to track the following:

• Acts of confusion--when did students click on the wrong thing or get lost because they didn't understand the directions or the interface? This unnecessarily increases the time the course takes.
  
• Acts of skimming--what parts of the screen are they reading, glossing over completely, etc.? Essentially, some way to find out what text is unnecessary to help students complete the course successfully
  
• Technical failures--to what extent is a bad internet connection or other mechanical failures affecting learning? We tend to experience this as a group when teachers use certain technology or media in the classroom and it can be very compromising, but how interruptive is it when your entire context for learning is online?
• Connections to other internet sites--is the student simultaneously on wikipedia, facebook, the OED, etc. as they complete the course? What are they doing right before and right after they work on their course? This would probably require Big Brother style surveilance but boy, wouldn't it be interesting?
