Prototype formative feedback assessment interface

Formative feedback is central to skill learning, but it means a lot of grading.

I recently completed a prototype formative feedback assessment interface. The goal is to reduce the cost of giving formative feedback, by (1) making the workflow faster, and (2) using standardization so that the task can be outsourced.

I'm looking for feedback on the feedback interface (metafeedback?).

There's a video demo at http://youtu.be/2uSCr_liuiI .

(The code uses Backbone.js, which will be part of D8.)

Thnx,
Kieran
