I am happy to see emphasis placed on value-added learning. I use this when demonstrating to students the importance of frequent source citation in their papers. 

For instance, early on in the term, when students do not cite frequently, I dock points substantially, so that they become aware of this critical factor. As they progress throughout the course, though, and learn how to cite properly, I apply the value-added approach, realizing that, had they been given their Week 1 assignments now, they would have cited sources frequently and otherwise properly.

The concept of value-added eduation, one of many examples of things I have long done but had never identified by professional jargon, is a useful one indeed.
