Value-Added; a start

Teachers,

I have rounded up a few articles that inform you about 'value-added' systems of evaluation.  One point to clarify, though.  I was slightly off in my general description of the process (last night in class), to save time.  Students' scores compared to averaged students' scores is not the metric; changes in students' test scores are compared to average changes in students' test scores.  So, the rate and direction of change is compared to a mean rate of change.

Sorry to muddy an already murky concept.  As you read, feel free to email questions (or submit them to Ask Us Anything).  Thanks.
