I'm a governor of a big FE college, which means I need to keep an eye on issues like value added measures of teachers' or institutions' performance.
Five items have recently caught my attention and I thought that gathered into one place they might be useful to others. [I'll consider adding more if you send them to me.]
The first two are brief rebuttals of work funded by the Bill and Melinda Gates Foundation [PDF] that purports to show that there is year-to-year consistency in the "value" that individual teachers add to learners.
The third is a classy more general piece about the instability of value-added estimates, from the Albert Shanker Institute. The fourth is a recently published article by Schafer and colleagues which challenges commonly held assumptions about value added. Finally there is a short video by the research psychologist Daniel Willingham (yes, the Daniel Willingham cited by Michael Gove in his speech in praise of tests in November 2012 - on which Willingham was himself moved to comment), which summarises the problem with value added in a particularly accessible way.
