Could be a landmark paper. At a minimum, it shows that all evaluation methods should completely negate teacher's impact on height. It seriously calls in to question a ton of research that I would have assumed to have been good.
Excellent work by those that wrote the paper.
- datashow 7y agoIt appears to be an important research study, but in the sense of implication to educational policy, not so much. The reason is, for one, the use of value-added measurement does not have a significant role as many would think. There is not a signle state in the U.S. use VAM as a single measure of teacher performance, nor a determinant factor in teacher firing or promotion. It is always mixed with other quantitative and / or qualitative measures (which usually are no better than VAM). The second reason is, the research community has not find a better replacement yet. We always know we cannot directly use student achievement, now we know we cannot trust a more complicated measure such as VAM which takes into account of student history and other factors.
- wtvanhest 7y agoThe world is moving toward multifactor models like VAM. This paper introduces a crucial test to determine whether a VAM is applicable or not.
