John White’s crumbling house of cards – From VAM to worse
These days John White might be needing a hug. It appears all the ill-will and poor decisions making he has sown over the past year is coming home to roost on his doorstep, all at the same time. Support the Louisiana Student Privacy Act Recently we called out White for lying to everyone in the state […]
VAMtastic – what bicycles and teachers have in common
March 17, 2013
To start off this discussion about VAM (value added modeling). The idea that teacher effectiveness can be accurately predicted based mostly on student test scores (or entirely in Louisiana.) and that teacher’s fortunes should be tied to those test scores. That sounds boring so I’ll start off with a really exciting topic, like global warming. It appears […]
Now We Know Why Obama Doesn't Understand VAM
March 16, 2013
Reblogged from deutsch29: In order to truly understand value added modeling (VAM), forget the likes of me and of others who hold degrees in mathematics, or statistics, or measurement. Forget that we offer solid, detailed discussions of the problems of VAM. Forget also that those who formerly promoted VAM, like Louisiana's George Noell, are mysteriously "no longer associated with […]
The simplest argument against the MET Project study
January 19, 2013
In january of 2013, the Gates foundation released the results of their MET, or Measures of Effective Teaching study. I’ve seen a number of articles written explaining why they think the study is flawed or the results are questionable, but I think there is a very easy way to annhiliate the study findings, and the agenda […]
Excellent essay from edweek on why Value Added is junk science
January 19, 2013
Probing the Science of Value-Added Evaluation by R. Barker Bausell, edweek.org January 16th 2013 Value-added teacher evaluation has been extensively criticized and strongly defended, but less frequently examined from a dispassionate scientific perspective. Among the value-added movement’s most fervent advocates is a respected scientific school of thought that believes reliable causal conclusions can be teased […]
Gates Still Doesn't Get It! Trapped in a World of Circular Reasoning & Flawed Frameworks
January 9, 2013
Reblogged from School Finance 101: Not much time for a thorough review of the most recent release of the Gates MET project, but here are my first cut comments on the major problems with the report. The take home argument of the report seems to be that their proposed teacher evaluation models are sufficiently reliable […]
Very Interesting Letter to Wendy Kopp of Teach for America
January 5, 2013
Reblogged from educationclearinghouse: Gary Rubinstein is a Teach for American Alum (TFA). In this letter to TFA's founder and now multi-millionaire Wendy Kopp Rubinstein explains why he is concerned about the misinformation (see: lying) coming out of the mouthpieces of TFA. I find what TFA does to be extremely harmful to existing public schools. They […]

More Evidence on the Shortcomings of “Value-Added” Teacher Evaluations…
November 8, 2012
More Evidence on the Shortcomings of “Value-Added” Teacher Evaluations…. This article from Linda Darling Hammond, a professor of Education at Stanford and a chairman of the National Council’s Board on Testing and Assessment, reinterates some of my earlier points about why Value added is an unstable unreliable hoax that is more influenced by student assignment and […]
The correlation between random temperatures and Value Added Scores
November 2, 2012
I think most people would agree that it makes sense to evaluate people on the job they are doing. I think it is safe to say most people appreciate valuable feedback and constructive criticism. (Well probably not my wife, or myself so much, but stick with me here.) Ideally, if you are going to be […]
