The Education Cpmmission of the States will present its James Bryant Conant award to Willism Sanders. Sanders is a pioneer of VAM (also known as value-added measurement or modeling).
VAM is probably the single worst feature of corporate reform, the one that is most likely to demoralize teachers, lead to early retirements, and to the decline in new recruits to teaching. Sanders promotes the idea that teachers can be evaluated by the test scores of their students. He pioneered VAM in Tennessee in the late 1980s and today it is a widely used methodology, even though Sanders has copyrighted his methods; it is proprietary and other researchers are not allowed to understand how it works.
Although Sanders’ team markets his product with grandiose claims, one need only look at Tennessee to see that it is not near the top of NAEP. After 30 years of VAM, what does Tennessee have to show for its reliance on high-stakes testing? Who would call Temnessee today a national model?
Audrey Amrein-Beardsley describes Sanders:
“VAMs were first adopted in education in the late 1980s, when an agricultural statistician/adjunct professor [emphasis added, as an adjunct professor is substantively different than a tenured/tenure-track professor] at the University of Knoxville, Tennessee – William Sanders – thought that educators struggling with student achievement in the state should “simply” use more advanced statistics, similar to those used when modeling genetic and reproductive trends among cattle, to measure growth, hold teachers accountable for that growth, and solve the educational measurement woes facing the state at the time by doing so. It was to be as simple as that….”
Chalkbeat, which covers education issues in Tennessee, recognizes that VAM is very controversial:
“As per the article: “Hailed by many who seek greater accountability in education, [Sanders’s] TVAAS continues to be a topic of robust discussion in the education community in Tennessee and across the nation. It has been the source of numerous federal lawsuits filed by teachers who charge that the evaluation system—which has been tied to teacher pay and tenure—is unfair and doesn’t take into account student socio-economic variables such as growing up in poverty. Sanders maintains that teacher effectiveness dwarfs all other factors as a predictor of student academic growth.”
Amrein-Beardsley is stunned that ECS is giving this honor to a man who tried to turn teacher evaluation into a “science” comparable to producing crops. She wonders whether angry teachers might picket the ECS meeting in Denver in late June.

VAM is a simple answer to a complex and nuanced question. It has been enormously appealing to those looking for a quick fix. Unfortunately for students, teachers and public education in general, policy makers have ignored the input of educators, statisticians and scholars, who have questioned the validity of VAM and the flawed tests currently being inflicted on the students.

I saw that announcement and had the same reaction.
ETS is doing some reputational damage to itself in honoring the work of this statistician who thought there is every reason to his statistical toolkit–designed to improve the productivity of seeds, sows, and cows by generic engineering– to measure and thereby improve the productivity of teachers in raising the test scores of their students. The Sanders-developed and proprietary EVASS is used to stack rank teachers in Ohio and other states, EVASS is marketed by SAS. There are big bucks in this rank and yank system.

One way of fighting back is letters to the editor. Yesterday I posted a preliminary letter of well over 300 words to this blog. Today I have edited it. Not final, I will continue to work on it.
Some of you may wish to view this, write your own and submit it. If enough people do this it MAY make a difference.
These are only MY views. I omit many adjectives etc in order to get the most ideas into the shortest space, important for letter writing as most papers have a small word limit.
Bottom lines. Educators, public schools, search for truths utilizing scholarly, in depth research. Corporations, corporate schools; making money. Corporate media, corporate agenda.
Example: Climate change; 97% of world’s best scientific minds proclaim it human induced, major catastrophe. Media; promote carbon corporation views.
Media; who‘s leading whom, political horse racing . Politicians assertions printed factually unchecked.
Inadequate media research results: Iraq war; trillions tax payer money lost, death, misery, homelessness ad nauseum: unexamined bank problems; bank failures, depression: Gulf of Tonkin‘ Viet Nam war exploded.
Fundamentally critical problems? Constitutional freedom guarantees drastically diminish. Middle class disappearing, upper 1% siphons national largess. Perpetual war promoted, diplomacy questioned. Plutocracy supplants democracy. Peoples interests succumb, CEOs expand.
Corporate media? Push corporate agenda.
Public schools denigrated, castigated, failures. Equating societal problems, political failures with school failures, unexamined. Our best schools compared with other nations; unexamined, just poorer schools. Corporate schools failures, tax payers paying more for poorer results, extremely poor media reporting.
Preferability? Corporations, politicians provide their “truths”, test materials; grading schools, teachers by students assimilation of, regurgitating their “facts“. Schools formerly; scholarly in depth research of humankind’s best minds compiled by trained educators? Education, ever searching for better understandings or political dogma impositions?
Historically, our nation’s public schools have always innovated, searched for better teaching methodology? Failing fads quickly disappeared.
Politicians always prescient? Sputnik, we must emulate the great Russian schools. Etc.
Tests alone indicators of success? Tests which virtually anyone can pass, can fail? Easily constructed? Proving?
Vitally important questions: are honesty, integrity etc equally valid educative goals as test scores? Does inordinate testing promote, hinder these goals?
Are children humanoids for CEO exploitation or human beings, to be educated to their highest potential, nurtured for democracy?
Our public schools helped build this nation’s greatness?
Which, corporate mentality or in depth scholarship?

As the President of the Board for the So. Ca Regional Occupational Center in the late 1990’s, Torrance, Ca, it was decided— before I was on their Board— by the administration to ‘let’s reward’ the ‘good’ teachers approach with more $$$.
All it did was create anger among the teachers. And it was NEVER fair.
Positive reinforcement can be accomplished in many ways and this is NOT the way.
Everyone has to stop bashing teachers, although I must say, it is a good way to shift the blame rather than to accept responsibility for issues and problems that a teacher never created.

“Sanders maintains that teacher effectiveness dwarfs all other factors as a predictor of student academic growth.”
American Statistical Association noted in the VAM position paper that “Most VAM studies find that teachers account for about 1% to 14% in the variability in test scores, and that the majority of the opportunities for quality improvement are found in the system level conditions.”
So, who you gonna believe? America’s premier statistical association? Or some guy who thought it would be clever to apply a statistical model invented for cattle to teachers?

Circular reasoning. Produce increments in test scores year to year and you will be judged effective and the increments in test scores you produce will be predictors of your effectiveness.

“it is proprietary and other researchers are not allowed to understand how it works.”
One of the sure signs of a crackpot.
It’s actually an item (#20) on John Baez’ “Crackpot Index”
“20 points for talking about how great your theory is, but never actually explaining it. ”
…which gives Sanders a crackpot index of 25 right off the bat since there’s a 5 point “starting credit”.
he also gets points for other stuff as well, of course
1 point for every statement that is widely agreed on to be false.
2 points for every statement that is clearly vacuous.
3 points for every statement that is logically inconsistent.
5 points for each such statement that is adhered to despite careful correction.
The index was designed for physics “theories”, but works for crackpot teacher evaluation theories derived from cattle growth models as well
