Archives for category: VAM (value-added modeling)

A decade ago, Richard Phelps was assessment director of the District of Columbia Public Schools. His time in that position coincided with the last ten months of Michelle Rhee’s tenure in office. When her patron Adrian Fenty lost the election for Mayor, Rhee left and so did Phelps.

Phelps writes here about what he learned while trying to improve the assessment practices of the DC Public Schools. He posts his overview in two parts, and this is part 1. The second part will appear in the next post.

Rhee asked Phelps to expand the VAM program–the use of test scores to evaluate teachers and to terminate or reward them based on student scores.

Phelps described his visits to schools to meet with teachers. He gathered useful ideas about how to make the assessments more useful to teachers and students.

Soon enough, he learned that the Central Office staff, including Rhee, rejected all the ideas he collected from teachers and imposed their own ideas instead.

He writes:

In all, I had polled over 500 DCPS school staff. Not only were all of their suggestions reasonable, some were essential in order to comply with professional assessment standards and ethics.

Nonetheless, back at DCPS’ Central Office, each suggestion was rejected without, to my observation, any serious consideration. The rejecters included Chancellor Rhee, the head of the office of Data and Accountability—the self-titled “Data Lady,” Erin McGoldrick—and the head of the curriculum and instruction division, Carey Wright, and her chief deputy, Dan Gordon.

Four central office staff outvoted several-hundred school staff (and my recommendations as assessment director). In each case, the changes recommended would have meant some additional work on their parts, but in return for substantial improvements in the testing program. Their rhetoric was all about helping teachers and students; but the facts were that the testing program wasn’t structured to help them.

What was the purpose of my several weeks of school visits and staff polling? To solicit “buy in” from school level staff, not feedback.

Ultimately, the new testing program proposal would incorporate all the new features requested by senior Central Office staff, no matter how burdensome, and not a single feature requested by several hundred supportive school-level staff, no matter how helpful. Like many others, I had hoped that the education reform intention of the Rhee-Henderson years was genuine. DCPS could certainly have benefitted from some genuine reform.

Alas, much of the activity labelled “reform” was just for show, and for padding resumes. Numerous central office managers would later work for the Bill and Melinda Gates Foundation. Numerous others would work for entities supported by the Gates or aligned foundations, or in jurisdictions such as Louisiana, where ed reformers held political power. Most would be well paid.

Their genuine accomplishments, or lack thereof, while at DCPS seemed to matter little. What mattered was the appearance of accomplishment and, above all, loyalty to the group. That loyalty required going along to get along: complicity in maintaining the façade of success while withholding any public criticism of or disagreement with other in-group members.

The Central Office “reformers” boasted of their accomplishments and went on to lucrative careers.

It was all for show, financed by Bill Gates, Eli Broad, the Waltons, and other philanthropists who believed in the empty promises of “reform.” It was a giant hoax.

Jan Resseger read Valerie Strauss’s hopeful column about a possible end to America’s obsession with standardized testing, and wrote about how this testing has warped American education into a punishing regime, rather than an environment of nurturing , growth, caring, compassion, and human development.

Jan reviews some of the most important ways in which test scores have been used to punish students, teachers, principals, and schools, even school districts.

Enough is enough.

The Wall Street Journal, which has a teacher-bashing, union-hating pro-privatization editorial board, published an editorial warning about the dangers of policing the police.

The editorial included these sentences.

“There’s a case for police reforms, in particular more public transparency about offenses by individual officers. Union rules negotiated under collective bargaining make it hard to punish offending officers, much as unions do for bad public school teachers. By all means let’s debate other policies and accountability in using force.”

So, police brutality is the union’s fault. And killer cops are just like those “bad teachers” whose students don’t get high test scores. Clearly, the WSJ didn’t get the memo about the consistent failure of test-based accountability as a means of evaluating teachers.

Do I detect a false equivalency?

Other nations have police unions and a minuscule number of police killings, compared to the U.S. And since when did low test scores become comparable to a brazen act of crushing a man’s windpipe?

Say this for Eric Hanushek: He never gives up on his obsession with paying teachers more if their students get higher test scores. Arne Duncan built this concept into the requirements of his disastrous Race to the Top” program, which caused almost every state to adopt a teacher evaluation plan in which student test scores played a significant role. Harvard economist Raj Chetty wtote a highly-publicized paper with two colleagues, claiming that one good teacher (who raised test scores in the early grades) would raise lifetime incomes (by about $5 a week), reduce pregnancies, and be a life-changer. President Obama cited Chetty in his 2012 State of the Union address, but efforts to turn the theory into reality fell flat. (Read more about this catastrophe in SLAYING GOLIATH.) In fact, every state that imposed value-added measurement learned that it discouraged teachers from teaching in high-needs schools, where their chance of getting a big test score gain was reduced. It did not produce any of the promised benefits.

But forget about reality! Let’s stand by the theory. Hanushek’s new venture at the conservative Hoover Institution is joined by Christopher Ruszkowski, who served as Commissioner of Education in New Mexico after the resignation of Hanna Skandera (who previously worked for the Hoover Institution, Jeb Bush and Arnold Schwarzenegger). After eights years of “reform” leadership, New Mexico remained mired at the bottom of NAEP. The state had a harsh, test-based teacher evaluation plan, but the union fought it in court, it was enjoined by a judge, and the New Democratic Governor scrapped it as one of her first executive actions. New Mexico has one of the highest proportions of students living in poverty, but Republican state leaders ignored that inconvenient fact. After a decade of consistent failure, we can safely put test-based teacher evaluation into the category of a Zombie idea. Dead but still stalking the land.

NEWLY FORMED HOOVER EDUCATION SUCCESS INITIATIVE RELEASES PAPER ON TRANSFORMING TEACHER COMPENSATION

Four education policy papers to be released in 2020—addressing how states should consider transforming education in the decade ahead.

STANFORD, CA. (January 30th) – As state legislative sessions begin around the country, the Hoover Education Success Initiative (HESI), a new research program at Stanford University’s Hoover Institution, has released “The Unavoidable: Tomorrow’s Teacher Compensation”—a policy briefing on the important connections between teacher compensation systems and student achievement outcomes. The research-based policy paper includes both a summary of findings and practical recommendations for policymakers.

The paper highlights often overlooked areas for attention including shifting overall compensation from retirement into salaries, ending the practice of paying for advanced degrees that do not yield changes in student outcomes, addressing teacher shortages in a targeted fashion instead of generally, and paying teachers more when they are effective in higher-need schools.  The paper concludes that teachers’ salaries should be significantly increased, but that students will not make achievement gains unless salaries are also linked to teacher quality.

“We need to pay teachers competitively, which we are not doing now,” said Dr. Eric Hanushek, author of the policy synthesis. “But just increasing compensation without recognizing teacher effectiveness is unlikely to lead to improved student outcomes. We should bundle together better pay with a serious recognition of just how important effective teachers are when it comes to influencing student achievement.”

“While we have spent much of the last year reviewing and synthesizing the research, the next phase of our work turns to helping states implement the policy ideas,” said Christopher N. Ruszkowski, executive director of HESI. “There is overwhelming evidence that nothing matters more than teacher quality, and state legislatures and governors should take strong action. Neglecting this responsibility causes harm to our students that may not be immediately visible today but will certainly be reflected in our students’ lives and in our economy tomorrow.  It’s a tough issue and it may feel like something we can avoid, but it will catch up with us.”

About the Hoover Education Success Initiative

With passage in 2015 of the Every Student Succeeds Act (ESSA), states are again in charge of American education policy. To support them in this undertaking, the Hoover Education Success Initiative (HESI), launched in 2019, seeks to provide state education leaders with policy recommendations that are based upon sound research and analysis.  HESI hosts workshops and policy symposia on high-impact areas related to the improvement and reinvention of the US education system. The findings and recommendations in each area are outlined in concise topical papers.

The leadership team at HESI engages with its Practitioner Council, formed of national policy leaders, and with interested state government leaders. HESI’s ultimate goal is to spark innovation and contribute to the ongoing transformation of the nation’s K-12 education landscape, thus improving outcomes for our nation’s children.

Audrey Amrein Beardsley is one of the leading experts in the nation in the field of value-added assessment and also one of the nation’s leading skeptics of the claim that teacher “effectiveness” can be measured by the test scores of their students.

Recently, a study was published by economists that purported to measure the effect of teachers’ on their students’ height. The study was a blatant lampoon of VAM (value-added modeling or measurement).

It turns out that I was one of about 25 people who promptly forwarded it to Amrein-Beardsley.

She reviewed the study here. 

Beardsley reminds us of a paper written by economist Jesse Rothstein nearly a decade ago in which he lacerated VAM by showing that it could be twisted to show the effect of teachers on students’ past achievement, a feat that is clearly absurd.

When a policy idea like VAM becomes the target of satire, you know that it is well and truly dead. Now, if only someone would tell the state legislatures that.

A group of scholars collaborated to write a paper published by the National Bureau of Economic Research that studies how teachers affect student height. It is a wonderful and humorous takedown of the Raj Chetty et al thesis that the effects of a single teacher in the early grades may determine a student’s future lifetime earnings, her likelihood graduating from college, live in higher SES neighborhoods, as well as avoid teen pregnancy.

When the Chetty study was announced in 2011, a front-page article in the New York Times said:

WASHINGTON — Elementary- and middle-school teachers who help raise their students’ standardized-test scores seem to have a wide-ranging, lasting positive effect on those students’ lives beyond academics, including lower teenage-pregnancy rates and greater college matriculation and adult earnings, according to a new study that tracked 2.5 million students over 20 years.

The paper, by Raj Chetty and John N. Friedman of Harvard and Jonah E. Rockoff of Columbia, all economists, examines a larger number of students over a longer period of time with more in-depth data than many earlier studies, allowing for a deeper look at how much the quality of individual teachers matters over the long term.

“That test scores help you get more education, and that more education has an earnings effect — that makes sense to a lot of people,” said Robert H. Meyer, director of the Value-Added Research Center at the University of Wisconsin-Madison, which studies teacher measurement but was not involved in this study. “This study skips the stages, and shows differences in teachers mean differences in earnings.”

The study, which the economics professors have presented to colleagues in more than a dozen seminars over the past year and plan to submit to a journal, is the largest look yet at the controversial “value-added ratings,” which measure the impact individual teachers have on student test scores. It is likely to influence the roiling national debates about the importance of quality teachers and how best to measure that quality.

Many school districts, including those in Washington and Houston, have begun to use value-added metrics to influence decisions on hiring, pay and even firing….

Replacing a poor teacher with an average one would raise a single classroom’s lifetime earnings by about $266,000, the economists estimate. Multiply that by a career’s worth of classrooms.

“If you leave a low value-added teacher in your school for 10 years, rather than replacing him with an average teacher, you are hypothetically talking about $2.5 million in lost income,” said Professor Friedman, one of the coauthors…

The authors argue that school districts should use value-added measures in evaluations, and to remove the lowest performers, despite the disruption and uncertainty involved.

“The message is to fire people sooner rather than later,” Professor Friedman said.

Professor Chetty acknowledged, “Of course there are going to be mistakes — teachers who get fired who do not deserve to get fired.” But he said that using value-added scores would lead to fewer mistakes, not more.

President Obama hailed the  Chetty study in his 2012 State of the Union address.

Value-added teacher evaluation, that is, basing the evaluation of teachers on the rise or fall of their students’ test scores, was a central feature of Arne Duncan’s Race to the Top when it was unveiled in 2010. States had to agree to adopt it if they wanted to be eligible for Race to the Top funding.

When the Los Angeles Times published a value-added ranking of thousands of teachers, teachers said the rankings were filled with error, but Duncan said those who complained were afraid to learn the truth. In Florida, teacher evaluations may be based on the rise or fall of the scores of students that the teachers had never taught, in subjects they had never taught. (About 70% of teachers do not teach subjects that are tested annually to provide fodder for these ratings.) When this nutty process was challenged inn court by Florida teachers, the judge ruled that the practice might be unfair but it was not unconstitutional.

The fundamental claim of VAM (value-added modeling or measurement) has been repeatedly challenged, most notably by economist Moshe Adler. When put into law, as it was in most states, it was found to be useless, because only tiny percentages of teachers were identified as ineffective, and even the validity of the ratings of that 1-3% was dubious. The use of VAM was frozen by a judge in New Mexico, then tossed out earlier this year by a new Democratic governor. It was banned by a judge in Houston.  A large experiment funded by the Gates Foundation intended to demonstrate the value of VAM produced negative results.

Now comes economic research to test the validity of linking teacher evaluation and student height.

Estimates of teacher “value-added” suggest teachers vary substantially in their ability to promote student learning. Prompted by this finding, many states and school districts have adopted value-added measures as indicators of teacher job performance. In this paper, we conduct a new test of the validity of value-added models. Using administrative student data from New York City, we apply commonly estimated value-added models to an outcome teachers cannot plausibly affect: student height. We find the standard deviation of teacher effects on height is nearly as large as that for math and reading achievement, raising obvious questions about validity. Subsequent analysis finds these “effects” are largely spurious variation (noise), rather than bias resulting from sorting on unobserved factors related to achievement. Given the difficulty of differentiating signal from noise in real-world teacher effect estimates, this paper serves as a cautionary tale for their use in practice.

 

Mercedes Schneider reviews the Gates Foundation’s long and costly list of failed interventions into K-12 schools and points out, quoting the words of the Foundation, that it has never admitted any failure and never apologized.

Gates paid for the interventions but the real cost was borne by teachers and public schools.

He tried breaking up big schools into small schools, convinced as he was that big schools are ineffective, but when the small schools didn’t produce higher test scores, he abandoned that idea.

He prodded Arne Duncan to include the untested of evaluating teachers by the test scores of their students, and he launched his own experiments in seven districts and charter chains. That too was a flop.

He poured uncounted millions into boosting the charter industry, despite the fact that charters do not get different results from public schools when they enroll the same students.

He spent millions promoting a charter law in his home state of Washington, which passed on the fourth state referendum only after he overwhelmed the opposition by spending 16 times as much as they did; the charters he fought so hard for have struggled to get enough enrollment to stay open (four of the original dozen have already folded), and a CREDO evaluation concluded that they don’t get different results than public schools in the state.

Gates provided almost all the funding necessary for the Common Core State Standards, which required districts and states to spend billions of dollars on new tests, new textbooks, new software, new teacher training, new everything.

When the backlash grew against the Common Core, Gates simply didn’t understand it, since he compares education to an electric plug with standard current into which all possible appliances can be plugged in and get power.

This year, the Gates Foundation awarded 476 grants, but only seven went to K-12, mostly to promote charter schools, a passion he shares with the rightwing Walton Foundation and Betsy DeVos and her foundations.

Read the Gates Foundation’s statement that Mercedes includes in her post. You will see that the foundation acknowledges no failures, no errors, no miscalculations. It doesn’t even own its almost total responsibility for CC, nor for its disastrous reception by teachers and the public.

The legacy of Bill Gates: Teachers and principals who were fired based on a phony measure of their “effectiveness.” Schools in black and brown communities closed because of their test scores. A demoralization of teachers, and a dramatic decline in the number of people entering the profession. A national teacher shortage. The elevation of standardized testing as both the means and the ends of all education (tests that were never used in the schools he and his own children attended).

Here are a few things that Bill Gates NEVER funded or fought for: class size reduction; higher salaries for teachers; a nurse and social worker and librarian in every school; higher taxes to support public schools.

Mercedes concludes:

It may be too much to expect Bill Gates to completely exit K12 education. After all, we have been his hobby for years.

But the fewer Gates dollars, the smaller the petri dish.

Unfortunately the lingering effects of his failed experiments continue to ruin schools, such as the value-added measurement of teachers by test scores, still written into law in many states; the Common Core persists, often under a different name to disguise it; and of course charter schools continue to drain students and resources from underfunded public schools.

 

 

Candidates backed by teachers for local school boards in the Denver area (including Denver) won all but one race.

Candidates supported by the teachers’ unions swept school board elections in Denver, Aurora, Douglas County, Littleton, Adams County, Cherry Creek, and Jeffco. The only candidate to lose was in Jeffco.

The “reformers” bold experiment in teacher-bashing has come to an end, at least for now.

Now it is time for the Colorado legislature to eliminate former state senator Michael Johnston’s failed educator evaluation law, which bases 50% of evaluations on test scores. The law was declared a failure even by its supporters but remains on the books. It did not identify “bad” teachers and it did not produce “great teachers, great principals, or great schools,” as Johnston promised in 2010 when his law was passed.

Reformer Van Schoales wrote in Education Week two years ago:

Colorado Department of Education data released in February show that the distribution of teacher effectiveness in the state looks much as it did before passage of the bill. Eighty-eight percent of Colorado teachers were rated effective or highly effective, 4 percent were partially effective, 7.8 percent of teachers were not rated, and less than 1 percent were deemed ineffective. In other words, we leveraged everything we could and not only didn’t advance teacher effectiveness, we created a massive bureaucracy and alienated many in the field.

The problem, he said, was implementation. Every failed reform is dogged by poor implementation. That’s what they said about the Soviet Union and the Common Core.

When the Waltons paid for an analysis of their failure to pass a referendum to expand charter schools in Massachusetts in 2016, their advisors told them that teachers are trusted messengers. The public likes teachers and believes them. They are more credible than out of state billionaires. The Waltons, too, concluded that the problem with their message was poor implementation, not a rejection by the public, which values its public schools (I go into greater detail in my new book SLAYING GOLIATH, which will be published January 21.)

 

 

 

Every year since 2014, Democrats who fervently support the privatization of public schools have gathered at a conference they pretentiously call “Camp Philos.”

https://campphilos.org/

Check the agenda of meetings present and past.

There you will see the lineup of Democrats who sneer at public schools and look on public school teachers with contempt.

These are the Democrats who support the DeVos agenda of disrupting and privatizing public schools.

They are meeting again this year, and they will slap each other on the back for supporting school closures, charter schools, high-stakes testing, evaluating teachers by the test scores of their students, and hiring inexperienced teachers.

They have the chutzpah to call themselves “stakeholders,” although none of them are teachers, parents of public school students, or have any stake in the public schools that enroll 85-90% of all American students. Exactly what do they have a “stake” in?

 

 

Mr. and Mrs. Bill Gates apparently feel they are not winning enough battles in the court of public opinion, so they have created a lobbying organization to promote their ideas in Congress and state legislatures. 

Will the Gates lobby push for Common Core? For more high-stakes testing? For more federal funding for charter schools? For evaluating teachers by the test scores of their students? For more technology in the classroom?

These are but a few of Bill Gates’ failed education initiatives. Has he learned from failure or will he use his C4 lobby to push his failed ideas even more?

Bill and Melinda Gates have launched a lobbying organization to advocate for issues in health, education, and poverty, The Hill reported on Thursday.

The Gates Policy Initiative, which was announced on Thursday, will work with lawmakers on issues such as global health, global development, moving people from poverty to employment, and education for black, Latino, and rural students. The initiative, which will be a 501(c)(4) organization under the US tax code, is independent from the Bill and Melinda Gates Foundation, the billionaire couple’s philanthropic organization.

Rob Nabors, the director of the Bill and Melinda Gates Foundation and the former White House director of legislative affairs during the Obama administration, told The Hill that the Gates Policy Initiative would work in a bipartisan way.

In an article in The Hill, Rob Nabors said the new lobbying organization would reflect the work of the foundation.

Much of what they’ve learned running their foundation will help them through the process of establishing a lobbying shop.

“Probably the most important point for us is similar to the way Bill and Melinda have approached their philanthropic giving and other things that they do. They are interested in learning what works and what doesn’t work,” Nabors said.

He said that if they are not successful in a couple of years, they will “shutter the shop and figure out what else could potentially be done.”

“I think that experimental type of approach, that innovative type of approach, is both relatively unique in this space and embedded into the DNA that Bill and Melinda bring with them,” he said.

Nabors said that when he worked in the Obama White House, his job was often described as the White House chief lobbyist.

“I’m excited to get back into the mix of talking to people specifically about the work that they are doing every day, trying to put bills together that will make people’s lives better,” he said.

He added that Bill and Melinda Gates also bring a unique lens to a lobbying shop.

“They are very data-focused so a number of the types of issues that we will be exploring and the solutions that we are exploring are based on data that we collected from programs that we funded,” he added.
