Did Bill Gates waste a billion dollars because he failed to understand the formula for the standard deviation of the mean? Howard Wainer makes the case in the entertaining Picturing the Uncertain World (first chapter with the Gates story free here). The Gates Foundation certainly spent a lot of money, along with many others, pushing for smaller schools and a lot of the push came because people jumped to the wrong conclusion when they discovered that the smallest schools were consistently among the best performing schools. ....... States like North Carolina which reward schools for big performance gains without correcting for size end up rewarding small schools for random reasons. Worst yet, the focus on small schools may actually be counter-productive because large schools do have important advantages such as being able to offer more advanced classes and better facilities. Schools2 All of this was laid out in 2002 in a wonderful paper I teach my students every year, Thomas Kane and Douglas Staiger's The Promise and Pitfalls of Using Imprecise School Accountability Measures. In recent years Bill Gates and the Gates Foundation have acknowledged that their earlier emphasis on small schools was misplaced. Perhaps not coincidentally the Foundation recently hired Thomas Kane to be deputy director of its education programs.Related: Small Learning Communities and English 10.
New York City's standalone middle schools do a worse job educating students than schools that offer kindergarten through eighth grade under one roof, according to a new study to be released Wednesday by researchers at Columbia University. On average, children who move up to middle school from a traditional city elementary school, which typically goes up to fifth grade, score about seven percentiles lower on standardized math tests in eighth grade than those who attend a K-8 school, says Jonah Rockoff, an associate professor at the Columbia Graduate School of Business who co-authored the study. The disparity stems from the toll that changing to a new school takes on adolescents and differences in the sizes of grades, the study says. Typically, K-8 schools can fit fewer children in each grade than standalone middle schools. "What we found bolsters the case for middle-school reform." says Mr. Rockoff, noting that there aren't significant differences in financial resources or single class sizes between the two types of schools. Standalone "middle schools, where kids are educated in larger groups, are not the best way to educate students in New York City." The research culls data for city school children who started in grades three through eight during the 1998-99 school year and tracks them through the 2007-2008 school year, comparing test scores, attendance rates and parent evaluations. Of the student sample, 15,000 students attended a K-8 school versus 177,000 who attended a standalone middle school.The complete paper is available here:
We examine the implications of separating students of different grade levels across schools for the purposes of educational production. Specifically, we find that moving students from elementary to middle school in 6th or 7th grade causes significant drops in academic achievement. These effects are large (about 0.15 standard deviations), present for both math and English, and persist through grade 8, the last year for which we have achievement data. The effects are similar for boys and girls, but stronger for students with low levels of initial achievement. We instrument for middle school attendance using the grade range of the school students attended in grade 3, and employ specifications that control for student fixed effects. This leaves only one potential source of bias--correlation between grade range of a student's grade 3 school and unobservable characteristics that cause decreases in achievement precisely when students are due to switch schools--which we view as highly unlikely. We find little evidence that placing public school students into middle schools during adolescence is cost-effective. One of the most basic issues in the organization of public education is how to group students efficiently. Public schools in the U.S. have placed students of similar ages into grade levels since the mid-1800s, but grade configurations have varied considerably over time. At the start of the 20th century, most primary schools in the U.S. included students from kindergarten through grade 8, while the early 1900s saw the rise of the "junior high school," typically spanning grades 7-8 or 7-9 (Juvonen et al., 2004). More recently, school districts have shifted toward the use of "middle schools," which typically span grades 6-8 or 5-8.1 Interestingly, middle schools and junior high schools have never been popular among private schools.2 The impact of grade configuration has received little attention by economists relative to issues such as class size or teacher quality. There are a few studies which provide evidence that the transition to middle school is associated with a loss of academic achievement, elevated suspension rates, and reduced self esteem (Alspaugh (1998a, 1998b), Weiss and Kipnes, (2006), Byrnes and Ruby (2007), Cook et al. (2008)). There is also a large body of work by educational researchers and developmental psychologists documenting changes in attitudes and motivation as children enter adolescence (Eccles et al. (1984)), and some have hypothesized that instructional differences in middle schools contribute to these changes. However, these studies examine differences between middle school and elementary school students using cross-sectional data, and therefore are unable to reject the hypothesis that differences across students, rather than differences in grade configuration, are responsible for divergent educational outcomes.3 In this study, we use panel data in New York City to measure the effects of alternative grade configurations. Specifically, we focus on variation in achievement within students over time, and examine how student achievement is affected by movement into middle schools. Elementary schools in New York City typically serve students until grade 5 or grade 6, while a smaller portion extend through grade 8; thus most students move to a middle school in either grade 6 or grade 7, while some never move to a middle school. We find that achievement falls substantially (about 0.15 standard deviations in math and English) when students move to middle school, relative to their peers who do not move. Importantly, these negative effects persist through grade 8, the highest grade level on which test data are available.
Five years ago yesterday, the levees broke. Hurricane Katrina flooded roughly 80% of this city, causing nearly $100 billion in damage. The storm forced us to rebuild our homes, workplaces and many of our institutions--including our failing public education system. But from the flood waters, the most market-driven public school system in the country has emerged. Education reformers across America should take notice: The model is working. Citywide, the number of fourth-grade students who pass the state's standardized tests has jumped by almost a third--to 65% in 2010 from 49% in 2007. The passage rate among eighth-graders during the same period has improved at a similar clip, to 58% from 44%. In high school, the transformation has been even more impressive. Since 2007, the percentage of students meeting the state's proficiency goals is up 44% for English and 45% for math. Schools have achieved this dramatic improvement despite serving a higher percentage of low-income students--84%--than they did before the storm. Many of these students missed months or even a whole year of school.
The announcement on Tuesday that Massachusetts has qualified for $250 million in federal grant money under the Obama administration's "Race to the Top" program would seem to validate the state Board of Education's unanimous decision in July to adopt the national standards program. The standards will dictate what students across the country will learn in English and math. Nevertheless, the board's decision still may prove a liability for Gov. Deval Patrick in his bid for re-election in November. Nine other states will share more than $3 billion in grants in this second round of awards. Cape Cod schools look to gain almost $2 million -- all of which will be targeted toward improving pupil performance, particularly in schools where the student achievement gap is significant. It will provide funding to improve teacher training, overhaul failing schools, and will increase accountability by tying test results to teachers.
I have just returned from giving a three-day workshop on student history research papers for English and Social Studies teachers, both high school and middle school, in Collier Country, Florida. They assessed and discussed four high school student research papers using the procedures of the National Writing Board. We went over some of the consequences for a million of our students each year who graduate from high school and are required to take (and pay for) non-credit remedial courses when they get to college. I talked to them about the advantages students have if they have written a serious paper, like the International Baccalaureate Extended Essay, in high school, and the difficulties with both reading nonfiction books and writing term papers which students (and college graduates) have if they have not been asked to do those tasks in high school. It was a diligent, pleasant and interesting group of teachers, and I was glad to have had the chance to meet with them for a few days. They seemed genuinely interested in having their students do serious papers and be better prepared for college (and career). At lunch on the last day, however, I discovered that Florida is a "right to work" state, and that their local union is rather weak, so they each have six classes of 30 or more students (180 students). One teacher is being asked to teach seven classes this year, with 30 or more students in each (210). After absorbing the fact of this shameful and irresponsible number of assigned students, I realized that if these teachers were to ask for the 20-page history research paper which is typical of the ones I publish in The Concord Review, they would have 3,600 pages to read, correct, and comment on when they were turned in, not to mention the extra hours guiding students through their research and writing efforts. The one teacher with 210 students would have 4,200 pages of papers presented to him at the end of term. It made me both sad and angry that these willing teachers, who want their students to be prepared for higher education, have been given impossible working conditions which will most certainly prevent them from helping their students get ready for the academic reading and writing tasks which await them in college (and career).

So most of you may have heard that the LA Times is doing a huge multi-part story about teacher evaluation. One of the biggest parts is a listing of every single public school teacher and their classroom test scores (and the teachers are called out by name). From the article:Though the government spends billions of dollars every year on education, relatively little of the money has gone to figuring out which teachers are effective and why. Seeking to shed light on the problem, The Times obtained seven years of math and English test scores from the Los Angeles Unified School District and used the information to estimate the effectiveness of L.A. teachers -- something the district could do but has not. The Times used a statistical approach known as value-added analysis, which rates teachers based on their students' progress on standardized tests from year to year. Each student's performance is compared with his or her own in past years, which largely controls for outside influences often blamed for academic failure: poverty, prior learning and other factors.Interestingly, the LA Times apparently had access to more than 50 elementary school classrooms. (Yes, I know it's public school but man, you can get pushback as a parent to sit in on a class so I'm amazed they got into so many.) And guess what, these journalists, who may or may not have ever attended a public school or have kids, made these observations:
Here on Jeju Island, famous for its tangerine groves, pearly beaches and honeymoon resorts, South Korea is conducting a bold educational experiment, one intended to bolster opportunity at home and attract investment from abroad. By 2015, if all goes according to plan, 12 prestigious Western schools will have opened branch campuses in a government-financed, 940-acre Jeju Global Education City, a self-contained community within Seogwipo, where everyone -- students, teachers, administrators, doctors, store clerks -- will speak only English. The first school, North London Collegiate, broke ground for its campus this month. While this is the country's first enclave constructed expressly around foreign-style education, individual campuses are opening elsewhere. Dulwich College, a private British school, is scheduled to open a branch in Seoul, the capital, in a few weeks. And the Chadwick School of California is set to open a branch in Songdo, a new town rising west of Seoul, around the same time.
Knowledge is power, but it is not always welcome. The Los Angeles Times just completed an extensive study of how individual teachers have fared at raising their students' math and English test scores in the state's most populous city. The raw data have been available to the L.A. Unified School District for years, but it never bothered to crunch those numbers, let alone share them with parents. The Times has pledged to publish its ratings of 6,000 elementary school instructors. Reaction of the local teachers union? It has called for a "massive boycott" of the Times.
A quarter-century ago, the nation was transfixed by this question: " Where's the beef?" Now, the question we should be asking ourselves about our nation's schools is this: " Where's the rigor?" Or, "Where's the academic beef?" Concerns about the lack of rigor in U.S. schools were renewed recently, when new data were published on how prepared - or not - U.S. high school students are for college. Writing in the Wall Street Journal, Stephanie Banchero said, "New data show that fewer than 25% of 2010 graduates who took the ACT college-entrance exam possessed the academic skills necessary to pass entry-level [college] courses." The story, as reported by many outlets, was that the average ACT score has fallen slightly since 2007. But the real story - and the one that Banchero focused on - is that the vast majority of our high school graduates aren't ready for college or a career. And this holds true even when they follow a supposedly "rigorous" course of study, taking four years of English and three years each of math, science and social studies. It turns out that much of what U.S. schools offer is "rigorous" in name only. Said differently, a distinct lack of academic rigor is de rigueur.Related: A deeper look at local National Merit Scholar Results.
Life expectancy at birth ranges from 80 years in Hawaii to 72 in Washington, DC; and from 83 in Japan to 40 in Swaziland. In vitro fertilisation is available in some regions of the UK within months; in others it takes years. Fill in your own example here, because it is now a commonplace that the price, availability and quality of anything from a nursing home to a good education will vary depending on where you live. I am not sure whether the British complain more about this than anyone else, but we have developed our own term to describe it: the "postcode lottery". For community-minded gamblers there is actually a real postcode lottery, in which prizes are shared between winning ticket-holders and those fortunate enough to have homes on the same street. But for most Britons, the term is a lazy shorthand for the fact that where you live affects what you get. There is a glaring problem with this phrase: while the ticket that gets pulled out of the tombola is chosen at random, the postcodes where you and I live are not. We aren't serfs. If we want to move and we can afford to move, we can move. I live in Hackney, a London borough where crime is high and the schools are poor. If I had a few spare million, perhaps I would move to Hampstead or Chelsea. I do not. People who shop at Harrods expect better food than those who shop at Tesco. Ferraris are faster and sexier than Fords. There are many words to describe this state of affairs, but "lottery" is not the one I would choose.Harford makes an excellent point. It is clearly futile to impose one size fits all approaches, particularly in education. We, as a society are far better off with a diverse governance (many smaller schools/districts/charters/vouchers) and curricular environment.
There's already plenty of chatter about Sunday's LA Times article on the value-added scores of LAUSD teachers, and certainly more to come (comments blowing up here). With access to seven years of math and English scores for hundreds of thousands of 3rd through 5th grade students (under California Public Records Act), the Times hired RAND researcher Richard Buddin to conduct a value-added analysis on LAUSD teachers. Over the next few weeks, and likely beyond that, the Times promises to publish the findings of this analysis in articles and via a full database. For thousands of LAUSD teachers, this means they should expect to see their names and scores in their morning paper. For parents and the rest of the public, it means they will have more information about public school teachers' performance than ever before.
Fion Chan Chui-tung could barely utter a complete sentence in Putonghua or English a year ago. Now, after 12 months at Utahloy International School, a sprawling and pristine international school in Guangzhou, the Hong Kong teen converses effortlessly with her ethnically diverse schoolmates. Fion, 18, is one of a growing number of pupils who have upped sticks and headed north to study. Enrollment of Hongkongers in international schools in Guangzhou and Shenzhen is rising by 5 to 10 per cent a year. Parents who spurn prestigious international schools in Hong Kong in favour of mainland ones cite a list of factors: lower tuition fees, low living costs, a strict teaching regimen and bucolic campuses where not a word of Cantonese is spoken. Fion's mother, Luk Yim-fong, a businesswoman, transferred her daughter from Heung To Secondary School in Tseung Kwan O to Utahloy so that she would not be surrounded by Cantonese speakers. "Although Heung To offers Putonghua classes, all the students speak Cantonese after class," she says. "From my business dealings with multinational corporations like Samsung, even Korean businessmen speak fluent Putonghua. Mandarin is a language my daughter must master in order to thrive in future."
I have two guest columnists today, Patricia and Luis. Their teacher, Michael L. Conners, introduced me to their work. They cannot use their last names here because both are in the United States illegally. Conners was an English as a Second Language teacher at the Columbia Heights Education Center in the District, a public secondary school previously known as Bell Multicultural High School, when he taught these students. In 2008, his class submitted essays to NPR's "This I Believe" radio program. None were selected for broadcast, but Conners thought they represented good examples of student writing and sent them to me. Both of these essays were influenced by the students' research into the laws that restrict their access to college financial aid. Both are entering their senior year, and college is on their minds. I thought this would be an opportunity to show the level of writing for students at an urban high school whose Advanced Placement English program I have often praised. I don't take sides on the issue they raise, but I am interested in how well they raise it. Conners will be teaching at the E.L. Haynes Public Charter School in the District this year. He can be reached at milloydconners@gmail.com.
In June 2010, the Common Core State Standards Initiative (CCSSI) offered the nation two sets of English language arts standards: one set called "college and career readiness anchor standards," and the other, grade-level standards that build towards these anchor standards. With few exceptions, both sets of standards consist of content-empty and culture-free generic skills. Why are they so bereft of substantive content? In large part because they reflect a faulty diagnosis of why many American students are unprepared for authentic college-level work. The misdiagnosis comes from CCSSI's reliance on the results of ACT surveys to guide the development of its standards. Several years ago, ACT surveyed thousands of post-secondary instructors to find out what they saw as the chief problems in their freshman students. Not surprisingly, the chief complaint was that high school graduates cannot understand the college texts they are assigned to read. Without an explanation for its reasoning, ACT leaped to two conclusions: (1) college students are not expected to read enough complex texts when they are in high school; and (2) they are not given enough instruction in strategies or skills for reading complex texts in high school.
I had lunch this summer with a prospective graduate student at the evangelical college where I teach. I will call him John because that happens to be his name. John has done well academically at a public university. Nevertheless, as often happens, he said that he was looking forward to coming to a Christian university, and then launched into a story of religious discrimination. John had been a straight-A student until he enrolled in English writing. The assignment was an "opinion" piece and the required theme was "traditional marriage." John is a Southern Baptist and he felt it was his duty to give his honest opinion and explain how it was grounded in his faith. The professor was annoyed that John claimed the support of the Bible for his views, scribbling in the margin, "Which Bible would that be?" On the very same page, John's phrase, "Christians who read the Bible," provoked the same retort, "Would that be the Aramaic Bible, the Greek Bible, or the Hebrew Bible?" (What could the point of this be? Did the professor want John to imagine that while the Greek text might support his view of traditional marriage, the Aramaic version did not?) The paper was rejected as a "sermon," and given an F, with the words, "I reject your dogmatism," written at the bottom by way of explanation.
When New York state education officials recalibrated test scores this week, hundreds of New York City schools suddenly had vastly fewer children who could be termed "proficient" in math and English. For many schools, the higher bar had barely an effect. For others, it was a devastating blow, revealing a much larger chasm between the city's academic haves and have-nots. Overall, the country's largest school system lost a lot of ground. Last year, nearly 70% of students were considered proficient in English. Now, only 42% are. In math, 54% of city children scored proficient this year, down from 82%. Mayor Michael Bloomberg and his schools chancellor, Joel Klein, stressed this week that the only thing that changed was the definition of "proficient," and that the gains that New York City students have made since they took over control of schools--as evidenced by performance on national tests--are real.
The State Board of Education is voting Monday on adopting national K-12 curriculum standards in a package that includes an obese, unteachable eighth-grade math course. Back in May 2009, Gov. Arnold Schwarzenegger, State Board of Education President Ted Mitchell and Superintendent of Public Instruction Jack O'Connell pledged to adopt the then-not-yet-created national curriculum standards only if they "meet or exceed our own." The pledge these public officials took was wise and honorable. California has K-12 academic-content standards that are widely praised as the best in the nation. For example, the Thomas B. Fordham Institute found on July 21 that California's standards in both English and mathematics are the absolute best in the nation and better than the national standards. Clearly, Fordham's expert reviewers did not agree with the calls we sometimes hear that we must ditch our standards because they are inadequate.
Erasing years of academic progress, state education officials on Wednesday acknowledged that hundreds of thousands of children had been misled into believing they were proficient in English and math, when in fact they were not. The bar for what it means to be "proficient" has now been set substantially higher. For instance, last year more than 77% of New York state students in grades three through eight reached proficiency in state English exams. Under the new standards, only 53% were considered proficient this year. The difference amounts to nearly 300,000 students across the state. "We are facing the hard truth that the gains in the past were simply not as advertised," said Merryl Tisch, the chancellor of the state Board of Regents, during a news conference announcing the new standards. In New York City, the number of students scoring proficient in English fell to 42% this year from 69% in 2009. In math, 54% of city children scored proficient this year, down from 82%. The huge drops across the state raised questions about how much of the academic gains touted in the past several years were an illusion.Related: The WKCE.
Do the languages we speak shape the way we think? Do they merely express thoughts, or do the structures in languages (without our knowledge or consent) shape the very thoughts we wish to express? Take "Humpty Dumpty sat on a..." Even this snippet of a nursery rhyme reveals how much languages can differ from one another. In English, we have to mark the verb for tense; in this case, we say "sat" rather than "sit." In Indonesian you need not (in fact, you can't) change the verb to mark tense. In Russian, you would have to mark tense and also gender, changing the verb if Mrs. Dumpty did the sitting. You would also have to decide if the sitting event was completed or not. If our ovoid hero sat on the wall for the entire time he was meant to, it would be a different form of the verb than if, say, he had a great fall. In Turkish, you would have to include in the verb how you acquired this information. For example, if you saw the chubby fellow on the wall with your own eyes, you'd use one form of the verb, but if you had simply read or heard about it, you'd use a different form.
A tussle over the Jersey City schools superintendent's $280,000-a-year contract is headed for a showdown involving New Jersey's education commissioner, putting a spotlight on one of the state's most troubled school districts. Charles Epps has been superintendent for the past 10 years. Twenty-six of his 37 schools failed last year to make "adequate yearly progress," according to federal standards, and one middle school---where only 32% of children are proficient in English and 25% proficient in math--has fallen short of the federal goal nine years straight. Late last month, the local school board voted to forgo an outside search for a new superintendent and to begin negotiating a new three-year contract with Mr. Epps. That enraged some local activists, who have filed a petition with the state to overturn the board's vote. "There's a window of opportunity to stop rewarding failure," said Steven Fulop, a Jersey City council member who is helping to spearhead the opposition. "Nobody in their right mind would rehire someone who has failing performance without even a cursory look at who else is out there." The petition accuses the school board of failing to give 30 days' notice and opportunity for the public to voice their opinions before the vote.
