Ka’Ching! 2016 US Edtech Funding Totals $1 Billion

The mind of a student today

December 26, 2014 Below is an interesting visual I cam across through a tweet from We Are Teachers. The visual maps out some really intriguing facts about students today. These facts are based on different studies and surveys conducted mainly on US students. I went through this resource and devised this brief synopsis: Minority students attending US schools will make up a majority of all students…

The Best of the Consumer Electronics Show 2016

I’ve returned from the biggest battleground of tech, the Consumer Electronics Show in Las Vegas.

My Intel Basis Peak smartwatch told me that, over four days at CES, I walked 73,376 steps, or 18,344 steps per day. Those steps felt heavier this year because I carried a shoulder bag instead of using a roller bag, per the new security rules at the event. On the plus side, I managed to come back without the nerd flu and without a blister like last year.

I did my best, but that means I still only covered a very small percentage of the 3,000-plus companies spread across 2.4 million square feet of exhibit space at CES. My eyes began to glaze over as I saw the enormous numbers of drones, augmented reality glasses, virtual reality headsets, robots, smart cars, fitness wearables, 3D printers, and smart appliance that were part of the Internet of Things (making everyday objects smart and connected). I have published 63 stories about CES products and events. (I should say, I’ll continue to publish stories from CES over the next couple of weeks). I think this was my 20th CES, though I have lost count.

Inside the bubble of CES, which was attended by an estimated 150,000 people, I didn’t even know the stock market was melting down. CES is the place to look if we want to find the things that are going to save us from economic gloom, although we may have to really look. The global technology industry is expected to generate $950 billion in 2016, down 2 percent from a year ago, with the decline due in no small part to weakness in China. This year, I didn’t see much that was going to save the world economy and overcome the skepticism of natural-born cynics. You could certainly find partisans who will say that virtual reality or the Internet of Things will do that, as both movements have spread well beyond just one or two companies. But it’s a reach to say that these categories have already given us their killer apps.

Sill, I had a lot of fun finding things that I liked, and there was no shortage of these. Without further ado, here’s my favorite technology from CES 2016:

Panasonic Transparent Display

The idea of a transparent display isn’t that new. Big tech companies have been targeting them at retailers for a while. But this week Panasonic showed off a 55-inch television for the living room. The display is embedded in a bookcase, where it can transparently show a kind of trophy case behind the glass. But then it turns to black and shows home portraits. The image swivels to reveal a personalized screen with a weather report or a screen displaying a liquid-like aquarium. And it can even show a television show. The display has micro light-emitting diodes. While the screen is limited, as it isn’t completely transparent, it can display at a resolution of 1080p. This was a glimpse of the future, much like Panasonic’s Magic Mirror from a year ago. And I thought it was a wonderful example of how to make technology blend into the environment of the home.

Eyefluence

Eyefluence was the shortest demo I did at CES, but it was enough to show me the future of using your eyes to control things. The tiny Eyefluence sensors are attached to the inside of an Oculus Rift virtual reality headset and detect the smallest movements in your eyes. I blinked, turned my head, and moved my eyes around, but Eyefluence could still track when and how I wanted to control something. I could navigate through a menu without using my hands, a keyboard, or a mouse. It was fast. It only takes about a minute to learn how to follow Eyefluence’s instructions, after which you can start controlling things that are before your eyeballs. This could very well supply a major ingredient missing from virtual reality headsets and augmented reality glasses.

Vayyar’s 3D sensing

Israeli startup Vayyar uses 3D imaging with radio waves to see through solid surfaces. It can be used to show a 3D model of a cancerous growth in a woman’s breast. It can be used to detect the heartbeat of a person, such as a sleeping baby, in another room. Or it can be used to find studs or pipes that are hidden in a wall. It can see through materials, objects, and liquids. Vayyar can also detect motion and track multiple people in large areas. It works by shooting a radio wave into a solid object and measuring all of the ways that the wave bounces around as it hits various objects. Vayyar collects the reflections and analyzes them, putting them back together as a 3D image in real time. While it is powerful, the amazing technology doesn’t use a lot of power. It comes from seasoned technologists Raviv Melamed, Miri Ratner, and Naftali Chayat, who were inspired by military technology. Melamed, formerly of Intel, told us that the technology is inexpensive. And yes, if you have the ability to see through things, you’re Superman.

ODG’s ultra-wide wide-angle augmented reality glasses

The Osterhout Design Group has taken its technology for night-vision goggles and turned it into augmented reality headsets for government and enterprises. The newest R-7 headset is like looking at a 65-inch TV screen that’s right in front of your eyeballs. The company demoed a future-generation technology with ultra wide-angle viewing. The R-7 has a 30-degree field of view, but the future product has a 50-degree field of view with a 22:9 aspect ratio. It’s more like sitting in the best seat in an IMAX theater, said Nima Shams, vice president at ODG. I was able to look at it and see a wide Martian landscape. The glasses are packed with technology, from Wi-Fi and Bluetooth radios to gyroscopes and altitude sensors. The R-7 costs $2,750, but there’s no telling how much the wide-angle display will be. At some point in the future, I fully expect that his experience is going to be better than going to an IMAX theater.

Cypress’s energy-harvesting solar beacon

Beacons are devices that can connect to your smartphone using a local Bluetooth network. Retailers like to use them to send special offers to your smartphone. That technique can target people walking by a specific store and get them to come inside. But Beacons often run out of battery. By combining technology from Spansion (which Cypress Semiconductor has acquired) and Cypress, the product designers can create a Beacon with a solar energy array. Using that technology, the device can generate its own electricity and doesn’t need a battery. You can embed this kind of technology in any device that is part of the Internet of Things (smart and connected everyday objects). You could put a Beacon in a cemetery and use it to send a story about the life of someone buried there. “We want the Internet of Things, but nobody wants to change 20 billion batteries,” said Eran Sandhaus, vice president at Cypress Semiconductor. Hundreds of potential advertisers are looking at it. We’ll definitely need new sources of power, whether kinetic or otherwise. This is how the Internet of Things is going to become practical, with billions of smart, connected objects that operate on the slimmest amount of power.

Netatmo’s Presence smart outdoor security camera

Presence is a smart outdoor security camera that sends an alert based on an analysis of a scene. If someone is loitering around your house, Netatmo’s Presence will detect that person and send a message to your smartphone. It can detect the movements of your pet, or it can tell you if someone is dropping a delivery at your door. You can train the camera to stay in a particular zone and, using deep learning technology, analyze only certain types of motion. It also comes with a floodlight. Presence doesn’t dump a ton of video on you. You don’t have to take an online storage subscription out. When it identifies significant events, it saves the video so that you can view it, preventing you having to view long, unedited footage. Presence will be available in the third quarter.

LG Rollable Display

Rollable and flexible displays seem like either science fiction or a waste of time. But the LG rollable OLED screen is real. We can roll up the screen like a newspaper, and, in fact, that might be a good use of the technology. LG is showing a prototype now that is as thin as paper and has a resolution of 810 x 1200, or almost 1 million pixels. I’m not sure how we’ll end up using it. But I suspect the roller display will find many usages over time. This makes me feel like technology is becoming as disposable and flexible as a poster. You can go somewhere, put up a rollable screen, and then turn your surroundings into a movie theater or living room.

AtmosFlare 3D drawing

3D drawing is pretty cool. Adrian Amjadi of AtmosFlare showed me how to draw physical images in 3D, using the 3D drawing pen. The system uses ultraviolet light to cure a resin. You can pull on it and deform it any way you wish, essentially making something like the jellyfish in the video here. The resin sticks on porous things, but not on metal. The longer you leave the UV light on, the harder it becomes. The $30 system is on sale at Toys ‘R Us. The company says this will “forever change the way you do art.” I don’t know if it’s going to do that, but it did give me a small moment when I thought, “Wow, that’s cool.”

Medium painting and sculpting in Oculus Rift

Oculus VR came up with its “paint app” in September, but I finally got some hands-on time with it at CES. I was amazed at how easy it was to sculpt objects using two virtual hands (via the Oculus Touch hand controls and Oculus Rift headset). Expressing yourself with sculpting tools isn’t easy. But sculpting in the virtual space gave me a feeling of instant gratification. I started with a blank slate. Then I selected a tool for adding clay with one of my hands. I was able to change the way that the clay shot out of the Oculus Touch wand by rotating my hand. Then I was able to smooth out the edges, spray paint it, replicate it, and delete whole sections of it using my hands in the virtual world. It really makes you feel like you are sculpting something that is real. I can imagine it will be very easy to use a 3D printer to print out the 3D creations you build. You could certainly do something like this in a video game, like Media Molecule’s upcoming Dreams game on the PlayStation 4. But in VR, you feel like you are also inside the thing you are creating. You can turn the image to view it from new angles. This is one of those experiences that could make your head explode with creativity if you’re a 3D artist or sculptor.

Parrot Disco

Parrot has created a unique drone that can fly for 45 minutes on a single charge and reach speeds up to 50 miles per hour. The Parrot Disco is the Swiss company’s latest entry into one of tech’s fastest-growing markets. The Disco is a flying wing that has a motor. It can fly itself or follow instructions you give it via an app. The drone can also take off and land by itself, using its own autopilot. If you use the Parrot Skycontroller, you can get a first-person view on a tablet screen of everything the drone is seeing. You don’t need any training to fly the drone, which has a range of two kilometers, and can navigate its way back to you.

Bullish on Blended Learning Clusters

Michael Horn
CONTRIBUTOR
An increasing number of regions are trying to create concentrated groups of blended-learning schools alongside education technology companies, which may be key to advancing the blended-learning field and increasing its odds of personalizing learning at scale to allow every child to be successful.

There is a theoretical underpinning for being bullish on the value these clusters could lend to the sector. These early attempts at building regional clusters mirror in many ways the clusters that Harvard professor Michael Porter has written about as having a powerful impact on the success of certain industries in certain geographies. Porter defines a cluster as a geographic concentration of interconnected companies and institutions in a particular field.

“Clusters promote both competition and cooperation,” Porter wrote in his classic Harvard Business Review article on the topic, “Clusters and the New Economics of Competition.” He goes on to note that vigorous competition is critical for a cluster to succeed, but that there must be lots of cooperation as well—“much of it vertical, involving companies in related industries and local institutions.”

The benefit of being geographically based, he writes, is that the proximity of the players and the repeated exchanges among them “fosters better coordination and trust.” The strength comes from the knowledge, relationships, and motivation that build up, which are local in nature. Indeed, new suppliers are likely to emerge within a cluster, he writes, because the “concentrated customer base” makes it easier for them to spot new market opportunities or challenges that players need help solving.

From wine and technology in California to the leather fashion industry in Italy and pharmaceuticals in New Jersey and Philadelphia, clusters have endured and been instrumental in advancing sectors even in a world where technology has reduced the importance of geography.

As Clayton Christensen has observed, clusters may be particularly important in more nascent fields—like blended learning—in which the ecosystem is still immature, performance has yet to overshoot its users’ performance demands, and how the different parts of the ecosystem fit together are still not well understood, and thus the ecosystem is highly interdependent, even as proprietary, vertically integrated firms do not—or in the case of education, often cannot—stretch across the entire value network. In this circumstance, having a cluster with organizations so close together competing and working together may be critical.

Perhaps the most promising blended-learning cluster is blossoming somewhat organically in Silicon Valley, where Silicon Schools Fund (where I’m a board member), the Rogers Family Foundation, and Startup Education are helping fund the creation of a critical mass of blended-learning schools and traditional venture capitalists alongside funders like Reach Capital, Owl Ventures, GSV, and Learn Capital and accelerators like ImagineK12 are helping seed an equally critical mass of education technology companies.

The NGLC Regional Funds for Breakthrough Schools, one of the supporters of the Rogers Family Foundation’s efforts in California, has funded similar regional efforts in New Orleans with New Schools for New Orleans; Washington, DC, with CityBridge Foundation; Colorado with the Colorado Education Initiative; Chicago with Leap Innovations; and New England with the New England Secondary School Consortium.

Student Question | Is Social Media Making Us More Narcissistic?

Are social media like Facebook turning us into narcissists? The Times online feature Room for Debate invites knowledgeable outside contributors to discuss questions like this one as well as news events and other timely issues.

Student Opinion – The Learning NetworkStudent Opinion – The Learning Network
Questions about issues in the news for students 13 and older.

Do you spend too much time trying to be attractive and interesting to others? Are you just a little too in love with your own Instagram feed?

An essay addressing those questions was chosen by two of our Student Council members this week. Angie Shen explains why she thinks it’s important:
As the generation who grew up with social media, a reflection on narcissism is of critical importance to teenagers. What are the psychological and ethical implications of constant engagement with or obsession over social media? How does it change our relationship with others and how we see ourselves?

“Narcissism Is Increasing. So You’re Not So Special.” begins:

My teenage son recently informed me that there is an Internet quiz to test oneself for narcissism. His friend had just taken it. “How did it turn out?” I asked. “He says he did great!” my son responded. “He got the maximum score!”

When I was a child, no one outside the mental health profession talked about narcissism; people were more concerned with inadequate self-esteem, which at the time was believed to lurk behind nearly every difficulty. Like so many excesses of the 1970s, the self-love cult spun out of control and is now rampaging through our culture like Godzilla through Tokyo.

A 2010 study in the journal Social Psychological and Personality Science found that the percentage of college students exhibiting narcissistic personality traits, based on their scores on the Narcissistic Personality Inventory, a widely used diagnostic test, has increased by more than half since the early 1980s, to 30 percent. In their book “Narcissism Epidemic,” the psychology professors Jean M. Twenge and W. Keith Campbell show that narcissism has increased as quickly as obesity has since the 1980s. Even our egos are getting fat.

It has even infected our political debate. Donald Trump? “Remarkably narcissistic,” the developmental psychologist Howard Gardner told Vanity Fair magazine. I can’t say whether Mr. Trump is or isn’t a narcissist. But I do dispute the assertion that if he is, it is somehow remarkable.

This is a costly problem. While full-blown narcissists often report high levels of personal satisfaction, they create havoc and misery around them. There is overwhelming evidence linking narcissism with lower honesty and raised aggression. It’s notable for Valentine’s Day that narcissists struggle to stay committed to romantic partners, in no small part because they consider themselves superior.

The full-blown narcissist might reply, “So what?” But narcissism isn’t an either-or characteristic. It’s more of a set of progressive symptoms (like alcoholism) than an identifiable state (like diabetes). Millions of Americans exhibit symptoms, but still have a conscience and a hunger for moral improvement. At the very least, they really don’t want to be terrible people.

Students: Read the entire article, then tell us …

— Do you recognize yourself or your friends or family in any of the descriptions in this article? Are you sometimes too fixated on collecting “likes” and thinking about how others see you?

— What’s the line between “healthy self-love” that “requires being fully alive at this moment, as opposed to being virtually alive while wondering what others think,” and unhealthy narcissism? How can you stay on the healthy side of the line?

— Did you take the test? What did it tell you about yourself?

Henry Xu, another Student Council member who recommended this article, suggests these questions:

— What about Instagram, Facebook, Snapchat and other social media feeds makes them so hard to put down?

— Do you think this writer’s proposal of a “social media fast” is a viable way to combat narcissism?

— For those who aren’t as attached to social media, do challenges from an overinflated sense of self still arise? If so, from where?

— If everyone is becoming more narcissistic, does that make narcissism necessarily a bad thing?

2015’s Best and Worst States for Teachers

Most educators don’t pursue their profession for the money. But that doesn’t justify paying teachers any less than they deserve, considering the profound difference they make in people’s lives. In reality, however, teachers across the U.S. are shortchanged every year — their salaries consistently fail to keep up with inflation — while the law demands they produce better students.

It’s no surprise that the high turnover rate within the field has been likened to a revolving door. According to the National Center for Education Statistics, about a fifth of all newly minted public-school teachers leave their positions before the end of their first year. And nearly half of them never last more than five.

Besides inadequate compensation, other problems persist in the academic environment. Many teachers, especially novices, transfer to other schools or abandon the profession altogether “as the result of feeling overwhelmed, ineffective, and unsupported,” according to ASCD. Without good teachers who are not only paid reasonably but also treated fairly, the quality of American education is bound to suffer.

In order to help ease the process of finding the best teaching opportunities in the U.S. — and draw attention to the states needing improvement — WalletHub compared the 50 states and the District of Columbia across 13 key metrics. Our data set ranges from the median starting salary to the projected number of teachers per student by year 2022. The results of our study, as well as additional insight from experts and a detailed methodology, can be found below.

Main Findings

Readers Respond to Redesigned, and Wordier, SAT

Is it unfair to some students that the redesigned SAT, being rolled out next month, will include longer and harder reading passages and wordier math problems than before? Anemona Hartocollis’s article on the topic drew more than 900 responses from readers.

Some stressed that college admissions tests, by their very nature, should winnow out weaker readers.

“Why would you want to accept students who can’t read and write at a college level regardless of their background?” asked Ed H. of Irvine, Calif. “Instead of complaining about the idea that it is unfair to certain students, why not make sure those students are better prepared? If the poor can’t read as well as the rich, then that’s the problem that needs to be addressed.” His comment was the most recommended by other readers.
Some readers zeroed in on a sentence in the article that noted educators “fear that the revised test will penalize students who have not been exposed to a lot of reading, or who speak a different language at home — like immigrants and the poor.”

Ed Bloom, from Columbia, S.C., wrote: “I’m a reading specialist. I went nuts. Let’s not penalize people who haven’t been exposed to a lot of driving by flunking them on the driving test. Let’s not penalize the pilot of our jet liner by keeping him out of the cockpit just because he hasn’t been exposed to a lot of flying. The correct way of thinking about all of the above is not to think of it as penalizing but, instead, a need to get that person the experience. … There are lots of ways to get children ‘exposed’ to reading.”

Adam from New York wrote: “You could call it ‘penalizing students who have not been exposed to a lot of reading.’ Or you could call it ‘evaluating students’ reading skills.’”

LindaP in Boston countered with a personal story. Her son is dyslexic, and he found the SAT tough. “The comments here make my blood boil,” she wrote. “‘Who wants a kid in college who can’t read proficiently?’ ‘Prepare them better.’ ‘Perhaps these kids aren’t college material.’ Life and learning is not a straight line, and these tests take many different kinds of learners and pigeonhole each and every one of them.” Her son, she noted, is now an M.D., Ph.D. with a specialty in hematology.

A commenter under the handle R-son from Glen Allen, Va., said his stepson, who is better in math than reading, would soon be taking the test. “The new SAT will be hard for him, but he has an advantage over other students — an $800 Kaplan prep course. So it boils down to this — he’ll score better on the SAT than a lower-income student with the same abilities whose family can’t afford to fork out close to 1K to prep for and take this test. So how is this test, in any form, fair?”

A few commenters critiqued the sample of five math SAT questions that accompanied the article. Ninety-three percent of readers answered the first question in the quiz correctly; 57 percent answered the fourth question correctly. Of an algebra problem about a phone repair technician, a reader using the name Kathy, WastingTime in DC wondered, “Who gets a phone fixed these days?”

One reader, who admitted she answered only one of the five problems correctly, pointed to a question about a pear tree. Gabrielle from Los Angeles wrote: “I am a horticultural therapist who designed and built a therapeutic garden. Here’s the answer to figure out which pear tree to buy: use your relationships. Ask your friends what they’ve had success with. Call me crazy but after I left high school, I never took another math class, and it’s never held me back.”

New York Schools Wonder: How White Is Too White?

How white is too white? At the Academy of Arts and Letters, a small K-8 school in Brooklyn founded in 2006 to educate a community of “diverse individuals,” that question is being put to the test.

The school — along with six others in New York City — is part of a new Education Department initiative aimed at maintaining a racial and socioeconomic balance at schools in fast-gentrifying neighborhoods. For the first time the department is allowing a group of principals to set aside a percentage of seats for low-income families, English-language learners or students engaged with the child welfare system as a means of creating greater diversity within their schools.

The continuing segregation of American schools — and the accompanying achievement gap between white, middle-class students and poorer minority children — has become an urgent matter of debate among educators and at all levels of government. Last week, President Obama lent his weight to the issue when he included in his budget a $120 million grant program for school integration aimed at de-concentrating poverty.

In New York, Mayor Bill de Blasio and Carmen Fariña, the schools chancellor, have disappointed school diversity advocates by failing to make integration a priority. The set-asides plan, approved by Ms. Fariña in November, was the first attempt at addressing the issue across multiple schools.

All of the schools involved enroll children by lottery, rather than having a school zone.

In its early years, Arts and Letters was more than 90 percent black and Hispanic, reflecting the Brooklyn neighborhoods around it, including Bedford-Stuyvesant, Clinton Hill and Fort Greene. More than 80 percent of its students qualified for free or reduced lunch.

But the school gained a reputation for its humanities curriculum, its science lab and its focus on the arts. And newcomers changed the demographic mix of its surrounding blocks. In Bedford-Stuyvesant, Clinton Hill and Fort Greene, the white population rose 120 percent from 2000 to 2010 and the black population fell by 30 percent, according to the Center for Urban Research at the Graduate Center of the City University of New York.

Now, Arts and Letters has become one of Brooklyn’s hottest schools. Half of the school’s kindergartners are white; a mere 12 percent qualify for free or reduced lunch. That has its principal, John O’Reilly, worried.

“I love the fact that so many white affluent families would want to send their children to my school,” he said recently, before rushing off to give another tour. “But I know the impact it has on the diversity of my school.”

Mr. O’Reilly is one of a group of principals — including Julie Zuckerman at the four-year-old Castle Bridge School in Washington Heights in Upper Manhattan, where 21 percent of the students are white, and Arthur Mattia, who recently retired from the Children’s School in the Gowanus area of Brooklyn, where the student population is now 59 percent white — who said they had hoped to create schools where no one race or socioeconomic group was dominant.

Instead, their schools are becoming magnets for middle-class families moving into gentrifying neighborhoods who prefer them to their local zoned schools. The principals are concerned that their schools will “tip” over into majority white, middle-class schools.

They hope the new program will help them maintain more balanced populations.

“This is a very important step,” said David Tipson, the executive director of New York Appleseed, which works to create more integration in city schools. “This is the first time that this D.O.E. — under de Blasio — has begun truly addressing the effect gentrification has on our schools.”

In 2014, the Civil Rights Project at the University of California, Los Angeles released a study showing that New York City has one of the most segregated school systems in the nation. That and discomfort among educators and activists about the high number of racially and economically isolated schools in the city has generated intense discussions about integration.

But educators in New York and across the country are not in agreement about what integration should look like. In 2007, a United States Supreme Court ruling declared school sorting by race unconstitutional in two school districts, Seattle and Louisville, Ky.

Around that time, under Mr. de Blasio’s predecessor, Michael R. Bloomberg, the department discontinued a “controlled choice” plan in District 1, in Lower Manhattan, designed to create diversity in schools. Racial set-asides were done away with at the Brooklyn New School in the 1990s, when race-based admissions were coming under fire nationally.

In 2013, the city approved a plan that allowed Public School 133 in fast-gentrifying Gowanus to set aside seats for English-language learners and students who qualify for free or reduced lunch. Those criteria are generally used as proxies for race in trying to achieve integration. Many advocates believed this would lead to more set-aside plans.

That did not happen.

A strong body of research, beginning in the 1960s with the now-famous Coleman Report, suggests that low-income students do better academically when exposed to middle-class ones. Numerous other studies suggest that middle-class students do not see a decrease in achievement when they go to school with poorer students, and may in fact benefit in nonacademic ways.

But how best to integrate remains up for debate.

Richard D. Kahlenberg, a noted voice in the school-integration movement and a senior fellow at the Century Foundation, posits that low-income students do best when they are in schools that are majority middle class.

Mr. O’Reilly, the Arts and Letters principal, has accepted that as a benchmark. He will give priority to students who qualify for free or reduced lunch for 40 percent of his seats.

But Ms. Zuckerman, the Castle Bridge School principal, challenges the notion that her school needs a large percentage of middle-class families to be a successful place of learning. “I’m good with 20 to 25 percent,” she said.

At Castle Bridge, students from households in which a family member is incarcerated get priority for 10 percent of the seats, and low-income students get priority for 60 percent.

The principals say the set-asides are needed, because once a school is viewed as desirable by middle-class families, their networking capabilities and social capital are far more powerful than any outreach the schools can do to attract lower-income families. All it takes, they say, is a few posts on Facebook, some word of mouth at cocktail parties, preschool fund-raisers and neighborhood playgrounds for a school to be inundated with applications from high-earning families. Those can far outnumber the ones coming from lower-income minority families, so even though seats are given out by lottery, the population can quickly shift.

“There is a number of families,” said Sandra Soto, the principal of Brooklyn Arts and Science Elementary School, in Crown Heights, Brooklyn. “I don’t know what that number is exactly. It doesn’t have to be a lot. But then you become the next place.” In 2012, Ms. Soto took over a failing school that had been more than 95 percent black and Latino, renamed it and overhauled the curriculum.

This school year, around 15 percent of the population is white and more than 5 percent is Asian. Last year, it had a Parent Teacher Association president who was white.

Principals at these schools say they know that middle-class families often bring with them higher test scores, making the schools look better on paper. But several added that chasing test scores was not what had drawn them into education.

Sean F. Reardon, a professor at the Stanford Graduate School of Education who specializes in poverty and inequality, said it was a mistake to blame middle-class white parents for wanting the best schools for their children, even if the cumulative effect tipped the racial balance. The answer, he said, needs to be systemic, with the city’s creating scores of schools designed to be diverse in much the same way the Bloomberg administration developed small schools.

“We know it can be done,” Mr. Reardon said.

Administrators at the seven pilot schools say they are all motivated by their belief that classrooms that are racially and economically diverse are good for students, according to recent research, maybe even making them brighter.

Takiesha Robinson, the mother of a third grader and a pre-kindergartner at Ms. Soto’s school, said she appreciated the access her third grader had gotten to white and Asian families since the school reopened. Ms. Robinson, who is black, says her daughter now knows about Hanukkah, understands what a menorah is and knows the difference between being Pakistani and Chinese.

“I can really, really see the difference,” she said.

Still, Ms. Robinson and other parents said they did not want to see the school “turn all white.”

For some white parents at the school, that is understandable.

Emily Cowan, a freelance artist and social worker, said she was willing to even sacrifice her own kindergartner’s slot next year to “preserve that diversity,” though it would mean sending her son to a different school next year.

For others, it is a bitter pill.

The idea of keeping the school diverse “totally jibes with my politics,” said Mark Schwartz, the owner of a liquor store in Prospect-Lefferts Garden, Brooklyn, who also has a kindergartner at the school. “But what if it means we lose out on this opportunity?”
