Mixed bag when US exam scores compared globally

WASHINGTON (AP) — So how do U.S. eighth-graders do in math and science when compared to their peers around the globe? Turns out it matters which state they live in, according to a study being released Thursday.

Massachusetts was the top performing state, but it still lagged behind some Asian countries in terms of its students' overall score on exams and the number of high achievers.

Mississippi, Alabama and the District of Columbia students scored below the international average on both exams, meaning their scores were on par with Kazakhstan and Dubai, United Arab Emirates.

West Virginia, Oklahoma and Tennessee students scored below the international average in math.

Jack Buckley, commissioner of the Education Department's National Center for Education Statistics, which released the study, called the results a "good-news, bad-news scenario" that probably will bolster both those who say the U.S. is doing fine in global competitiveness as well as those on the other side.

Overall, a majority of states performed above the international average in both subjects.

"Our states really are scattered across the performance levels," Buckley said in a conference call with reporters.

Education Secretary Arne Duncan said in a statement that the study provides "powerful confirmation that demography need not be destiny when it comes to school performance — state policies matter too."

The study compared every state, the District of Columbia and Defense Department schools against 38 countries and nine additional subnational education systems. Some countries, including China, India, France and Germany, did not participate.

Researchers took eighth-grade test results in math and science from the 2011 National Assessment of Educational Progress (NAEP) to predict performance on the international comparative study test known as the Trends in International Mathematics and Science Study (TIMSS). Nine states participated directly in TIMSS.

NAEP includes the scores of students tested with accommodations; TIMSS does not. Buckley said statistical modeling was used to account for that difference.

South Korea, Singapore, Taiwan, Hong Kong and Japan were the top scorers in math followed by Massachusetts, Vermont, Minnesota, New Jersey and New Hampshire.

In science, Massachusetts was behind the top scorer, Singapore. Taiwan was next, followed by Vermont. The top 10 also included South Korea and Japan — and New Hampshire, North Dakota, Maine and Minnesota.

Mark Schneider, vice president at the American Institutes for Research and a former commissioner for the National Center for Education Statistics, said one of the most disturbing results from the study is the low numbers of "advanced" achievers in the United States compared with other countries.

Even in high-scoring Massachusetts, where 19 percent of students reached the "advanced benchmark" in math and 24 reached it in science, there were fewer higher achievers than in some other countries. About half the students in Taiwan, South Korea and Singapore reached the high benchmark in math and 40 percent of students in Singapore did so.

On the other end, for example, Alabama had a lower percent of "advanced" achievers in math than Romania and Turkey — two countries it overall scored higher than.

"In a world in which we need the best, it's pretty clear many states are empty on the best," Schneider said.

Tom Loveless, a senior fellow at the Brookings Institution, said one thing that's hidden in the results of this study is that even in high-achieving states, there are low performers who need to be brought up from the bottom.

"If we as Americans want to get all of our kids achieving at the highest level, in terms of worldwide academic achievement, we have a lot of work and it's not just the low scoring states where it's obvious," Loveless said.

The scores were ranked on a scale of 1,000.

In math, the average state scores ranged from 561 for Massachusetts to 466 for Alabama.

In science, the average state scores ranged from 567 for Massachusetts to 453 for the District of Columbia.

Hortonworks makes Hadoop more versatile in new distro


Built on Apache Hadoop YARN architecture, HDP 2.0 changes Hadoop from a single-purpose Web-scale batch data processing platform into a multi-use operating system for batch, interactive, online, and stream processing.


Case in point: Running SQL on Hadoop. Business analysts have been using SQL as the query language to perform ad-hoc queries against data warehouses for years. If you're creating a data lake using Hadoop, you've got to be able to query that data using SQL.


[ Harness the power of Hadoop with InfoWorld's 7 top tools for taming big data. | Explore the current trends and solutions in BI with InfoWorld's interactive Business Intelligence iGuide. | Discover what's new in business applications with InfoWorld's Technology: Applications newsletter. ]


"But by building SQL access on top of Hadoop, it just highlights the challenge of Hadoop being a single application system," writes Arun Murthy, founder and architect at Hortonworks and former architect of the Yahoo Hadoop Map-Reduce Development Team. "For when I run a SQL query on that data, it could consume all the resources of the cluster and cause performance issues for the other applications and jobs running in the cluster-not a good outcome to say the least."


The answer to that problem is YARN (Yet Another Resource Negotiator), the foundation of the recently released Hadoop 2. Apache Hadoop YARN serves as the Hadoop operating system, taking what was a single-use data platform for batch processing and evolving it into a multi-use platform that enables batch, interactive, online and stream processing.


YARN acts as the primary resource manager and mediator of access to data stored in HDFS (Hadoop distributed file system), giving enterprises the capability to store data in a single place and then interact with it in multiple ways, simultaneously, with consistent levels of service.


Hortonworks, provider of the HDP (Hortonworks Data Platform), one of the most popular distributions of Hadoop, was quick to take up the YARN banner today with the announcement of the general availability of HDP 2.0.


HDP 2.0 is the first commercial distribution built on Hadoop 2, delivering the YARN-based architecture and new features from Phase 2 of the Stinger Initiative. The Stinger Initiative is a community-based effort that aims to enhance the speed, scale and breadth of SQL semantics supported by Apache Hive.


"The YARN-based architecture of HDP 2.0 delivers on our mission to enable the modern data architecture by providing one enterprise Hadoop that deploy integrates with existing, and future, data center technologies, says Shaun Connolly, vice president of corporate strategy at Hortonworks.


"In our benchmarking across some of the customers we've been working with, classic MapReduce jobs will just port over from the 1.0 line to the 2.0 line," Connolly adds. "You get twice the performance and you can run twice the jobs. You get a lot more headroom in the cluster."


Meanwhile, the addition of Hive 0.12 (the culmination of phase 2 of the Stinger Initiative) delivers large performance gains for queries that bring them in line with "human interactive response time rather than batch response time."


Connolly says queries that previously took 1,400 seconds for a response can now get responses in fewer than 10 seconds. Phase 3 (targeted for the first quarter of 2014), is expected to improve those response times even more by allowing interim processing to happen within memory.


HDP 2.0 is available for download now. Connolly says HDP 2.0 for Windows will be available next month.

"Bratty" Katy Perry Had A Lot of Growing Up to Do

It's okay, you don't have to fight it: We all have crushes on Katy Perry. Not only is the "Roar" singer gorgeous, funny and talented, but she seems like she's having more fun than Rihanna, Lady Gaga and Taylor Swift put together. With her latest album, Prism, out now, she seems like she's doing fame right. And maybe, as she reveals in the new issue of W, it's because she started out doing it wrong.

Kristin Chenoweth Nearly Vomits on The Tonight Show for $3,000 During Eating Contest


Charitable Kristin Chenoweth! The pint-sized singer and actress visited Jay Leno on The Tonight Show Tuesday, Oct. 22, and was challenged to another round of an eating contest -- and very nearly threw up.


As part of an ongoing bet with the late night host, Chenoweth, a very picky eater, must eat something weird in order to win money for the charity of her choice. (She previously ate sea urchin for $500, but refused to eat her own poop for $1,000.)

On Tuesday, the 45-year-old star decided that any money she won would go to a charity supporting breast cancer in honor of breast cancer awareness month. "You know that I'm sick," she warned Leno, explaining she was suffering from vertigo.


Watch a video of Kristin Chenoweth eat blood pudding and haggis -- and nearly vomit -- on The Tonight Show to win $3,000 for charity during an eating contest.

Still, Leno didn't go easy on her. The host offered her the choice of taking a bite of either blood pudding or haggis. "Now this is blood pudding," he said pointing to the dish. "That's pork, beef, blood and oats. You like oats. And this is haggis, which is animal fat, lamb's liver and beef."

Leno offered to pay Chenoweth $1,500, but agreed to double it if she took a bite of both. Not willing to lose money for her charity, Chenoweth bravely took a bite of each -- but it didn't go down easy. The Good Wife actress nearly puked -- twice -- on Leno's set!

Soft-spoken teen accused of killing Mass. teacher


DANVERS, Mass. (AP) — A 14-year-old Massachusetts high school student charged with killing a teacher has been ordered held without bail.

Philip Chism was ordered held Wednesday at his arraignment in adult court on a murder charge in Salem.

His defense attorney, Denise Regan, argued for the proceedings to be closed and her client to be allowed to stay hidden because of his age. The judge denied the request. Regan declined to comment outside court.

Prosecutors say the teen beat well-liked Danvers High School math teacher Colleen Ritzer to death. Her body was found in the woods behind the school early Wednesday.

The boy also was reported missing Tuesday. He was spotted walking along a road early Wednesday.

He is due back in court Nov. 22.
