EAST LANSING, Mich. Students perform better when their instructors use hand gestures a simple teaching tool that could yield benefits in higher-level math such as algebra.

A study published in Child Development, the top-ranked educational psychology journal, provides some of the strongest evidence yet that gesturing may have a unique effect on learning. Teachers in the United States tend to use gestures less than teachers in other countries.

"Gesturing can be a very beneficial tool that is completely free and easily employed in classrooms," said Kimberly Fenn, study co-author and assistant professor of psychology at Michigan State University. "And I think it can have long-lasting effects."

Fenn and Ryan Duffy of MSU and Susan Cook of the University of Iowa conducted an experiment with 184 second-, third- and fourth-graders in Michigan elementary classrooms.

Half of the students were shown videos of an instructor teaching math problems using only speech. The others were shown videos of the instructor teaching the same problems using both speech and gestures.

The problem involved mathematical equivalence (i.e., 4+5+7=__+7), which is known to be critical to later algebraic learning. In the speech-only videos, the instructor simply explains the problem. In the other videos, the instructor uses two hand gestures while speaking, using different hands to refer to the two sides of the equation.

Students who learned from the gesture videos performed better on a test given immediately afterward than those who learned from the speech-only video.

Another test was given 24 hours later, and the gesture students actually showed improvement in their performance while the speech-only students did not.

While previous research has shown the benefits of gestures in a one-on-one tutoring-style environment, the new study is the first to test the role of gestures in equivalence learning in a regular classroom.

The study also is the first to show that gestures can help students transfer learning to new contexts such as transferring the knowledge learned in an addition-based equation to a multiplication-based equation.

Fenn noted that U.S. students lag behind those in many other Western countries in math and have a particularly hard time mastering equivalence problems in early grades.

"So if we can help them grasp this foundational knowledge earlier," she said, "it will help them as they learn algebra and higher levels of mathematics."

88% Beyond The Hills

All Critics (64) | Top Critics (24) | Fresh (56) | Rotten (8)

The film offers rewards for the patient viewer as it examines conflicting visions of love played out in a remote faith-based community.

An austere but subtly textured retelling of a 2005 news story in which a young woman died during an exorcism.

Fascinating [and] anguishing ...

Cristian Mungiu's "Beyond the Hills" moves so effortlessly through the gnarly intersection of love, loss, God and godlessness that you barely notice how much he's doing, and with such effortless grace.

Of all the movies culminating in a rite of exorcism, Romanian writer-director Cristian Mungiu's remarkable "Beyond the Hills" stands alone.

One of the year's most powerful films.

Such is the rigorous and high-minded nature of Romanian cinema that even a real-life exorcism story can inspire something loftier than a horror movie.

Heartbreak at a Romanian convent

...Cristian Mungiu has taken a real life event...to consider deeply human philosophies such as freedom vs. discipline, love vs. security, the choices facing those without financial recourse and the hypocrisies of organized religions.

I found it riveting to watch and fascinating to think about afterwards.

An undeniably tough watch.

Stark, deadpan, and darkly dry.

With this viscerally involving drama, acclaimed Romanian filmmaker Mungiu (4 Months, 3 Weeks and 2 Days) tells another strikingly original story of women caught between old and new world beliefs.

Mungiu is not preaching - he is telling us what can happen when people are trapped within their own emotions and circumstances. Remarkable.

Mungiu's human comedy leaves off where it begins (spoiler alert): out in the middle of nowhere, no direction home.

...if Beyond the Hills is an exorcism movie, the scariest thing about it is that there isn't a demon to be found.

The film's final shot goes straight to the story's heart and the spectator's. Amazing grace. Now at last we know what those words mean.

...quiet, but also quietly devastating, with detours down the roads of intolerance, mercilessness, cold rejection of outsiders' experiences, mystical and subjective interpretation of "signs," overt woman-on-woman misogyny and brutally strict penance...

A slowly, quietly riveting passion play for a nation grappling with secularism and modernity.

Ashley Judd 'unable' to run for Senate

The actress won't attempt to take Senator Mitch McConnell's seat representing Kentucky in the U.S. Senate, according to a tweet published on Wednesday and confirmed by her publicist. McConnell's seat is one of 14 Republicans are defending in 2014.

Actress Ashley?Judd?announced Wednesday she won't run for U.S. Senate in Kentucky against Republican Leader Mitch McConnell, saying she had given serious thought to a campaign but decided her responsibilities and energy need to be focused on her family.

The former Kentucky resident tweeted her decision.

"Regretfully, I am currently unable to consider a campaign for the Senate. I have spoken to so many Kentuckians over these last few months who expressed their desire for a fighter for the people & new leader," Judd?wrote.

"While that won't be me at this time, I will continue to work as hard as I can to ensure the needs of Kentucky families are met by returning this Senate seat to whom it rightfully belongs: the people & their needs, dreams, and great potential. Thanks for even considering me as that person & know how much I love our Commonwealth. Thank you!"

Her publicist Cara Tripicchio confirmed?Judd's?decision.

The 44-year-old?Judd?had hinted last week that she was nearing a decision about the race.

Now living in suburban Nashville, Tenn.,?Judd?has said little publicly about her intentions. However, she has been meeting with several Democratic leaders, including Gov. Steve Beshear, to discuss a possible run.

Defeating McConnell would be the Democrats' biggest prize of the 2014 election. His seat is one of 14 that Republicans are defending while Democrats try to hold onto 21, hoping to retain or add to their 55-45 edge.

The star of such films as "Double Jeopardy" and "Kiss the Girls" is known for her liberal political views and she would have been running in a largely conservative state where Republicans hold both Senate seats and five of the six seats in the U.S. House.

Former State Treasurer Jonathan Miller, a?Judd?supporter, said she would have been a strong candidate.

"As a Kentuckian and someone who was really enthusiastic about her as a candidate, this wasn't the news I was hoping for," Miller said. "But as her friend, from the first time we talked about the race last summer, I was very candid about the grueling nature of politics. It's become a very unpleasant business and running against Mitch McConnell would be an extraordinarily difficult and grueling experience."

McConnell, who spent some $20 million on his last election and who has already raised $10 million for the next one, had already been taunting would-be Democratic challengers in a comical online video intended to raise second thoughts about taking on a politician known as brawler. The video plays on the fact that?Judd?lives in Tennessee.

Republican-leaning group American Crossroads in its own online video also plays on the Tennessee angle and ties her closely to President Barack Obama, who is unpopular in Kentucky.

University of Louisville political scientist Laurie Rhodebeck said?Judd?certainly wasn't frightened out of the race.

"She doesn't strike me as a shrinking violet," Rhodebeck said. "I think the real issue would be how much disruption she wanted in her life. This was the kind of thing that she would have to throw herself into 100 percent in order to make it worthwhile."

Judd?and three-time Indianapolis 500 winner Dario Franchitti separated early this year after marrying in his native Scotland in 2001.

Judd's?decision not to enter the race leaves the Democratic Party in search of a candidate. Many of Kentucky's top Democrats, including Beshear, have said they won't run. However, a rising star within the party, Secretary of State Alison Lundergan Grimes, hasn't ruled the race out. Grimes declined comment Wednesday evening through her spokeswoman, Lynn Sowards Zellen.

Associated Press writer Janet Cappiello contributed to this report.

MakerBot teaming up with OUYA to make 3D printed consoles

Makerbot Ouya consoles

Just as the first systems are getting ready to ship this week, MakerBot has teamed up with OUYA to make 3D printable cases for the consoles.

The partnership means that anyone who gets their hands on an OUYA and happens to have a MakerBot Replicator 2 can design and print custom cases for their console. OUYA helped create 3D printing design kits, which are available on MakerBot's website Thingiverse.com for anyone to use. OUYA sees the hardware customization as an extension of their commitment to having an open console.

If you're willing to spend the time (and money) on a 3D printer, there's no reason in their eyes that you shouldn't have a custom case around your OUYA. MakerBot plans to show off the first 3D printed OUYA consoles at the launch event tomorrow in San Francisco, so be on the lookout for some crazy new designs.
