How one program helps students by keeping teachers in the classroom

Research shows that quality teachers have more impact on student achievement than any other variable, but until now there has been no real career path for a great teacher to follow that doesn't take them out of the classroom.

"When it comes to student performance on reading and math tests," concluded the RAND corporation in a 2012 study, "a teacher is estimated to have two to three times the impact of any other school factor, including services, facilities, and even leadership."

It's a paradox that an educational consulting group in North Carolina is offering a program it calls "opportunity culture," which allows exceptional teachers to become multi-classroom mentors and coaches to less experienced teachers in their school, with corresponding increases in their pay and a broadening of their impact.

Charlotte, North Carolina, is testing this approach on a large scale, the Charlotte Observer notes, with opportunity teachers now in 17 schools, where the mentoring super teachers can earn up to $23,000 more per year.

"The program started in Charlotte as part of Project LIFT, the $55 million program to aid struggling west Charlotte schools," the Observer reports. "LIFT will soon post job openings for 20 more opportunity culture teachers this year, bringing their total to 55."

NPR did a segment on Whitney Bradley, an "opportunity culture" teacher at one of the Charlotte schools participating in the program this year.

"How do we create career paths for teachers, fabulous classroom teachers like Whitney Bradley, so we don't have to make them administrators?" professor Barbara Stengel of Vanderbilt University's Peabody College asked NPR. "They can still be in classrooms."

"The new hierarchy solves several problems at once," NPR reports. "The lead teacher becomes an automatic mentor to the teachers she oversees. The mid-level management position also helps the school justify paying them more while giving teachers something to aspire to that won't take them out of the classroom."
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
