Facebook enters the education platform wars, partners with Silicon Valley charter network

A charter school network that operates 11 schools in California and Washington state announced that it is partnering with Facebook to develop an innovative personalized learning software platform that is about to begin its second year of testing, the New York Times reports.

The software program, known as Summit Basecamp, puts students in charge of their own progress, allowing them to organize and schedule pieces of what they need to learn themselves, while teachers work directly with students one on one. The idea is to give students greater control, helping them learn to be "project managers" for their own lives, not just in school.

Facebook's announcement that it had come on board to help improve and scale the software is a huge boost for Summit Public Schools, but it paved the way for that partnership by developing and testing the software itself over the past school year.

Summit began the experiment last year with 19 schools scattered across 13 states. Fifteen of those schools were traditional public schools, and only four were public charters, proof that Summit does not view this platform as a proprietary, niche product or one aimed purely at charters.

Lizzie Choi, Summits Basecamp director, told EdSurge.com that opening up the project to a wide variety of schools for testing was important from the outset. The team wanted to see what it looks like to use the PLP tool in a variety of contexts" and they wanted to break out of the silo effect by engaging schools across the country in testing and development.

"The software gives students a full view of their academic responsibilities for the year in each class and breaks them down into customizable lesson modules they can tackle at their own pace," according to the New York Times article. "A student working on a science assignment, for example, may choose to create a project using video, text or audio files. Students may also work asynchronously, tackling different sections of the years work at the same time."

Recognizing that transitions take time and a steep learning curve was likely, Summit Basecamp noted in a progress report released this spring that it expected that student achievement would "hold steady" during the transition. Instead, the mid-year assessment showed above average progress in math and reading.

Reading progress for all students improved 38 percent better over the national average, while math held steady. But for students who entered the year furthest behind, math improved 23 percent over similar peers nationally, while reading gains were a startling 93 percent better.

"The system inverts the traditional teacher-led classroom hierarchy," The New York Times notes, "requiring schools to provide intensive one-on-one mentoring and coaching to help each student adapt."
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.
