Some states scramble with flawed Common Core tests, but others argue testing is going well

The jagged roll out of Common Core-aligned tests across the nation continues, the rumors of the Common Core Cataclysm have been overstated, argues Alexander Russo at the Columbia Journalism review.

"But so far, at least, much of the medias coverage of this springs Common Core testing roll out has been guilty of overemphasizing the extent of the conflict, speculating dire consequences based on little information and over-relying on anecdotes and activists claims rather than digging for a broader sampling of verified numbers," Russo argues. "The real story that the roll out of these new, more challenging tests is proceeding surprisingly well could be getting lost."

The Deseret News recently took a detailed look at parental opposition to the new high-stakes tests in Florida, including efforts by Orlando parents to opt their kids out of the test, often met with stiff resistance by school administrators.

And Vermont is now putting a pause its Common Core rollout exam because it doesn't want to create an uneven playing field for schools whose curriculum was not already aligned with the new test.

Vermont secretary of Education Rebecca Holcombe told Vermont Public Radio she expected that the U.S. Department of Education allow that state to treat the test as a pilot this year "with no consequences this year. But districts will be able to use the results to improve teaching and learning."

In New York State, the New York Post reported last week that New York school officials this summer quietly altered the results, dropping several questions that proved to have seem to have wrought massive confusion. And these were not trivial changes: the dropped essay question on the 3rd grade test cut six points out of 55 total.

"After the tests were given last April 1-3," the Post reported, "the state decided to eliminate the results of one multiple-choice question on the 7th-grade ELA exam, two on the 3rd-grade ELA exam, and a four-point essay on the third-grade test."

But Alexander Russo's contention is that these are the kind of isolated snafus that affect any large scale operation of this kind, and he gets frustrated with news reporting that suggests otherwise.

"For the most part, the large-scale snafus that have been predicted do not seem to have occurred," Russo writes, "did not take place last year during the trial run process, and should not continue to be reported until they actually take place."
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.
