Weak geography competence among U.S. eighth-graders flows from narrowed focus, experts argue

Most eighth-graders are not proficient in geography, a new report by the U.S. Government Accounting Office finds, with just 24 percent of eighth-graders proficient in geography in the 2014 National Assessment of Educational Progress scores.

NAEP testing is a statistical sample only at selected school, and no one school is judged by the results, which means schools are not motivated to teach to the NAEP test. NAEP is widely seen as the gold standard of U.S. educational assessment.

Geography is measured every year. It was measured in 2014 and in 2010, but prior to that the last test was in 2001, and then it reaches back all the way to 1994. Since 1994, things have not changed all that much. The same 24 percent of eighth-graders were proficient in geography then as 20 years later in 2014.

The GAO report found several explanations for the lack of progress, including misconceptions about what geography is, lack of teacher training, poor instructional materials and lack of geographic technology in the classroom.

Narrowed focus

Geography is being shortchanged by a narrow focus on reading and writing, argues Thomas Herman, a geography professor at San Diego State University and a coordinator for the California Geographic Alliance, part of a network of state alliances started in 1986 with the support of National Geographic.

The networks mission is to help improve geography education in classroom by offering teachers training and curriculum tools to integrate geography. The network also helps nudge policymakers, administrators and teachers to broaden the curriculum, Herman said.

In Hermans view, the heavy emphasis on standardized testing of reading and math is driving out the content-oriented learning that, ironically, provides the purpose and motivation for those basic skills.

This emphasis actually flies in the face of the new Common Core curriculum, which strongly emphasizes critical thinking, Herman notes. "I see a misalignment between what is being tested and the accountability feedback loop," he said, which results in overemphasis on ultra-fundamentals.

"If testing only measures reading and math," he adds, "it doesn't matter what the guidance says about integrated, inquiry-driven learning. The superintendent will only be focused on making the test scores look better.

"Geography offers relevance," Herman said. "We live in a geographically constructed world. Our roles are constructed around geography. Kids are interested in what's going on out there."

Advancing technology

Geography is not about memorizing state capitals," said Rebecca Theobald, a geography professor at the University of Colorado, Colorado Springs, and the coordinator of the Colorado Geographic Alliance.

Ideally, Theobald said, as students get older and gain more content knowledge, they can become knowledge producers, using rapidly advancing geospatial technology, the more rudimentary forms of which are now found on most smartphones.

"Geography is an integrative discipline," Theobald said, "and can be used to shed light on all kinds of social and scientific issues, from politics and economics to hydrology or morphology."

Some students have mapped rat sightings in New York City, while students in the Northwest have mapped pine beetle infestations, Theobald said. Google Earth also offers possibilities. One analysis of the Darfur tragedy, Theobald noted, outlines a map of Sudan with villages that had been burned in the genocide.

At the early grades, Robert Pondiscio, a senior fellow at the Washington, D.C.-based Fordham Institute, said geography is simply about land forms and earth science being able to identify continents, rivers and lakes, or understand the difference between desert and tundra.

"A literate person knows what Tundra means, Pondiscio said, and when they encounter it in reading, it doesnt slow them down.

These concepts build on each other, he continues. A history text may state that annual flooding in the Nile delta made Egypt a fertile agricultural superpower. But without some knowledge of geography, that phrase might make little sense to young readers, Pondiscio says.

Content is king

Preoccupation with reading and math scores is self-defeating when those skills are divorced from the content that gives them form and purpose, Pondiscio said.

"Decoding language is a skill," he said, "but reading comprehension is not. Reading comprehension requires shared background knowledge between reader and writer."

After students master basic skills in the early grades, the teachers job is to provide content knowledge, and with it the basic skills needed to expand, Pondiscio said.

After basic decoding is mastered, Pondiscio said, "any effort to treat reading as a skill makes things worse, not better. If you are not learning geography, you are not learning to read."

Pondiscio agrees with Herman that, properly understood and implemented, the much-vilified Common Core curriculum is an antidote to the preoccupation with testing. "If I could have one wish," he said, "Its that every elementary teacher would understand that teaching reading is teaching content."
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.
