Bringing Facial Recognition Software Into The Classroom

A recent study showed how using the software to identify struggling students could help teachers stay attuned to their needs, whether they're in the room with them or at a remote location many miles away.

What's the Latest Development?

By recording students' faces while they were using a computer coding tutorial, researchers at North Carolina State University were able to determine, with the help of facial recognition software, which ones were having trouble with the material, as well as which ones found it too easy. They analyzed 60 hours of footage with the Computer Expression Recognition Toolbox -- a software package developed at the University of California-San Diego -- and then compared the analysis with students' stated feelings about the material. The results showed close matches between the two. The team will present their research later this week at the Sixth International Conference on Educational Data Mining.

What's the Big Idea?

The study is one of the latest contributions to the growing research field of affective computing, which involves technology that can recognize and respond to a wide range of human emotions. When it comes to education, such systems can be useful inside of an actual classroom -- where a teacher may not always pick up on every student's ease or struggle with the material -- as well as with massively open online courses (MOOCs) involving thousands of students from all over the world.

Surprising Science

While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.

Why we're so self-critical of ourselves after meeting someone new

A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.

Surprising Science

We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.

NASA launches ICESat-2 into orbit to track ice changes in Antarctica and Greenland

Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.

Firing three pairs of laser beams 10,000 times per second, the ICESat-2 satellite will measure how long it takes for faint reflections to bounce back from ground and sea ice, allowing scientists to measure the thickness, elevation and extent of global ice

Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
