Who Needs Teachers When You've Got Robots to Grade Essays?

Britain to Start Marking English Exams with Robots
Automated test scoring is nothing new. Most of us are quite familiar with the act of filling in little #2 pencil marks on a Scantron, and having it fed through a machine that puts a depressing little red dash next to each wrong answer. That's all well and good for tests with simple multiple choice answers, but what about tests with written answers and essay questions, like an English test? Well, Pearson, an America-based education company, will be debuting a new English proficiency exam given to students seeking admission to British universities.

The Times Educational Supplement (TES) reported that Pearson had developed an artificial intelligence program that can assess the use of grammar and vocabulary in essays. A representative from Pearson told TES that the system was just as accurate as a human marker, but removed variables like fatigue and changes in mood. The program was created by analyzing how human scorers marked tests, but academics, teachers, and common sense says that a machine will never be able to pick up on the small quirks that make for quality writing.

Southwest Details In-flight Wi-Fi Plans, Yahoo! Partnership


Southwest got official with its Wi-Fi plans late last month, but avid travelers who favor the only airline worth flying anymore (okay, Virgin America and JetBlue aren't bad either) were left wondering about most of the details. Today, the company has fired up a single Row 44-equipped flight, and it has announced plans to equip three more airplanes with in-flight WiFi by early next month. Furthermore, it has nailed down a partnership with Yahoo! in order to offer an in-flight homepage with "destination-relevant content." The service, which has yet to receive final FCC approval, will be tested over the next few months, and if all goes well, we're left to hope, pray and beg that the airline rolls it out fleet-wide. There's no mention of an actual price here, but it would totally rule if it bucked the trend and provided it to everyone for free. Right, everyone? [Via Gadling]

Boeing's Hydrogen-Powered Airplane Completes Test Flights

BoeingBoeing's European outpost has achieved a technical feat that, while not expected to revolutionize air travel, at least shows progress in the effort to lower the overall reliance on very pricey (and, you know, scarce) jet fuel.

Boeing Research & Technology Europe, which operates out of Madrid, has been working on the "Fuel Cell Demonstrator Airplane" since 2001. The goal has been to "demonstrate for the first time that a manned airplane can maintain a straight level flight with fuel cells as the only power source."

What does this mean on a practical level for regular folks like us? Not a whole heck of a lot, with most applications likely being for extending the fly time of unmanned aircraft -- although the technology could be applied to regular jets to help power the electrical systems.

Of course, like many scientific endeavors, the ultimate practical use may not yet be realized by the engineers involved. (Wasn't the active ingredient in Viagra originally intended to help people with hypertension? Researchers, of course, quickly realized an interesting side effect there. The same could always happen with fuel cells, no?)

Boeing sent a the piloted, fuel cell-powered aircraft into the air three times during February and March. The two-seat Diamond Aircraft Dimona motor-glider, with a 16.3m (53.5ft) wingspan, was modified with a proton exchange membrane fuel cell, lithium-ion battery hybrid system. Launched from Ocaña air field, near Madrid, Spain, the plane flew straight and level at 3,300 feet on fuel cell power alone for 20 minutes at 60 miles per hour.

Southwest Airlines Adding In-Flight WiFi Internet Access This Summer


One of the United States' best-known, no-frills airlines may be getting a bit, well, frilly, as Southwest has just announced it will be testing a new broadband, satellite-delivered Internet access service to its passengers starting this summer.

Dallas, Texas-based Southwest is working with Row 44 (self-described world leader in airborne broadband communication) to equip four aircraft for trials this summer so customers can have access to e-mail, music, shopping, and virtual private networks (VPN) via a high-speed connection.

Row 44 is the same company working with Alaska Airlines to implement its in-air wireless access tests this Spring.

Virgin America is also promising in-air internet access, although the timetable for that service has not yet been set. American Airlines and JetBlue have also announced plans for in-flight Internet access, although JetBlue's plans may be limited to a few types of devices and services. American is working with AirCell, a competitor to Row 44. No exact timetable is available for their full service roll-outs, either.

The Trippiest Optical Illusions on the 'Net

Instant Test: Are You Creative or Logical?

This silhouette wins the award for coolest thing we've seen all day -- and it's not just because the tiny dancer above is in the buff. This is a little test that will tell you whether the left or right hemisphere of your brain is more dominant.

Instead of concentrating on her chest, concentrate on the woman's movement. If you see her spinning clockwise, that means you're using the right side, or more creative side of your brain. If she appears to be moving counter-clockwise, then that means the left side, or more logical side of your think muscle is superior.

At the Switched office, some of us see her going clockwise, others see her spinning counter-clockwise. At least one of us claims to see both, while another one of us opened this animation in Adobe ImageReady in order to isolate the frames to see if there's any direction-changing funny business going on. There isn't.

Take the test for yourself. Then, if you have time for a 50-question survey, compare these instant results to a more thorough diagnosis.

But wait! We have more optical illusions for you!
