Keeping an Eye on Online Test-Takers



Millions of students worldwide have signed up in the last year for online courses. But when those students take the final exam in calculus or genetics, how will their professors know that the test-takers on their distant laptops are doing their own work, and not asking Mr. Google for help? The issue of online cheating concerns many educators.

Technology plays a big role in solving this problem. Squads of eagle-eyed humans at computers can monitor faraway students via webcams, screen sharing and high-speed Internet connections. The developing technology for remote proctoring may end up being as good — or even better — than the live proctoring at bricks-and-mortar universities. Having a camera watch you doesn’t seem any worse than an instructor at the front constantly looking at you, and it may even be more efficient.
Other remote proctoring services offer different solutions. At Software Secure in Newton, Mass., test-takers are recorded by camera and then, later, three proctors independently watch a faster-speed video of each student. Compared with services where proctors are monitoring students in real time, this combination of recording first and viewing later gives greater latitude for the institution to adjust the timing of exams to whenever they want.
Employees say they are well versed in the sometimes-ingenious tactics used to dodge testing rules. “We’ve seen it all,” said Matt Jaeh, vice president for operations. “After you’ve sat there a while watching people, the patterns of behavior for normal people versus the people trying to sneak in a cellphone to look up information are very clear.”
Beyond the issue of proctoring, online courses are also addressing the problem of making sure that credit-seeking test-takers are the same students who enrolled in the course. Some companies now offer the service that confirms students’ identity by matching webcam photographs as well as pictures of acceptable photo IDs. Students also type a short phrase, which is analyzed by a software program. It takes note of the typing rhythm and other characteristics, like how long the keys are pressed down. Then, when a student submits homework or takes a test, the algorithm compares a bit of new typing with the original sample.
       What do you think about the services? Do you think schools should use those technologies for monitoring their online courses’ students? Do you think that’s ethical?
