Finding ways to thwart the ingenuity of computer-savvy students is crucial to proving Internet courses and diplomas are valid. Webcams and keystroke monitoring are among tools in use.

While Jennifer Clay was at home taking an online exam for her business law class, a proctor a few hundred miles away was watching her every move.

Using a webcam mounted in Clay’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes shifted from the computer screen and listened for the telltale sounds of a possible helper in the room.

Her computer browser was locked — remotely — to prevent Internet searches, and her typing pattern was analyzed to make sure she was who she said she was: Did she enter her password with the same rhythm as she had in the past? Or was she slowing down?

In the battle against cheating, this is the cutting edge — and a key to bolstering integrity in the booming field of online education.

Only with solid safeguards against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven’t just Googled their way to an “A+” or gotten the right answers texted to their smartphones.

“I think it gives credibility to the entire system, to the institution and to online education in general,” said Clay, 31, who is studying accounting at Western Governors University, a nonprofit institution that enrolls many working adults like her.

But defeating the ingenuity of computer-savvy students is a huge challenge that has attracted much investment and attention in the last year. The whole system can be corrupted with something as low-tech as a cheat sheet tucked out of camera sight.

“Online courses are under scrutiny to show evidence of integrity in ways that face-to-face courses aren’t,” said Teddi Fishman, director of the International Center for Academic Integrity at Clemson University in South Carolina.

William Dornan, chief executive of Phoenix-based Kryterion Inc., which monitors tests for several schools and companies, said technology is up to the task. He contends that his webcam system reduces cheating far below its occurrence in regular lecture halls.

“Security is incredibly important,” he said. “If it’s known you can cheat, that completely dilutes the brand.”

Some students say no security measures are fail-safe.

UC Santa Cruz sophomore John Shokohi took a water issues class last spring that allowed webcam proctoring in his dorm. The 19-year-old environmental studies major said he did not know of specific cheating, but added that online education was a tempting target for desperate students.

“Because you are not around other students, you are not so worried about people watching you or getting caught,” he said.

Although online classes have existed for more than a decade, the debate over cheating has become sharper in the last year with the emergence of “massive open online courses.”

Those MOOCs, as they are known, usually are offered free by such organizations as Coursera and edX in collaboration with colleges, and can enroll thousands of students in one class.

Private colleges, public universities and corporations are jumping into the online education field, investing millions of dollars to tap into the vast pool of potential students, while also taking steps to help ensure honesty at a distance.

Despite public suspicion about online deception, studies seem to show that there is not much difference in the amount of cheating that occurs in virtual and real classrooms. A 2010 study in the Online Journal of Distance Learning Administration found that 32.7% of online students self-reported cheating at least once on tests, compared to 32.1% of those in on-campus classes.

But as online education grows, even small vulnerabilities could become big problems, academics fear.

The “size and scale [of MOOC courses] make it a bigger issue,” said Cathy Sandeen, vice president for education attainment and innovation at the American Council on Education.
