Audrey Williams June in The Chronicle of Higher Education:
Lori Whisenant knows that one way to improve the writing skills of undergraduates is to make them write more. But as each student in her course in business law and ethics at the University of Houston began to crank out—often awkwardly—nearly 5,000 words a semester, it became clear to her that what would really help them was consistent, detailed feedback.
Her seven teaching assistants, some of whom did not have much experience, couldn't deliver. Their workload was staggering: About 1,000 juniors and seniors enroll in the course each year. “Our graders were great,” she says, “but they were not experts in providing feedback.”
That shortcoming led Ms. Whisenant, director of business law and ethics studies at Houston, to a novel solution last fall. She outsourced assignment grading to a company whose employees are mostly in Asia.
Virtual-TA, a service of a company called EduMetry Inc., took over. The goal of the service is to relieve professors and teaching assistants of a traditional and sometimes tiresome task—and even, the company says, to do it better than TA's can.
