The study found that students who took all or part of their instruction online performed better, on average, than those taking the same course through face-to-face instruction. Further, those who took "blended" courses -- those that combine elements of online learning and face-to-face instruction -- appeared to do best of all. That finding could be significant as many colleges report that blended instruction is among the fastest-growing types of enrollment.

While the new study provides a strong endorsement of online learning, it also notes findings about the relative success (or lack thereof) of various teaching techniques used in online courses. The use of video or online quizzes -- frequently encouraged for online education -- "does not appear to enhance learning," the report says.

But noting the caveats in the report about factors other than medium of instruction, he said that "we should not take the report as saying it is simply better to move to online learning. These results demonstrate why more research is needed -- broadly based research that moves well beyond case studies conducted by distance education practitioners, research focused on student retention in online environments and especially research that looks behind the instructional medium to isolate the characteristics of instruction that produce positive results. Successful education has always been about engaging students whether it is in an online environment, face to face or in a blended setting. And fundamental to that is having faculty who are fully supported and engaged in that process as well."

Thrun, a German-born and largely self-taught expert in robotics, is famous for leading the team that built Google’s self-driving car. He is offering his “Introduction to Artificial Intelligence” course online and free of charge. His remote students will get the same lectures as students paying $50,000 a year, the same assignments, the same exams and, if they pass, a “statement of accomplishment” (though not Stanford credit). When The Times wrote about this last month, 58,000 students had signed up for the course. After the article, enrollment leapt to 130,000, from across the globe.

Thrun’s ultimate mission is a virtual university in which the best professors broadcast their lectures to tens of thousands of students. Testing, peer interaction and grading would happen online; a cadre of teaching assistants would provide some human supervision; and the price would be within reach of almost anyone. “Literally, we can probably get the same quality of education I teach in class for about 1 to 2 percent of the cost,” Thrun told me.

Thrun believes there are technological answers to all of these questions, some of them being worked out already by other online frontiersmen.
