edX Study: Online Course Comparable to On-Campus Counterpart

A free virtual classroom may be just as conducive to learning as a traditional university setting, according to a study of a massive open online course offered by edX.

The report, entitled “Learning in an Introductory Physics MOOC: All Cohorts Learn Equally, Including an On-Campus Class,” found that the “learning gain” of a group of MOOC students was comparable to that achieved by students enrolled in the same course at MIT.

The study also discovered that MOOC students with a variety of academic backgrounds demonstrated roughly the same level of relative improvement over the duration of the course. According to the researchers, these findings reflect positively on the potential of MOOCs to distribute knowledge without a teacher being physically present.

“I want to use MOOCs as an online laboratory to develop a new educational pedagogy,” said David Pritchard, a physics professor at MIT and the principal investigator of the study. “A MOOC is a rising tide that lifts all students.”

Pritchard likens MOOCs to particle accelerators, as both allow for large-scale and instantaneous data collection.

Of the 17,000 people who signed up for the course, “Mechanics ReView,” through edX, about 1,000 earned certificates of completion. Learning gains were assessed by comparing the results of tests administered to the students before and after the course, a methodology that researchers said had never before been applied to a MOOC.

According to study co-author John Champaign, the highly automated nature of MOOCs allows user interface parameters to be closely monitored. Based on the resulting data, the three researchers have also recently published a study where they found a negative correlation between time spent reading material or doing homework and test scores. They attributed this finding to teachers and other professionals taking the course to evaluate it. In the near future, they plan to develop a course specifically for high school physics students from which they hope to extract what Pritchard calls “cleaner data.”

Since the term was coined in 2008, MOOCs have become a formidable force in the education industry. EdX, an open courseware collaboration originally formed by MIT and Harvard, boasts hundreds of thousands of unique users annually. Many other websites offer similar quality content, including Coursera and Udacity, and have collectively enrolled millions of students.

“I think we’re just barely learning how to create these tools, and they have a lot of potential even if they’re not for everyone,” said Colin Fredericks, an author of the paper and a course developer for HarvardX.
