The research behind SpacedEd was developed by B. Price Kerfoot, an associate professor of surgery at Harvard Medical School.
His previous research had demonstrated that people are more likely to retain information when they see it periodically and are tested on their knowledge, rather than simply provided with reading material.
Kerfoot said he has tested the method in more than a dozen trials with 7,000 medical students, doctors and other participants . Overall results have indicated that it helped them boost their knowledge and retain it for up to two years.
In one study, two randomly divided groups of 240 physicians each took a course about clinical practice guidelines in urology.
One group was presented a section of the material three times at spaced intervals over 20 weeks.
By the end, that group demonstrated a 50 percent increase in knowledge of that material compared with the control group.
Kerfoot said that the method has also proved to be an effective teaching tool for medical students from Baylor University, the University of Pittsburgh, Harvard and several other institutions.
Beyond medicine, Kerfoot said its testing method can be applied to fields across higher education.
SpacedEd currently has more than 2,000 users and two dozen courses, all of them free (though authors can charge and earn a slice of the revenue) and none of them for academic credit.
Any registered user can construct lessons about anything, including non-science subjects like bartending, music theory and copyright law.
Site administrators rely on users' comments to check for accuracy and clarity, Kerfoot said.

A colleague of Kerfoot, she said she does not usually use online education systems, but likes being able to embed images and audio on SpacedEd.
Above all, she said, the site simplifies the learning process.

Those who took courses that combined online learning and face-to-face instruction performed best of all . The technology based on Kerfoot's research is patented by Harvard.
