The Evidence on Online Education - Inside Higher Ed: "Online learning has definite advantages over face-to-face instruction when it comes to teaching and learning, according to a new meta-analysis released Friday by the U.S. Department of Education. 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."
(Here is the DOE Press release and here is the full report.)
I will have to read through the full report to see how they measure things, but the results sound right to me. My online students have typically done much better than my classroom students, scoring on average a full point higher on identical finals. (Or as I usually spin it, I have statistical proof that contact with me makes students dumber.)
