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.
The Education Department examined all kinds of instruction, and found that the number of valid analyses of elementary and secondary education was too small to have much confidence in the results. But the positive results appeared consistent (and statistically significant) for all types of higher education, undergraduate and graduate, across a range of disciplines, the study said.
A meta-analysis is one that takes all of the existing studies and looks at them for patterns and conclusions that can be drawn from the accumulation of evidence.
On the topic of online learning, there is a steady stream of studies, but many of them focus on limited issues or lack control groups. The
