Our most general, interdisciplinary database—meaning it has publications from all different subjects—is Academic Search Complete, so start with that one. You say "magazine," and I'm not sure if you mean a popular magazine or an academic journal. We've got a guide that explaining the differences. If you really mean a popular magazine, then after you do a search, look on the left of the database and you'll see a section called "Source Types." You can click "Magazines" to limit to that format.
Given that you are working on an education topic, though, I'd take a look at Education Research Complete. I did a search using the subject term for online courses and the word "face" (thinking of the phrase "face to face") and got pretty good results.
