Google Scholar does not allow you to filter your results to peer-reviewed journals. If you use Google Scholar, remember to check for peer-review by putting the journal title into Ulrichsweb.
Not sure if a particular journal is peer-reviewed? Check out Ulrichsweb. This database (also found in the A-Z database list from "Quick Links" on the library website) provides detailed information on publications. Look for the referee icon to indicate it is a peer-reviewed journal.
The black and white “ref jersey” icon in the screenshot below indicates that Higher Education is a peer-reviewed journal, but Education Week is not.
