Yes. Most people use "peer-reviewed" and "scholarly" to mean the same thing. Your instructor is asking you to find research articles that have gone through a rigorous publication process. The article and its research methods have been thoroughly reviewed by "peers" in the same field of study. For instance, if a researcher has written an article about the results of their psychology research and submitted the article to a peer-reviewed journal, other professional psychologists review that article to determine whether or not it should be published. Once the reviewers give it their stamp of approval, the article is published and shared with the whole scientific community.
The easiest way to find peer-reviewed articles is to use the article and eBook search box on the library homepage. After typing in your keywords and hitting the 'go' button, you can then limit your results to only peer-reviewed articles by selecting the "Peer-Reviewed" limiter on the left.
