Before trying to understand the scholarly and peer-reviewed articles, get a firm grasp of your topic with definitions, topic overviews, and information written with the learner in mind.
Whether you're looking for peer-reviewed or just credible scholarly sources, most library databases allow you to limit your search results to just these kinds of articles. Take a look at some of these databases to get started.
Remember: there's a difference between scholarly and peer-reviewed. Scholarly is a much broader category and can include books, articles, reviews, opinion pieces, and more. Peer-reviewed refers to a specific process in which an article is evaluated by scholars before it is approved for publication.
