Scholarly articles are published in scholarly journals and are sometimes called peer-reviewed articles. The articles are a means for a scholar to communicate with other scholars in the field about his or her research. They are often reviewed by peers in the field in order to ensure that the article is relevant and accurate.
Brief but excellent video from North Carolina State University explains what peer review is and why it is important.
