Academic resources, such as journals, academic books, and dissertations, undergo a formal evaluation process before publication. The peer review process is used by most scholarly journals, such as the New England Journal of Medicine. This helps to ensure high quality information and accuracy of results. Peer reviewed simply means that the manuscript has been reviewed by experts in the field. See the Springer Nature Peer-Review Policy link below for an example of the way one journal conducts their peer review process. Scholarly peer reviewed work and other published research (dissertations, scholarly books, etc.) attempt to add to the body of knowledge. That said, even though an scholarly article has been peer reviewed, it is still important that you critically evaluate it yourself, as some journals differentiate in acceptance standards.
Remember that most of your resources for University work should be scholarly RESEARCH articles. A scholarly journal has additional sections like any other journal: editorials, book reviews, news, letters, etc. These resources are not considered research articles, even though they are published in a scholarly/peer reviewed journal. You will want to make sure that you are focusing your efforts primarily on the original, research-based articles.
Characteristics of scholarly studies:
Popular resources do not typically go through the same review process as academic resources; in many cases popular resources are reviewed by a single editor, who may or may not have expertise in the subject area. Popular resources are usually written for a broad audience and do not always use the same, formal language as authors of academic articles.
Examples of popular resources include magazine and newspaper articles, websites, and wikis. Use popular resources to identify the latest trends and issues within your topic but do not rely heavily on these types of resources.
