Academic articles are published in academic journals. Academic articles are those that are reviewed by several experts in their related fields and then published in academic journals. There are academic journals for each subject area. The main purpose of academic journals is to represent and disseminate research and academic debates between academics (professors, researchers, students) within and between different academic disciplines.
In many cases, teachers will require that students use articles from “peer-reviewed journals.” Sometimes, the phrases “refereed journals” or “academic journals” are used to describe the same type of journals. If you've used the four methods above to try to determine if an article comes from a peer-reviewed journal and you're still not sure, talk to your instructor. But what are peer-reviewed (or refereed or academic) journal articles and why do professors do they demand their use?.
