Some key characteristics will help you distinguish between research and review articles. A research article is describes an experiment that attempts to solve or address a very specific problem/issue. These articles always contain the standard sections:
Abstract - This is a brief paragraph description of the inner-workings of the article. The abstract allows scholars and scientists to ascertain what the article is about in just a few seconds.
Introduction - This section states the purpose of the article, defining the problem and putting it into context. It may include a review of the published literature on the topic.
Review of literature - This section is usually located just after the research description. The review summarizes the results of other experiments that have been done in the past.
Method - This section contains a detailed description of the approach the researchers have taken to test the idea, problem, or issue.
Results - The Results of the experiment or test is explained after the Method description.
Discussion or Conclusion - This is where the researchers interpret the results of the experiment or test and create meaning.
The research article always ends with a "Bibliography" or "References" or "Works Cited" section.
