Academic research is dense and not super easy or fun to read. Depending on your needs, there may be parts of the article you can skip. As a good rule of thumb, make sure you read the beginning and the end to get the basic understanding, then read more if necessary.
As a part of the peer-review process, research articles must include a discussion of the essential question behind the research, specifics about their methods, a detailed summary of the data, and an analysis of the data. All of this information is important for the peers considering the article for publication, for others who look to conduct similar research, and for academics critically analyzing research.
HOWEVER, when doing typical research at a high school level, the discussion and analysis of data is more important than the methods or data summary. Keep your needs in mind when reading an academic article, and focus on the sections most relevant to your needs.
Below is a description of common sections in academic research articles.
