The "Conclusions" section of a research paper should be written precisely and it must includes all findings, important results, recommendations, and future scope if any.
The formatting of an article may vary from publishers. The classic suggestion of a research article template includes: abstract, keywords, introduction, material and methods, results and discussion, conclusions and references. Some publishers reverse the order of section, suggest the fragmentation of the results and discussion, in other words, there is no formal rigor. Particularly, I prefer this suggested order, since each section facilitates the immediate reading and interest of the researcher. The conclusion is a closing or crowning of the article. When this section does not exist, the reader attempts to search the abstract (often limited in the number of words) or has to read the discussion section and exit information mining. Therefore, this issue could be systematized and formatted for all journals making life easier for authors and researchers.
The conclusions should be written precisely. In the conclusion, you must restate your aims and objectives and summarize your main findings and evidence for the reader. You should not present any new arguments in your conclusion. You can raise some open questions and set the scene for the next study. The conclusion section of your research paper should include the following:
The words "conclusions" and "conclusion" have different meaning.
The "conclusion" is simply the final thoughts at the end of the paper, and should not be lengthy.
The "conclusions" are the lessons learned from critical thinking about your findings, and should represent a significant part of your discussion section. The discussion itself should be long.
