A research paper usually follows a particular structure. The beginning paragraph or introduction is a general overview of the topic that eventually leads into a clear thesis. This is followed by the body of the paper that demonstrates the argument for the thesis and is the bulk of the paper. Finally, there is a conclusion that summarizes the main points of the paper and makes a connection back to the original thesis.
The style of a research paper is typically academic and formal. It should be written in the third person voice and should remain objective in tone. A research paper is simply a presentation of the facts that support an argument, but the argument is not demonstrated as the personal opinion of the writer. Instead, the writer presents the thesis as a statement of fact and then proceeds to explain why the thesis is true, based on the evidence he or she cites in the paper.
Authoritative sources are the backbone of an effective research paper. Regardless of the topic, a paper should be supported by evidence from trusted sources. Academic journals or the publications of professional organizations are usually the most appropriate sources to cite in the paper. Additionally, it is best to use sources that have been published in the past 10 to 25 years, unless the topic is related to a specific time period.
A research paper must have proper citation of sources. There are different styles of citation, such as MLA or APA, but it's important to be consistent. It's acceptable to use the information of sources in the paper without putting it in quotations, but it still must be cited in the paper. Some disciplines actually encourage papers to have minimal direct quotes from sources. Since the paper is persuasive in nature, it's best to put information from sources in your own words and cite appropriately. Also, make sure to include an appendix or works cited page at the end of the paper.
