Typical research essay assignment follows classic academic writing structure, which includes introduction with a thesis statement, three to five body paragraphs, and conclusion. In simple terms, research paper aims to analyze published academic works for ideas related to chosen subject in order to compare it with personal opinion and findings. An argument that writer finds the most crucial should be included in a thesis statement at the end of Introduction part. This is the heart of any research essay. A rule of thumb is to use academic sources to support each idea, which is not author's personal contribution to avoid plagiarism risks. Both introduction and conclusion should mention why an essay in question is significant. Check these research paper samples.
