We may start by comparing it to an ordinary essay, a form of writing you are very familiar with. Writing a research paper is much like writing an essay. Both kinds of writing involve many of the same basic steps. That is, choosing a topic, asking questions to define and develop the topic, identifying the audience, getting raw material to work with, outlining the paper, writing it, and, finally, revising it. These are the steps shared between research paper writing and essay writing.
家常做法Is there any difference, you may ask. Yes. What makes a research paper different is that much of your raw material comes not from your own head, but from printed sources: mainly books and periodicals in the library. Collecting raw material, that is reading books and taking notes, is very much like the process of brainstorming at the prewriting stage of an ordinary essay.南瓜糯米团Generally speaking, there are two basic types of research papers, and a paper may belong to either type. It may be a survey of facts and opinions available on a given topic or an analytical argument that uses those facts and opinions to prove a point. Your instructor may tell you which kind of paper you are expected to write. If not, you yourself should eventually choose between surveying and arguing. You will then have a definite way of managing your sources.
家常做法Now, let鈥檚 take a look at how you are going to write a survey-type research paper or an argumentative research paper. In a survey-type research paper, you gather facts and a variety of opinions on a given topic. You make little attempt to interpret or evaluate what your sources say or to prove a particular point. Instead, through quotation, summary, and paraphrase, you try to provide a representative sampling of facts and opinions to give an objective report on your topic. You explain the pros and cons of various attitudes or opinions, but you don鈥檛 side definitely with any one of them.南瓜糯米团While in an argumentative research paper, you do considerably more. You do not simply quote, paraphrase, and summarize as you do in a survey-type paper. You interpret, question, compare, and judge the statements you cite. You explain why one opinion is sound and another is not; why one fact is relevant and another is not; why one writer is correct and another is mistaken. What鈥檚 more, your purpose may vary with your topic. You may try to explain a situation to recommend a course of action, to reveal the solution to a problem, or to present and defend a particular interpretation of a historical event or a work of art. But whether the topic is space travel or trends in contemporary American literature, an argumentative research paper deals actively 鈥 I say it again, actively 鈥 with the statements it cites. It makes these statements work together in an argument that you create, that is, to an argument leading to a conclusion of your own.
