How to Write a Research Introduction. The introduction to a research paper can be the most challenging part of the paper to write. The length of the introduction will vary depending on the type of research paper you are writing. An introduction should how to write scientific research paper pdf your topic, provide context and a rationale for your work, before stating your research questions and hypothesis.

Well-written introductions set the tone for the paper, catch the reader’s interest, and communicate the hypothesis or thesis statement. This is a good way to introduce your readers to your topic and pique their interest. The first few sentences should act as an indication of a broader problem which you will then focus in on more closely in the rest of your introduction, leading to your specific research questions. In scientific papers this is sometimes known as an “inverted triangle”, where you start with the broadest material at the start, before zooming in on the specifics.

It provides the reader with an indication of the content of the essay and encourages them to read on. Consider referring to key words. You may also have certain key words in your title which you want to establish and emphasise in your introduction. For example, if you were writing a paper about the behaviour of mice when exposed to a particular substance, you would include the word “mice”, and the scientific name of the relevant compound in the first sentences. If you were writing a history paper about the impact of the First World War on gender relations in Britain, you should mention those key words in your first few lines. Define any key terms or concepts.

You need to express yourself clearly throughout your paper so if you leave an unfamiliar term or concept unexplained you risk your readers not having a clear understanding of your argument. This is especially important if you are attempting to develop a new conceptualization that uses language and terminology your readers may be unfamiliar with. Introduce the topic through an anecdote or quotation.
