1、Scientific paper structureWhy a Scientific Format?The scientific format may seem confusing for the beginning science writer due to its rigid structure which is so different from writing in the humanities. One reason for using this format is that it is a means of efficiently communicating scientific
2、findings to the broad community of scientists in a uniform manner. Another reason, perhaps more important than the first, is that this format allows the paper to be read at several different levels. For example, many people skim Titles to find out what information is available on a subject. Others m
3、ay read only titles and Abstracts. Those wanting to go deeper may look at the Tables and Figures in the Results, and so on. The take home point here is that the scientific format helps to insure that at whatever level a person reads your paper (beyond title skimming), they will likely get the key re
4、sults and conclusions.Top of pageThe Sections of the PaperMost journal-style scientific papers are subdivided into the following sections: Title, Authors and Affiliation, Abstract, Introduction, Methods, Results, Discussion, Acknowledgments, and Literature Cited, which parallel the experimental proc
5、ess. This is the system we will use. This website describes the style, content, and format associated with each section.The sections appear in a journal style paper in the following prescribed order:Experimental process Section of Paper What did I do in a nutshell? Abstract What is the problem? Intr
6、oduction How did I solve the problem? Materials and Methods What did I find out? Results What does it mean? Discussion Who helped me out? Acknowledgments (optional) Whose work did I refer to? Literature Cited Extra Information Appendices (optional) Section Headings:Main Section Headings: Each main s
7、ection of the paper begins with a heading which should be capitalized, centered at the beginning of the section, and double spaced from the lines above and below. Do not underline the section heading OR put a colon at the end.Example of a main section heading:INTRODUCTIONSubheadings: When your paper
8、 reports on more than one experiment, use subheadings to help organize the presentation. Subheadings should be capitalized (first letter in each word), left justified, and either bold italics OR underlined.Example of a subheading:Effects of Light Intensity on the Rate of Electron TransportTop of pag
9、eTitle, Authors Names, and Institutional Affiliations1. Function: Your paper should begin with a Title that succinctly describes the contents of the paper. Use descriptive words that you would associate strongly with the content of your paper: the molecule studied, the organism used or studied, the
10、treatment, the location of a field site, the response measured, etc. A majority of readers will find your paper via electronic database searches and those search engines key on words found in the title.2. Title FAQs3. Format:The title should be centered at the top of page 1 (DO NOT use a title page
11、- it is a waste of paper for our purposes); the title is NOT underlined or italicized. the authors names (PI or primary author first) and institutional affiliation are double-spaced from and centered below the title. When more then two authors, the names are separated by commas except for the last w
12、hich is separated from the previous name by the word ”and”. For example:Ducks Over-Winter in Colorado Barley Fields in Response to Increased Daily Mean TemperatureIma Mallard, Ura Drake, and Woodruff DucqueDepartment of Wildlife Biology, University of Colorado - BoulderTop of pageThe title is not a
13、section, but it is necessary and important. The title should be short and unambiguous, yet be an adequate description of the work. A general rule-of-thumb is that the title should contain the key words describing the work presented. Remember that the title becomes the basis for most on-line computer
14、 searches - if your title is insufficient, few people will find or read your paper. For example, in a paper reporting on an experiment involving dosing mice with the sex hormone estrogen and watching for a certain kind of courtship behavior, a poor title would be:Mouse BehaviorWhy? It is very genera
15、l, and could be referring to any of a number of mouse behaviors. A better title would be:The Effects of Estrogen on the Nose-Twitch Courtship Behavior in MiceWhy? Because the key words identify a specific behavior, a modifying agent, and the experimental organism. If possible, give the key result of
16、 the study in the title, as seen in the first example. Similarly, the above title could be restated as:Estrogen Stimulates Intensity of Nose-Twitch Courtship Behavior in Mice4. Strategy for Writing Title.Top of pageABSTRACT 1. Function: An abstract summarizes, in one paragraph (usually), the major a
17、spects of the entire paper in the following prescribed sequence:the question you investigated (or purpose), (from Introduction) state the purpose very clearly in the first or second sentence. the experimental design and methods used, (from Methods) clearly express the basic design of the study. Name
18、 or briefly describe the basic methodology used without going into excessive detail-be sure to indicate the key techniques used. the major findings including key quantitative results, or trends (from Results) report those results which answer the questions you were asking identify trends, relative c
19、hange or differences, etc. a brief summary of your interpetations and conclusions. (from Discussion) clearly state the implications of the answers your results gave you. Whereas the Title can only make the simplest statement about the content of your article, the Abstract allows you to elaborate mor
20、e on each major aspect of the paper. The length of your Abstract should be kept to about 200-300 words maximum (a typical standard length for journals.) Limit your statements concerning each segment of the paper (i.e. purpose, methods, results, etc.) to two or three sentences, if possible. The Abstr
21、act helps readers decide whether they want to read the rest of the paper, or it may be the only part they can obtain via electronic literature searches or in published abstracts. Therefore, enough key information (e.g., summary results, observations, trends, etc.) must be included to make the Abstra
22、ct useful to someone who may to reference your work.Top of pageHow do you know when you have enough information in your Abstract? A simple rule-of-thumb is to imagine that you are another researcher doing an study similar to the one you are reporting. If your Abstract was the only part of the paper
23、you could access, would you be happy with the information presented there?2. Style: The Abstract is ONLY text. Use the active voice when possible, but much of it may require passive constructions. Write your Abstract using concise, but complete, sentences, and get to the point quickly. Use past tens
24、e. Maximum length should be 200-300 words, usually in a single paragraph.The Abstract SHOULD NOT contain:lengthy background information, references to other literature, elliptical (i.e., ending with .) or incomplete sentences, abbreviations or terms that may be confusing to readers, any sort of illu
