1 CHAPTER 3 Materials and Methods

2 This should be the easiest section to write, but many students misunderstand the purpose. The objective is to document all specialized materials and general procedures, so that another individual may use some or all of the methods in another study or judge the scientific merit of your work. It is not to be a step by step description of everything you did, nor is a section of a set of instructions. In particular, it is not supposed to tell a story.

3 A methodology is the study of, or a system of, methods. Usually you mean method instead of methodology.

4 Your materials and methodology will be specific to the particular study you are describing, but it should –describe the study clearly and thoroughly enough that someone with similar resources and skills could replicate the study accurately –be concise (which is quite a trick when you also want to be thorough) –be organized in such a way that the reader comes to understand your approach quickly and easily

5 It deals with the methods and principles used in an activity, in this case your project study. In the “materials and methodology” chapter you explain how you did the research, the methods of data collection, materials used, subjects interviewed, or places you visited.methods of data collection Give a detailed account of how and when you carried out your research. Explain why you used the particular methods which you did use, rather than other methods.

6 1. Methods of Collecting Data There are many different ways of collecting data. Which method or combination of methods you use will depend upon your subject area. These are some of the terms used to describe different methods. Case Studies Documentary research Field experiments Field Work; Participant Observation Laboratory experiments Observation and visits Qualitative Data Quantitative Data Questionnaires and surveys Statistical experimentsLaboratory experiments Observation and visits Qualitative Data Quantitative Data Questionnaires and surveys Statistical experiments

7 2. Statistical Analysis Included in the methodology section should be a thorough explanation of data and the methods by which data was obtained. Instruments of data collection vary, but common methods include surveys, interviews, questionnaires, and case studies. The writer must show methodological expertise through analyzing the benefits and limitations of every method of data collection used in preparing the project.methodology

8 3. Subject Population Included in the methodology section should be a thorough explanation and definition of the subject population (person or thing being studied). The writer must not only identify the subject population, associated demographics, and resulting data, but also acknowledge any possible biases or irregularities resulting from gender, age, race, sexuality, religious beliefs, political affiliation, educational level, etc.methodology data

9 When writing…. Generalize - report how procedures were done, not how they were specifically performed on a particular day. For example, report "samples were diluted to a final concentration of 2 mg/ml protein;" don't report that "135 microliters of sample one was diluted with 330 microliters of buffer to make the protein concentration 2 mg/ml." Always think about what would be relevant to an investigator at another institution, working on his/her own project.

10 What style of writing It is awkward or impossible to use active voice when documenting methods without using first person, which would focus the reader's attention on the investigator rather than the work. Therefore when writing up the methods most authors use passive voice. Use normal prose in this and in every other section of the paper – avoid informal lists, and use complete sentences.

11 What to avoid Materials and methods are not a set of instructions. Omit all explanatory information and background - save it for the discussion. Omit information that is irrelevant to a third party, such as what color ice bucket you used, or which individual logged in the data.

12 Use diagrams, flowcharts and graphs The cliché a picture is worth a thousand words is true. A good diagram, flowchart or graph can present information quickly that would take ten sentences to explain. A diagram makes any explanation or technical description far easier to understand.

13 SCHEDULE OF ACTIVITIES This should be presented in a tabulated form. Activities versus time. It must start from the beginning activity until it ends February next year. Be accurate of your scheduling. Follow what you have proposed in the schedule.

14 CHAPTER 5 REFERENCES

15 A bibliography is an alphabetical list of all the sources you have consulted for an essay or research paper. You must list your sources in a specific format. Use this guide to create your bibliography in the correct format. Remember: - Always underline the title of the work cited. - Alphabetize by the author’s last name. - If there is no author, alphabetize by title. - Always indent the second or third lines (5 spaces). Always leave 1 space after commas and 2 spaces after periods and colons.

16 For a book with one author: Robinson, A. (1993). What Smart Students Know. New York: Crown Paperbacks. For a book with two authors: Sorensen, Sharon, and Bob LeBreck (1994). The Research Paper. New York: Amsco Publications.

17 For a book with no author: The World of Learning. London: Europa Publications, 1995. An article in a magazine: Begley, S. (1982). "A Healthy Dose of Laughter." Newsweek 4 Oct. 1982: 74. An article in a newspaper: Brody, J. E. (1976) "Multiple Cancers Termed On Increase." New York Times 10 Oct. 1976: A37

18 An article from an internet site: Bradshaw, G.S. (1996) "Wilbur and Orville Wright." URL: http://www.wam.umd.edu/~srwright/WrBr/Wrig hts.html http://www.wam.umd.edu/~srwright/WrBr/Wrig hts.html Try to find as much information as possible about an Internet document in order to determine whether it is accurate or not. It is especially important to try to find out about the author of an Internet document, whether a person, organization or institution.
