  8. 2. Title • Make your title specific enough to describe the contents of the paper, but not so technical that only specialists will understand. • The title should be appropriate for the intended audience. • The title should be short, avoiding the inclusion of details. • Use generic titles • The title usually describes the subject matter of the article: Effect of Smoking on Academic Performance • Sometimes a title that summarizes the results is more effective: Students Who Smoke Get Lower Grades

  9. 3. Authors • The person who did the work and wrote the paper is generally listed as the first author of a research paper. • Other people who made substantial contributions to the work are also listed as authors. • Ask your supervisor's permission before including his/her name as co-author.

  10. 4. Affiliation • Claudia Muster1 , Bob Smith2, Richard F.

  11. 5. Abstract • The abstract should be a little less technical than the article itself; you don't want to dissuade your potential audience from reading your paper. • The abstract should be one paragraph, of 100-250 words, which summarizes the purpose, methods, results and conclusions of the paper. • It is not easy to include all this information in just a few words. Start by writing a summary that includes whatever you think is important, and then gradually prune it down to size by removing unnecessary words, while still retaining the necessary concepts. • Don't use abbreviations or citations in the abstract. It should be able to stand alone without any footnotes.

  12. 5. Abstract In elementary schools, the prevalence of bullying ranges from 11.3% in Finland to 49.8% in Ireland. The only United States study of elementary students found that 19% were bullied. Bullying behavior declines as students progress through the grades. School bullying is associated with numerous physical, mental, and social detriments. A relationship also exists between student bullying behavior and school issues such as academic achievement, school bonding, and absenteeism. Prevention of school bullying should become a priority issue for schools. The most effective methods of bullying reduction involve a whole school approach. This method includes assessing the problem, planning school conference days, providing belter supervision at recess, forming a bullying prevention coordinating group, encouraging parent-teacher meetings, establishing classroom rules against bullying, holding classroom meetings about bullying, requiring talks with the bullies and victims, and scheduling talks with the parents of involved students. Finally, this review suggests further studies needed to help ameliorate the bullying problem in US schools. Total number of words: 157

  13. 6. Keywords • Title paper: Economic growth and human development • Keywords: Human development, economic growth, income distribution, poverty, health, education • Title paper: Heavy metal contaminations in a soil–rice system: Identification of spatial dependence in relation to soil properties of paddy fields • Keywords: Contamination, geostatistics, heavy metals, soil–rice system, spatial relationship • Title paper: Sources of China’s economic growth 1952–1999: incorporating human capital accumulation • Keywords: China, economic growth, human capital, reform

  14. 7. Introduction • What question did you ask in your experiment? • Why is it interesting? • The introduction summarizes the relevant literature (please include a sufficient number of references of recent date; e.g. the last decade) so that the reader will understand why you were interested in the question you asked. • End with the formulation of the hypotheses which you want to approve/disapprove.

  15. 7. Introduction • End of the introduction: …………………….. The objective of our study was two-fold: (1) to characterize the implementation of the OBPP in the seven schools, and (2) to compare schools with (N 7) and without (N 3) the OBPP to determine if the program was effective with regard to: (a) reducing student reported victimization (primary outcome), (b) improving student attitudes toward bullying and perceptions of others’ readiness to intervene (key program targets), and (c) improving the general school experience beyond bullying.

  30. 9. Materials and methods • How did you answer this question? There should be enough information here to allow another scientist to repeat your experiment. Look at other papers that have been published in your field to get some idea of what is included in this section. • If you had a complicated protocol, it may helpful to include a diagram, table or flowchart to explain the methods you used.

  31. 9. Materials and methods • Do not put results in this section. You may, however, include preliminary results that were used to design the main experiment that you are reporting on. ("In a preliminary study, I observed the owls for one week, and found that 73 % of their locomotor activity occurred during the night, and so I conducted all subsequent experiments between 11 pm and 6 am.") • Mention relevant ethical considerations. If you used human subjects, did they consent to participate. If you used animals, what measures did you take to minimize pain?

  32. 10. Results • This is where you present the results you've gotten. Use graphs and tables if appropriate, but also summarize your main findings in the text. Do NOT discuss the results or speculate as to why something happened; t hat goes in the Discussion. • You don't necessarily have to include all the data you've gotten. Make a selection of the most relevant results. • Use appropriate methods of showing data. Don't try to manipulate the data to make it look like you did more than you actually did.

  33. 11. Tables, graphs, photos, maps

  34. 11. Tables, graphs, photos, maps

  35. 11. Tables, graphs, photos, maps

  36. 11. Tables, graphs, photos, maps

  37. 11. Tables, graphs, photos, maps

  38. 11. Tables, graphs, photos, maps

  39. 11. Tables, graphs, photos, maps

  40. 12. Discussion • Highlight the most significant results, but don't just repeat what you've written in the Results section. How do these results relate to the original question? Do the data support your hypothesis? Are your results consistent with what other investigators have reported? If your results were unexpected, try to explain why. Is there another way to interpret your results? What further research would be necessary to answer the questions raised by your results? How do y our results fit into the big picture? • End with a one-sentence summary of your conclusion, emphasizing why it is relevant.

  41. 13. Conclusions • Strategies to apply: • Return to the theme or themes in the introduction. This strategy brings the reader full circle. For example, if you begin by describing a scenario, you can end with the same scenario as proof that your essay is helpful in creating a new understanding. You may also refer to the introductory paragraph by using key words or parallel concepts and images that you also used in the introduction. • Synthesize, don't summarize: Include a brief summary of the paper's main points, but don't simply repeat things that were in your paper. Instead, show your reader how the points you made and the support and examples you used fit together. Pull it all together.

  42. 13. Conclusions • Include a provocative insight or quotation from the research or reading you did for your paper. • Point to broader implications. For example, if your paper examines the Greensboro sit-ins or another event in the Civil Rights Movement, you could point out its impact on the Civil Rights Movement as a whole. A paper about the style of writer Virginia Woolf could point to her influence on other writers or on later feminists.

  43. 13. Conclusions • Strategies to avoid: • Beginning with an unnecessary, overused phrase such as "in conclusion," "in summary," or "in closing." Although these phrases can work in speeches, they come across as wooden and trite in writing. • Stating the thesis for the very first time in the conclusion. • Introducing a new idea or subtopic in your conclusion. • Ending with a rephrased thesis statement without any substantive changes. • Making sentimental, emotional appeals that are out of character with the rest of an analytical paper. • Including evidence (quotations, statistics, etc.) that should be in the body of the paper.

  44. 13. Conclusions • Strategies to avoid: • Sometimes writers will state the thesis for the very first time in the conclusion. You might be tempted to use this strategy if you don't want to give everything away too early in your paper. You may think it would be more dramatic to keep the reader in the dark until the end and then "wow" him with your main idea, as in a Sherlock Holmes mystery.

  45. 14. Acknowledgements • This section is optional. You can thank those who either helped with the experiments, or made other important contributions, such as discussing the protocol, commenting on the manuscript, or buying you pizza. • Example: We thank Vinod Thomas for the encouragement, Aart Kraay, two anonymous referees, and the editor of the journal for comments, and Ashok M.
