Main body of dissertation should include three parts: analytical, theoretical and practical, which can be formed in 2-4 chapters.
Analytical part should present author’s review of all literature and research works on his topic. You need to conduct critical analysis of these data. After this you can highlight range of issues that you think are not disclosed, not discovered at this moment, require further study, etc. To create paragraph that will sum up this section, you can make conclusions about need for further investigation of this matter.
Theoretical part should define research queries. Describe what research method you will use, and provide detailed plan of studies.
Practical part should provide results of calculations, experiments, and observations that you've done during your research and give an accurate analysis of collected data.
As conclusion of your dissertation you need to confirm validity of gathered info and research results and give readers some ideas about how your findings can be used in theoretical and practical fields of science.
To understand how to write a science dissertation you need to be aware that paper doesn’t have to be very long, it is sufficient if body of your text will be presented in 100-120 pages. You must ensure that your work doesn't include plagiarism. Therefore, it is important to do your own research and to present studied data in your own words, without copying individual sections or suggestions from various sources. If plagiarism is found, your work can be rejected or receive low grade.
Key to success of good dissertation is knowledge of what other discoveries were made in your field; many students find it difficult and face issues with finding relevant data. Thanks to computers and the Internet, search of literature has changed dramatically in recent years. Instead of visiting library, students can use their computers to find needed info. However, not all databases have open access, some of them require permit; you should ask your professor to give you this special permit to access such sources or find out what analogous sources you can use, it will be a real help with a dissertation, because data with closed access is used very rarely.
Thesis must clearly and logically explain content and results of the study, avoid common phrases, tautology, and distortion of facts.
Sample structure of your future work can be following: title page, list of content, list of abbreviations (if you need them), introduction, main body (should consist of several chapters with subheadings and subparagraphs), conclusion, list of references.
Some rules of structuring of scientific theses differ depending on region and your school. Demands for paper formatting such as font, space between lines, size of letters and volume of work, you should check with your teacher.
