Make sure you understand what a dissertation is before you undertake one. It is a long and structured essay which is often so long that it has chapters (like a book). It is less like an essay and more like a research paper. You are tasked with creating a thesis and then proving it. You can only do this with research and reasoning. You are then supposed to turn this research and reasoning into arguments that plead your case (aka prove your thesis correct).
Not only is your work supposed to prove a thesis, you must show how you proved it. You must research to find your evidence. Then you must analyze your evidence to create your arguments. It is only then that you must conclude upon your arguments. This is what proves your thesis. Not only that, but it is often expected that you do this with a text of around twelve thousand words. If you need a little help in this mammoth task then why not call upon the services of dissertation-service.org. They will help you to organize your thoughts and help to ensure that your research is heading down the right path, because there is nothing worse than spending weeks on research - only to find that it is irrelevant.
The dissertation process is not structured in the same way for every subject or discipline. For example, a biology or chemistry dissertation may involve the creation of a topic and then the repeated testing of that topic to act as evidence for the topic, whereas something such as humanity or history would have a very standard dissertation process.
A more generic process starts with a thesis statement. This derived from your chosen topic. Even though the thesis should be in the first paragraph of your dissertation, it is not the first thing you think of. The first step is to pick a topic and research it. Through your research you may start to build a thesis statement. This preliminary research is good for organizing your thoughts. Once you have your thesis statement you need to spend some time explaining the issue and problems. You will probably also have to give some background information and explain how you came to choose your topic.
Now it is time to start collecting evidence to prove your dissertations thesis. This involves targeted research. Your aim is to use this research to prove the arguments you make in your text. The evidence is analyzed. You must then show your reasoning in order to indicate how you got from your research and evidence, to your arguments (and main points). Your arguments must then be put to the test, analyzed and concluded upon. The conclusion brings together all of your argument and uses them to prove your thesis. The process involves research and analysis from the ground up, but keep in mind to make sure there are no holes in your reasoning or research then you should come away with a good grade.
