A lot of students and beginner researchers do not understand the significance of research proposals. To be honest, your thesis committee would judge you by the quality of your proposal. After all, it will let them know about your abilities as a researcher.
The purpose of a proposal is to convince the readers that you have a worthy project along with the competence and skill to complete it. A proposal should generally contain all the key elements and succinct information about your area of study. Moreover, the thesis committee would also infer if the student has done sufficient preliminary research about the topic under discussion. Also, that they are able to provide more than a broad description of the topic.
The research proposals are not something that will be fixed and have to be accurate. It is obvious that one cannot predict its findings before he has conducted the research and will inevitably alter initial claims. However, the committee wants you to convince them about an identified problem and the right approach to tackle that problem. It is best to discuss word limit and other small details with the authority before proceeding.
The general outline of a proposal is similar to that of a paper, however, the word limit for each section is significantly reduced. The abstract should appear on the title page that would include the topic and all the information about yourself. Abstract would be a concise summary of whatever you plan to do and should be written at the end of the research proposal.
Mention your research literature and talk about research methods you are using to conduct the research. Your proposal needs to show why the proposed research is imperative and rationalizes the search effort. Such an explanation may either be of an empirical nature that hopes to add to existing knowledge or of a theoretical nature, which hopes to explicate antagonistic areas in a subject area and to add new abstract acumens into the knowledge.
