Your thesis should express the main idea of your paper without listing all of your reasons or outline your entire paper. It should be a simple statement, rather than a list of support; that’s what the rest of your paper is for!
Any information that doesn’t fit within the framework of your outline, and doesn’t directly support your thesis statement, no matter how interesting, doesn’t belong in your research paper. Keep your focus narrow and avoid the kitchen sink approach. (You know, the one where you throw in every bit of interesting research you uncovered, including the fungal growth in the U-joint of your kitchen sink?) Everything you learn may be fascinating, but not all of it is going to be relevant to your paper.
An innovative approach of research paper can give you the edge among other students. A topic should address the matter from a different and surprising perspective. With a deep investigation, you may even find the unknown until now facts that can blow your readers’ minds. This approach will intrigue your readers and will make research paper stand out.
Although it may seem counter-intuitive, writing your introduction first may be more difficult to accomplish than starting with the meat of your paper. Starting by writing the main points (focusing on supporting your thesis) allows you to slightly change and manipulate your ideas and commentary.
