Appropriate thesis topics can differ according to different variables. Every field of study has unique requirements and guidelines as to what makes for an acceptable thesis topic. Psychology programs, for example, usually require students to stick to specialized psychology topics that are closely aligned with their chosen specialty field. Childhood psychology majors would be more likely to discuss topics pertaining to children's psychology, parapsychologist majors would adhere to topics within the field of parapsychology and so on.
Selecting two to three choices for thesis topics allows you to have a backup plan in the event that your professors reject any of your ideas. Remember to pick topics that interest you, as accurately developing your thesis will require hours of research and can take up to a year or more to finish accurately.
If you have difficulty finding a thesis topic of interest, consult your professors or department chair for assistance. Remember, your thesis is an original contribution to the field of knowledge in which you are studying, so a strong interest and desire to thoroughly research your theory/theories is highly important.
Structure your thesis according to guidelines provided by your university or college. According to S. Joseph Levine, Ph.D. and professor at Michigan State University, you should first write "those parts you know best," even if they are out of order, and use these sections to build the rest of your thesis upon. Organize all of your materials so that you can easily assemble your thesis in the proper order as you begin finalizing your drafts and final product.
Remember who your audience is. Your educational professors are highly trained in dissecting research and well-researched arguments. Create thesis arguments supported by strong facts to strengthen your argument. Pace yourself and your progress so that you don't get burned out while you develop your thesis. Use the writing tutors and writing center resources available at your school to assist you in creating a thesis that is free of spelling and grammatical errors.
