How to draft a thesis proposal
Choose your topic.
You might begin with a vague idea of what you want to research. You will need to define a topic that has interest in your field, can fill a gap in knowledge, and has a manageable scope.
The topic should interest you and be something you are capable of researching and writing about. For example, you can start with the general idea that you want to write about how children are portrayed in 19th century russian literature and your favorite authors are turgenev and tolstoy.
