Choosing your research topic is an important step in writing your paper. First, choose a topic you're interested in. You don't want a topic that is too narrow or one that has little or no research about it. Think of a topic that will have enough articles/research relating to it. Is it significant enough that research has been done on it?
How to choose a topic? Writing different ideas down on paper can help your ideas flow. You also want a topic that piques your curiosity. Keep in mind you have to live with this topic over the course of an entire semester.
Try identifying 3 potential research topics. Consider related concepts. Then, perform a quick search on all three. From your three ideas, choose the one that is strongest. Are there enough articles available? Is the topic too general? Does the topic seem to broad or narrow?
