The hardest part of research is getting started! Choosing a topic can be intimidating, especially in introductory classes, when you don't really know much about the subject. The most important thing to remember is this: you are doing research, so don't make a statement about what you want to prove and then go looking for evidence to support your claim. Instead, start out with an interest, read some articles on the topic and then take a stance on the subject based on what you have learned.
Here are some tips to get you started:
Some other things to consider when choosing a topic: How long does your paper need to be? A shorter paper will need a more narrowly focused idea, and a longer paper a broader one. How much time do you have? If you have several weeks, it’s likely your instructor is expecting you to do a lot of research. Do you need a a particular number or type of references? Scholarly books and articles take time to write and publish, so topics focused narrowly on a very recent event can be problematic.
