Take what you have learned from a Google search or Wikipedia article and dig deeper. Check out the sources on the article, use keywords from your internet search to search an academic database, or ask an expert whether or not what you learned is valid and if it is, where you can find a reliable source stating the same thing. So, just to be clear: you can use Wikipedia as a starting point in your research, but you should not cite Wikipedia as one of the primary sources for your research paper.
If you want to find helpful and reliable sources of information, the library is literally the best place to look around. There are numerous books, published articles, journals and etc. that you can choose from about your chosen topic.
It is also very important not to be too vague. Don’t be afraid to make a strong statement. If you look at the above examples, each of them makes a specific point about the topic. Another key to crafting a strong thesis statement is making sure that your thesis is arguable. That doesn’t mean it’s controversial or particularly opinionated, but it does mean that someone could disagree.
Spend time going over the assignment. Look at everything your instructor has provided you with. Carefully read the writing assignment, prompts, grading rubric, or any other materials you’ve received. It might even be helpful to highlight and take notes on the assignment.
As you read and evaluate the information you discover, take notes. Keep track of your reference materials so you can cite them and build your bibliography later. The Purdue Online Writing Lab (OWL) and other university writing lab websites are excellent resources to help you understand what information you’ll need to collect to properly cite references.
