Learning how to research is an important skill. The details for each step of the research process will vary depending on your assignment. Having a research strategy will help you focus your topic, organize your searches, and manage your time more efficiently.
The research process takes time and effort; you may not find what you're looking for on the first try, nor should you expect to be finished in a few hours.
When conducting research, you should be aware that not all scientific articles are the same. Here are some key features of the different types of writing you may come across in your searching:
Peer-Reviewed (Scholarly) Articles
Popular/News Articles
Abstract, Conference Publication/Presentation, Dissertation Proposal
Review Articles
Clinical Trials/Clinical Study
Meta-Analysis
Perspective/Opinion Article
Book Review
