The below databases are a great starting point for finding scholarly articles. After you run a search, look for the "peer-reviewed" filter-- this will help you return quality articles. If you have any questions, don't hesitate to contact me!
When you find an article that might be useful, read the abstract first. Then, read the introduction and conclusion. If the article still looks like a good source, then read the entire article. This will save you time if you've been reading everything from start to finish!
