When searching the databases for articles, do not type in whole sentences. After finding your topic, use some of the questions under the Find a Topic page to formulate search questions.
e.g. Topic: Benefits of Charter School on Children
searches:
Charter School and History
Charter School and Debate
Charter School and Benefits
Charter School and Negative Effects
Charter School and Economy
Charter School and Public Opinion
Think of words that mean the same thing or something similar to your topic and try searching those words too.
if you want to search for other persuasive articles (outside of CQ Researcher and Opposing Viewpoints) add an additional term such as Editorial, Opinion, Debate, Commentary etc.
