Review Chapter 4 of your textbook and discuss the topic. when posting your initial note you should provide, a reliable source (peer reviewed article, reliable webpage [.org, .gov, or international organization]) to support your ideas. Make sure that you use a parenthetical citation in your text and the reference at the end of your discussion using in both cases the APA citations and references style. Use the Library to find your peer reviewed articles and download your article in PDF format so you can also attach it on the bottom of your note after the APA reference so your peers are able to review it too.
