Literature review of at least 3-5 sources presented in an integrative and critical fashion, and a revised reference page (only those 3-5 sources referenced in the paper should be cited), plus a bibliography, maintaining APA style. It will be a review of the literature directly related to the topic or problem under study. The purpose of the literature review is to know what others have discovered before you begin your investigation of your own, to ground your study in a particular context of what is known about a subject in order to establish a foundation for the topic (or question) being researched.
