The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered.
For this assignment, make sure you post your initial response to the Discussion Area by the due date assigned.
To support your work, use your course and text readings and also use outside sources. As in all assignments, cite your sources in your work and provide references for the citations in APA format.
Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates. Participate in the discussions (which are your peer responses) by providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or by indicating a relationship between two or more lines of reasoning in the discussion. Your peer responses should be about 150 words each, follow APA format, and include academic citations. Complete your participation for this assignment by the end of the week.
