Submit your paper as a Word attachment in the discussion forum. I often provide feedback within the paper and will not grade your post unless you submit it as an attachment. Your response to the discussion prompt should contain a minimum of 500 words and it should be submitted no later than Wednesday before 11:59 pm EST.  Your response should be formatted in APA style and reference each of this week’s readings.

2. The following point allocations are used to grade all discussion papers: 5 points APA style, 5 points use of required readings, 5 points content, 5 points scholarly writing/grammar/structure. Failure to cite each week’s required readings will result in an automatic 5-point deduction. Failure to provide in-text citations of paraphrased and quoted material will result in an automatic 5-point deduction.

Follow the following writing requirements for all of your discussion prompt responses (note that these writing requirements DO NOT apply to your responses to other students):
