Instructions: Your response to the initial question should be 250-300 words. Next respond to two postings provided by your classmates. There must be at least one APA formatted reference (and APA in-text citation) to support the thoughts in the post as needed. Do not use direct quotes, rather rephrase the author’s words and continue to use in-text citations.

Please ensure the initial post and two response posts are substantive, not the same for both classmates, and have enough details to show us that you read the posting and have original feedback to offer. Substantive posts will do at least TWO of the following: Ask an interesting, thoughtful question pertaining to the topic Expand on the topic, by adding additional thoughtful information Answer the question posted by another student in detail, and I say again (IN DETAIL). A simple two-line response will not earn you credit for your reply, and I will deduct points accordingly. Under NO circumstance will late work be accepted for any reason at all. Please complete all work and all assignments early in the week to avoid issues and conflicts. I will refer you back to this message if you ask me, and I will not entertain the discussion even if your power was out on the last day your assignment or discussion was due.
