Describe why certain medical conditions prohibit blood donation.. Ashford 6: – Week 5 – Discussion
Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses.
A Note about Earning Full Credit on Discussions:
As you participate in discussions throughout this course, remember that your responses must be considered substantive to be awarded full credit. A quality, substantive response, must meet several criteria in order to be considered for full credit. The criteria include: length, content, relevance, proper grammar and punctuation. Your responses should add new information to the conversation (instructors and classmates do not want to read the same thing over and over), use class vocabulary, use proper APA format, clearly cite the source of information that you use, be free of major grammatical errors, and be coherent (easily and quickly understood and without contradictions). Substantive responses should not be based solely on opinion, but should reflect the content of the reading assignment for the current lesson. It is also appropriate to include personal experience/examples and/or information from outside sources that support the content from the assigned reading. A substantive post to an online discussion forum will almost always be more than one or two sentences, will contain new information or will ask questions that will continue the discussion. Short statements like “I agree” or “good work” are not considered to be substantive and will not receive full credit.
