Overview
In the thread for each short-answer discussion, the student will post short answers to the prompted questions. The answers must demonstrate course-related knowledge from the textbook and support their assertions with scholarly citations in the latest APA format. Minimum word count for all short answers cumulatively is 150-200 words. For each thread the student must include a title block with your name, class title, date, and the discussion forum number; write the question number and the question title as a level one heading (e.g. D1.1 Variables) and then provide yourresponse; use Level Two headings for multi part questions (e.g. D1.1 & D1.1.a, D1.1.b, etc.), and include a referencesection. If you choose to bring in additional scholarly sources, you may do so, but it is not expected.
