DISCUSSION ASSIGNMENT INSTRUCTIONS
The student will complete Integrating Faith and Learning discussion. 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 and support their assertions with scholarly citations in the latest APA format. Minimum word count for all short answers cumulatively is 200 words. The minimum word count for Integrating Faith and Learning discussion is 600 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 your response; use Level Two headings for multi part questions (e.g. D1.1 & D1.1.a, D1.1.b, etc.), and include a reference section. The student must then post 1 reply to another student’s post. The reply must summarize the student’s findings and indicate areas of agreement, disagreement, and improvement. It must be supported with scholarly citations in the latest APA format and corresponding list of references. The minimum word count for Integrating Faith and Learning discussion reply is 250 words.
