Post an original post to the discussion board no later. For the next four posts, discuss other students’ explanations of their choice, challenging them (politely, please!) where you may see problems or difficulties in the future. Suggestions for changes or additions would be helpful. Simply stating “nice job” or “I agree with you” will not earn full credit. You must respond with a meaningful example, new thought, or personal story to support your agreement or disagreement with your fellow classmate’s post.
