Responding to a classmate’s post requires both the addition of new ideas and analysis. A particular point made by the classmate must be addressed and built upon by your analysis in order to move the conversation forward.
Thus, the response post is a rigorous assignment that requires you to build upon initial posts to develop deeper and more thorough discussion of the ideas introduced in the initial posts.
As such, reply posts that merely affirm, restate or unprofessionally quarrel with the previous post(s) and fail to make a valuable, substantive contribution to the discussion will receive appropriate point deductions.
