Final answer:
To earn maximum points on a discussion board, include 6 or 7 meaningful sentences per reply, respond to at least two other students, avoid last-minute postings for full credit, reply early and often, and for extra points, engage with more than two classmates.
Step-by-step explanation:
To earn the maximum points for postings on the discussion board about '50 Great Myths', students should follow a few key guidelines. First, ensure each reply contains 6 or 7 meaningful sentences that are directly related to the content of the article being discussed. Merely expressing enjoyment of the content without substantive contribution is discouraged. Secondly, engaging with at least two other students is a requirement. For extra credit, you can reply to three or more classmates. Another crucial point is not to procrastinate; you should reply early and often to avoid the possibility of only receiving a maximum of 10 points for last-minute replies.
Following these guidelines demonstrates a thorough engagement with the course material and peers, offering deeper insights or asking thought-provoking questions that can enrich the discussion. This not only helps in securing full participation points but potentially adds extra credit to your overall score.
