I have added the descriptions for the second and third papers, and changed the due date for the second paper to the week after reading week. I would extend the deadline for the third paper as well but am unable as it is already due on the final day of class. But as you now have the topic, you don’t need to wait to get started on it.
We can talk more about both assignments in class. As with the first paper, you will have the option to rewrite the second paper and I will average the two grades. I encourage you to blog about the process as you work on these, and to share ideas and even drafts on your blogs, if you like.
