Your first assignment is the introduction to your chapter. Keep in mind that this is the basis for the rest of your chapter. You shouldn't later rewrite your Introduction completely, because you did not know what to write. This assignment already counts for your mark.
The mentioned APA Publishing Manual is not online. However, there is a good overview here
