Congratulations. You have just been appointed to the Constitutional Convention of 1787.
Having lived under the Articles of Confederation, make your case for continuing with – but perhaps altering – the Articles of Confederation, or for scrapping them entirely and starting over with a new Constitution.
In so doing, you will want to make your case as to why the convention should or should not keep the Articles of Confederation, and not focus on what the new Constitution should contain. In other words, explain to the convention why the Articles of Confederation COULD work, or why they CANNOT work. Do also note that several individuals (indeed, well-respected individuals) made a very substantial case for keeping the Articles (or at least, not making a strong national government).
A brief overview of their arguments can be found here:
Of course, this issue is discussed in both lecture and text, and you should draw on relevant arguments from those sources.
