My recommendation would be to add a separate site (usually pretty easy to do ... just follow the typical installation instructions).

Then, you can export your current content into an XML file and import it into the new site.

###A Better Option Create a new site on WordPress.com and import your content there. This has the benefit of being easier to set up, allows you to add other authors, and doesn't require you to keep hosting it in the future.

It also means you can keep your class notes online for future classes (and give ownership of the site and content to others in the future).
