Quick user's guide: Each module is broken into a series of topics presented in as a video of a narrated slide-set addressing that topic. Assessment questions are organized using the same set of topic headers. So, open the assessment document, watch each video, and fill in the answers as you go. While we can discuss issues or questions during our weekly tutorial, you are welcome to email me with any questions as you go: [email protected] is the best way to reach me during the spring of 2016.
Note: The videos play well in Quicktime!
