Is there a tutorial, quick reference guide, or something similar for basic user navigation of the eLearning system?
There are a few resources available to help.
Simple quick video tutorials are available in the "On Demand Learning Center for Students" http://ondemand.blackboard.com/students.htm
A searchable on-line help system is available at "Blackboard Help for Students" http://help-archives.blackboard.com/Blackboard-Learn/9.1/SP09/EN-US/NAHE/Student/index.htm .
There is also a complete video tutorial covering all aspects of using eLearning from Lynda.com (requires CadID) http://www.lynda.com/tutorial/84527?org=uni.edu.
