WHAT WE ARE GOING TO LEARN TODAY
This session will dig into the structure of the database, describe some of the relationships between the tables and the Blackboard Learn tools.
• How many faculty are taking advantage of the various tools that are available?
• Which courses have assessments with 'Force Completion' turned on?
• Are courses typically used as content repositories, or are they used more for student collaboration?
OUR CHALLENGE
• Chico State creates a “blank” course shell for every course offered
• We need to determine how many of those course shells are used by faculty
• We also want to know *how* those course shells are used by faculty
COURSE SHELLS USED BY FACULTY

ASSIGNMENTS
• Looking for assignments in COURSE_CONTENTS will lead to inaccurate numbers due to hidden, unused assignments
• Best way I’ve found to identify actual assignments is to start with the gradebook tables:
• GRADEBOOK_MAINGRADEBOOK_GRADE

RUNNING THE QUERY
The query should run on your own system, with a couple caveats:
• You have to use terms to group your courses
• You will need to adjust any dates to reflect the term you are interested in
• You will need to adjust DSKs in some areas to suit your own business rules
FUTURE ENHANCEMENTS
• Using hierarchies should allow us to slice this data in more interesting ways
• This query misses some course content that’s linked only from the course menu (course_toc table)
• I’d like to incorporate student accesses by content into the statistics to more accurately determine content usage
