Warren,
Have you tried the reports in the course?
Left side navbar > participants > click on a participant's name > left side navbar click on Activity reports > try Complete report or Outline report.
Do those work for you?
If you know SQL querying (I don't), there a couple of adhoc report plugins that are very powerful, one by Tim Hunt. Don't remember the name of the other. These allow anyone with permission to access the plugin in a course (teacher, etc) to run a query and see the results.
