Hi Roi,

We developed something a long time ago for a client on Moodle 1.9 that did this.  From memory we basically created a custom course format that allowed the admin to select a parent course in the settings.  The contents of that parent course were then displayed in the top section of the child course and the rest of the course page allowed activities to be added like a normal topics course format.  We did this so long ago and the client has left us now that we don't have the code any more.

Some things to look out for if you are developing this:

You need to enrol the learners on the parent course otherwise they can't access the activities and resources and track progress.  We used metacourse functionality to give learners access to the content of the parent course.

Course completion tracking won't work without extra development

Reporting will probably need changing as the activities are in different courses

Hope that helps

Regards

David
