You may want to consider using this class to get an education - in education - of self and others. Two possibilites present themselves.

As mentioned by others above, offer (humbly) to become a behind the scenes 'helper', perhaps as someone to talk over the material for each class ahead of time. (You could look at this as training for being a beta tester, if you want an 'industry' justification.) Very likely you will get a glimpse at the process of putting together class outlines for teaching - and learning.

Another more intriguing possibility is offering to teach a topic or class yourself. My wife is doing this for one of her students (undergrad) who was already doing a research paper on a topic that fits in with the course plan. The student will get a double bonus in that the material will be much better reviewed (my wife has multiple meetings scheduled) and the student will get the experience of teaching.

I wish I'd done some of this in one DB class I took that was floundering. When the professor later ended up in one of _my_ classes, he gave suggestions none (and a bad evaluation to boot!)
