Actually, that might be misunderstood. My aim is not to create a
teaching.org file but many org-files, one for each topic. I totally agree a
single org-mode file for an entire course would be really fast difficult to
maintain.
A complete course might consist of many org-files. Splitting the entire
lecture in a similar way like an ordinary table of content.
However, I would love to keep all infos of a certain topic within a single
org-mode file together. Slides, lecture notes, exam questions, exercises,
organisation, TODOs, ideas, maybe code, etc.

GIT will be definitely part of my toolchain independent of the usage of
org-mode.

Actually, that is exactly what I am trying to figure out at the moment. How
to generate a entire script or lecture slides from different org-mode files
which contain not only one sort buy many different sorts of information.

Thanks for the input, I guess  we are more on the the same path rather then
contrary. ;)
