Hello. Yes, I agree there is currently a gap in schema.org for 
educational courses.

Aaron, thanks for mentioning LRMI (though actually ExercisePlan is from 
elsewhere). Yes that will add properties to schema.org for the 
description of the educational properties of resources. The intention is 
that the properties LRMI comes up[1] with will be added to schema.org 
Creative Works and Events. I'll leave you to decide which best describes 
the courses you deal with :)

So looking at Justin's list (noting that he mentions duration and so 
thinking of it as an event, indeed http://schema.org/EducationEvent ):

For Course Name use name from schema.org/thing
For Course Length use duration from schema.org/Event
For Learning Objective use educationalAlignment from LRMI with an 
alignment type of "teaches"

For Certificate possibly use educationalAlignment from LRMI with 
suitable alignment type

I'm not familiar with CEU values, but it looks like a framework from 
describing the educational credit associated with a course, in which 
case educationalAlignment could be used.

Course author, this could be performer from schema.org/Event (which 
covers presenters), but I think it is odd that there is no Event 
property for a generic "organizer" which would cover some other aspects 
of course author (such as what we mean when we say that something is an 
MIT course). Alternatively you could use the additionalType property to 
bring in properties from schema.org/CreativeWork such as author, 
creator, provider.

Anyway, I suggest it would be interesting to do some work to find out 
how much of the gap in schema.org regarding educational events is can be 
filled using existing properties (including well developed proposals 
such as LRMI), and what new properties or changes would be desirable.
