teaching sources on two-dimensionalism?

In Fall I'm teaching my senior/graduate class on Philosophy of Language. Two-thirds of the semester will be spent going over Alexander Miller's generally* excellent Philosophy of Language book.

For the final third, I'd like to do something on two-dimensional semantics, if that's possible for students who have a general textbook like Miller's under their belt. Assuming it is, can anyone recommend a readable introduction suitable for smart upper-level undergraduates?

It's one of the hardest and most interesting issues in the contemporary philosophy of language, and there are so many different ways into it (e.g. logics with actuality operators, Stalnaker's work that has been picked up by linguists, Chalmers' contributions to metaphysics) that serve different explanatory demands. . . I'd love it if there were a good intro that's easier for students than Laura Schroeter's Stanford Encyclopedia piece (which is a wonderful resource).

Any advice for how to pitch this in one-third of a semester to people who've been through Miller's book would be deeply appreciated. If it's an impossible task, advice to that effect would also be helpful.

[Notes:

*In my experience Miller's teaches the best and covers the most relevant background material for students who want to go further in analytic philosophy. Miller's ability to clearly explain difficult material and boil important arguments down to their basics is unparalleled. It's only flaw is that it's about forty years behind linguistically with respect to the syntax-semantics interface, but since every** other philosophy of language book is also weird in the same respect, this is immaterial.

**This includes textbooks by Lycan, Soams, Devitt/Stereln, Morris as well as the usual anthologies, e.g. Martinich/Sosa, Ludlow, and Hale/Wright. I haven't read Lepore/Smith yet; it actually looks substantially better than the others in this regard, though Lepore's misleading article on Montague Semantics (focusing on possible worlds rather than on the syntax-semantics interface) in Ludlow gives me pause, as does the equally misleading article on Pustejovsky that he did with Fodor. This being said, the lineup is pretty amazing and when I have the cash I'm going to order it and maybe teach a class around it next year.]
