How about a much smaller change that is much easier to do
(specifically, avoiding maintenance of a textbook->language alist):
when the current select-your-language dialog comes up, don't have any
default chosen, and disable the Next button until something is
clicked?

(Except for maintenance of yet another alist, there is also a problem
with people who provide their own language levels: they will have to
either tell the students to use some book name that is close to what
they use, or tell them to not choose any book and on the second screen
choose some language, but then deal with people who will complain
about no second screen because they just happened to click on
something on the first etc etc etc etc etc etc etc etc.)
