Acquisition of third languages in immersion education

[Alison Henry]

I would be grateful if anyone can suggest references to recent work on
the acquisition of a 'third' language by children in an immersion
setting - this is on behalf of a student who is undertaking research on
the acquisition of French as a 'foreign language' by children with L1
English who are attending an Irish immersion school and being taught
French through the medium of Irish, and is interested in finding studies
which have been undertaken in other immersion settings, particularly
work which might not be readily accessible through the usual
bibliographic sources.
