Another problem is how such a course can be evaluated in general.
Czerniewska (1981) accuses Carter (1980) of judging the course by inappropriate
criteria, those of academic linguistics, and in commenting
(1981, p. 39) on the whole course, says that "the real test is its usefulness to
teachers". In fact, she defines (p. 37) an in-service course in an even
narrower fashion as "one that will lead to improved classroom practice".
The claim that applicability to the classroom teacher in this sense is primary,
is a common type of argument, which I have already discussed. This is only
one test. Others are accuracy, consistency, clarity, interest, academic and
intellectual value. Furthermore, the relation between analysis (e.g. of
discourse) and behaviour (e.g. in classroom interaction) will rarely be
direct.
