The interventions to try and counteract the misconception at
higher levels (where it is still present) need to be based on the
provision of extensive documentation accompanied by
technically unquestionable analysis; their discussion would go
beyond the scope of the present paper, which focuses on the
pedagogical aspects and the design of pedagogical options;
however, they can largely be based on thought-threads
analogous to those that will be outlined here for pedagogical
interventions, viewing them from the point of view of general
issues like the relationships between language and knowledge
and of practical issues like the obstacles posed by language related
difficulties to students’ performance in all science and
engineering fields.
