Needs do vary across the regions.
In urban centres, good knowledge of the language and teaching methods are also fundamentally important. However, training in interculturalism and cultural or multicultural knowledge is important. We often suggest that teachers stimulate students' curiosity about other languages. If someone speaks Arabic or Japanese, why not make presentations on the subject and talk about those languages. Languages are not big ferocious monsters. The idea is really to talk about that and play with it. There are a lot of inclusion and diversity problems that are part of the broader issue in the major urban centres.
