For that reason the pre-service training should include:
- 3 or 4 periods of real teaching in different schools throughout the whole degree,
- with a good pre-service tutor in the college as well as in the schools,
- and a mandatory pre-service period in an English speaking school or an Erasmus.
In this sense, colleges should facilitate international exchanges (Socrates, Leonardo ,...) and provide some subjects taught in English during the degree, to achieve a very good command of language, especially oral (level A2 or A1 CEFR *), without forgetting the training on methodology and on English language in all specialties of teaching.
I like this example of small project done by future teachers as part of their training at the URV (Universitat Rovira i Virgili in Tarragona). It is a story called The Dummy Panda and it is made with some ICT (and non ICT!) resources and, above all, it takes into consideration some of the above mentioned issues on pre-service training.
I think it is amazing and it can give some interesting clues and ideas to do wonderful things in your classes.
