Twelve months from now I imagine myself doing voluntary work for some publishing organisations as well as developing my own materials for classroom use. I have noticed that, usually, coursebooks are outdated, especially when it comes to the topics discussed. The grammar points also are not always adequately covered. Take for example the case of some or any, according to some coursebooks some is used in positive sentences and any in negatives and questions. This is not the case, however, for request where we can use some.
I think that the best idea for me is to work with some teachers in the teaching centres to develop some materials for different levels and age groups and store these materials in a shared folder in order for all teachers to benefit from them.
I deem it also important for me to do voluntary work for some publishing companies in order to immerse myself with different learners and learning needs and also learn from more experienced materials writers
