The British Council has a series of seminars running for those who teach learners with special needs.
Sessions cover teaching visually impaired learners, learners with speech difficulties, and more general sessions on dealing with learners with other learning difficulties.
The sessions run from Monday December 2nd to Friday the 6th. Each session runs twice during the day for those who have to work!
