I think bsl should be a language option for gcse/A level.
However, I think it would be great for Makaton to be used and taught more widely in preschools and primary schools.
Whilst Makaton takes many if it's signs from whole word BSL, there are a lot of differences, and BSL is a language in it's own right, whereas Makaton is used with and to support speech. Because it is very simple, and uses whole word with speech, it is useful for children and adults with learning disabilities, people who have suffered strokes, children with English as a second language and it is also used in some old people's homes here, to support spoken word.
Adsy, my 4.8 year old ds is non verbal and uses Makaton as his main form of communication - it is used by all the teachers and TAs in his resource base, and his ms teacher have been sent on a course. The carol service for the whole school have key word signing, as do the assemblies. We use Makaton at the preschool I help at, which is mainstream.
