Colin Baker who is the Professor of Education at Bangor University, is the author of a number of books including : A Parent and Teachers Guide to Bilingualism, Encyclopedia of Bilingualism and Bilingual Education and B is for Papillon, Biliteracy in the home. Although an academic, Colin Baker is clearly committed to practical aspects of how to make bilingualism work in the family and at school.
Colin set out 10 advantages of bilingualism he indicated that it takes quite some energy, commitment and perseverance to raise children bilingually and that reminding yourself of the advantages when things don't seem to be going well can help you to keep going. The balance of scientific evidence shows that each of the 10 advantages below is true with the exception of no 4, which has not been researched enough. There is more detail on each of these points in his book "A Parent and Teachers Guide to Bilingualism".
Communication advantages
- Wider communication bilinguals can communicate with extended family, community, international links. Bilinguals may also be bridge builders between different language communities.
- Biliteracy gives knowledge of different world views and values
Cultural advantages
- Broader enculturation, "deep multiculturalism" and two language worlds of experience; two windows on the world !
- Greater tolerance and less racism? It seems likely that bilinguals would be more tolerant of difference and diversity and less likely to be racist but this is yet to be scientifically tested.
