I agree that there is a lack of black role models in the classroom I see it in all the schools I teach in.
There is alot written about this in the TES (Times Educational Supplement) and there are also distinctions made between achievement of Black African and Black Carribean boys. But there are schools where achievement is rising especially where the school employs mentors who the boys can relate to and who they may often respect more than the teachers. There is also evidence that where parents are meaningfully engaged in the learning of their sons i.e collaboration - parent - young person - teacher progress is made - St Martin in the Fields school in Brixton is working on this (girls school though !)I know there is a recruitment drive to attract more people from ethnic minorities into London schools. As bad I find the lack of any male role models let alone black role models in primary schools yet nine times out of ten the head of a primary school is male !!
