The methodology employed is a socio-lin some randomly selected urban centers in Cameroon for example, Buea, Bamenda, Kumba, guistic survey of etc.. The results suggest among other things： （1） that Cameroon is a highly multilingual country with over 280 home languages and （2） that while English is the language for Anglophone education, Pidgin English is actually the predominant language and the first language for most Anglophones. Based on these findings, the author proposes Pidgin English as the choice language for early education in Anglophone Cameroon （the southwest and northwest regions）. Pidgin English is the only language which expresses Cameroonian reality. It is spoken by more than 70% of the population. It is the only language that is not associated with a particular tribe, religion, or with a specific colonial government.展开更多
