Teaching children in English is fine if that is what they speak at home and their parentsare fluent in it. But that isnot the casein most public and low-cost private schools. Children are taught in a language they don’t understand by teachers whoseEnglish is poor. The children learn neither English nor anything else.
如果孩子们在家说的也是英文，并且他们父母的英语也很流利，那用英语教学是可以接受的。但在大多数公立学校和收费低廉的私立学校，情况并非如此。在那些地方，孩子们在一个他们听不懂的语言环境中接受教育，而授课的老师本身并不擅长英文。孩子们既学不到英语，也学不到其他东西。

Researchdemonstratesthat childrenlearn morewhen they are taught in their mother tonguethan they dowhen they are taught in any other language. In a study of children in the first three years in 12 schools in Cameroon,those taught in Kom did better than those taught in English in all subjects.
研究证实，儿童在接受母语教学时，学到的知识比在接受其他语言教学时更多。一项研究调查了 12 所学校内的喀麦隆儿童，观察他们在入学前三年的表现，发现比起那些接受英语教学的孩子，接受科姆语教学的孩子在所有科目上的表现都更好。
English should be an important subject at school,butnot necessarilythelanguage of instruction. Rather than switching toEnglish-medium teaching,governments fearful of losingcustomto the private sector shouldlook at the many possible ways of improving public schools.
英语应该是学校中一门重要的学科，但不一定得是教学语言。那些担心生源流向私立学校的政府，应该多考虑一些改进公立学校的合理方案，而不是将授课语言改成英文。
