6. Teaching children in English is fine if that is what they speak at home and their parents are fluent in it. But that is not the case in most public and low-cost private schools. Children are taught in a language they don't understand by teachers whose English is poor. The children learn neither English nor anything else.
7. Research demonstrates that children learn more when they are taught in their mother tongue than they do when 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. Parents might say that the point is to prepare children for the workplace, and that a grasp of English is more use than sums or history. Yet by year five the children taught in Kom outperformed English-medium children even in English. Perhaps this is because they gain a better grasp of the mechanics of reading and writing when they are learning the skills in a language they understand.
8. English should be an important subject at school, but not necessarily the language of instruction. Unless they are confident of the standard of English on offer, parents should choose mother-tongue education. Rather than switching to English-medium teaching, governments fearful of losing custom to the private sector should look at the many possible ways of improving public schools—limiting the power of obstructive teachers' unions, say, or handing them over to private-sector managers and developing good curriculums and so on.
9. Pakistani Punjab has decided to end the English experiment; Uganda has introduced mother-tongue instruction in 12 different languages in the first four years of schooling. More should follow. After all, it was a good education in his mother tongue, rather than in the classics then favoured by the British aristocracy, that won Churchill the Nobel prize for literature.
