     Boys' English grades are up to a tenth worse when high numbers of girls are in the class with them, though

girls' grades are unaffected. Boys do worse in English when there are girls in their class, researchers will say

today, contradicting the widely held belief that girls are always a good influence on boys in school.

     Boys do best with "as few girls as possible" in English lessons at primary and secondary school, Steven

Proud, a research student at Bristol University, will tell the Royal Economic Society's conference. But when it

comes to maths and science, both boys and girls at primary school achieve up to a tenth of a grade more when

there is a high proportion (比率) of girls in the class, Proud found.

     Proud tracked boys' and girls' test results at the ages of 7, 11, 14 and 16 in 16,000 schools in England

between 2002 and 2004 for his PhD. Boys consistently perform up to a tenth of a grade worse when they study

English with high numbers of girls as opposed to few or no girls, Proud found. The more girls there are in an

English class, the worse boys perform. This is particularly the case in primary schools, he discovered.

     Proud said boys may do worse in English when there is a high proportion of girls in their class because they

realize that the girls are better than them. It could also be that teachers use teaching styles more appropriate to

girls when there are more girls than boys in the class. Both genders perform better in maths and science at

primary school when there are more girls in the class because boys tend to disrupt the class more, he said.

     Professor Alan Smithers, director of the Centre for Education and Employment Research at the University

of Buckingham, said girls started school with slightly better verbal skills, while boys started with a slightly

greater aptitude for maths.
