It is usually taken for granted that boys are better than girls in science subjects. A recent study that shows science achievement of males and females separately indicates that this assumption has an empirical basis. Thus the I.E.A. (International Association for the Evaluation of Educational Achievement) study of science education in nineteen countries shows that boys consistently achieve significantly higher than girls in the physical science items at each of the three age levels sampled in every country, and the differences widen with increasing age.peer-reviewe
