Although researchers begin to show interest in the problem at the beginning of the 20th century, it is surprising that the results are inconsistent, even to this day. Some researchers attribute the differences to methodological flaws, while others mention conditions that favour academic performance of boys and girls such as an aversion of girls towards physical sciences and this could be responsible for the observed performance variations between the two groups. Iroegbu (2000), who studied secondary school science, found that boys performed significantly better than girls do and posited that there are things in learning process, which affect the understanding of girls and boys differently. Maccoby & Jack line, (1974) found that many studies have traditionally, shown that boys mathematics achievement is superior to that of girls. Although his study is dated, the current study updates his findings by examining if such a view still holds some water today.
