In addition, it has been proven scientifically that boys and girls develop at different stages of their lives. Co-educational schools have attempted to create equality in the teaching of genders. In both sexes, they both advance in separate points of their childhood. It is said that girls mature more quickly in emotional control, physicality and in their ability to grasp things immediately. However, boys mature in a slower fashion until after puberty where their intelligence is more noticeable along with their physical attributes.
