Educating a girl means Educating the whole family. it takes place in the following ways:-
Step 1)  When a girl attends school she will first learn the concept herself.
Step 2) She will help her brothers or sisters in their studies too
Step 3) she will help her classmates to make them understand             the concepts too                               (like I do, everyday)
Step 4) If her parents or grandparents do not anything she explain to them too.
Step 5) After she is married she will explain what she knows to her children too.

In this way she can educate everyone, but she is not educated herself she can't spread the knowledge to anyone at all.
