Do you agree with the saying that male teachers are better than female teachers? Why?

Male or female it depends on the ability of a person to teach better or not. a male teacher may be good or bad and likewise female teacher good or bad. In some societies male teachers may be performing better than female teachers due to more free access they get for everything. In some other societies female and male are equally good when same opportunites and free access given. 

NO.

BOTH ARE TALENTED.

BOTH CAN CONTRIBUTE ACCORDING TO THE SOCIO-CULTURAL ENVIRONMENT OF THE COUNTRY WHERE THEY WORK  

Nay. Both are equally good and decent.
