What is the method for congregational prayer between a female teacher and her students at school?

It is permissible for a female teacher to lead her female students in prayer, and she should stand in their midst so that they may learn and benefit from her prayer. However, if the students are males and females, the female teacher's imamate is valid only for the females, and the prayer of the males is invalidated. If there is a discerning male child among the students, his imamate is valid for the female teacher and the rest of the students, both males and females, according to the preponderant opinion. A woman stands behind the rows of males, even if they are young.
