This is not permissible and there is no jumaah for you for doing this.

I work in an Islamic School where some teachers take turn to give the Jum’uah Khubah. I ask the children I teach to pay attention because there will be a quiz the following Monday. I then make some notes as the Khatib is speaking so that I can refer back to them during the quiz. Is this permissible? I don’t find that this causes me to be unable to listen attentively
