again, a little free, but it might serve your purpose.

One of those popular, slim young teachers who can make pupils listen.

'Mester Puk' was a cartoon figure in a long shirt or smock, who might strike young readers as slightly feminine in spite of the title 'Mester'.

Spellbound
It occurred to me that you could perhaps say something like:
Miss N.N. was a puckish person who could hold a class spellbound.

In times when schools had very few resources other than 'chalk and talk', schoolteachers who could tell a good story were loved and remembered long afterwards.

'Fortællingen' - especially in history and cultural subjects - was the core of the teaching.

Fortælling er en gennemgående metode, som anvendes i enhver hensigtsmæssig sammenhæng, da den dels taler til og udvikler børnenes fantasi dels evner at etablere mødet mellem børnene
