eagerness must be accompanied by imagination which leads the teacher to
put himself in the place of the pupil. This means that the teacher has
to take facts and wrestle with them until they are lodged safely and
permanently in the minds of the pupils. The teacher must see the things
that confuse the pupils and after seeing these difficulties must clear
them away. There is always the temptation for the teacher to blame
failure on the dullness of pupils rather than to ask whether the
teaching has been adjusted to the conditions of the pupil’s mind.
