We use the orienteering compasses where you look in the mirror and line up the two north arrows.

He doesn't seem to get the idea at all. The problem is really less the not getting, he seemed to understand it better after I made him take every baring we came across, and more the not even trying to use the compass.

Of course, the real problem is the PMs not allotting time for training and being upset when the people on their first day can't work as fast as someone who's been doing this for months or years.
