I spent two weeks with a summer camp caving/canoeing SIG of 11-17 year olds. Part of this involved teaching map reading and orienteering. I had both cave and topo maps along, and they duly looked at them, but it really didn't sink in until we visited a cave on a well-beaten loop trail. This trail has two cave entrances on it. They disregarded the topo and ended up at the wrong cave. I let them do so. We had to get the key to the cave being visited,and they were confused when we got there and no gate existed. I let them figure it out, and they eventually came to the conclusion that they should have looked at the map before running off down the trail.
Once in cave, they requested the cave map, and followed along, esp. after I again let them go down a 'wrong' passage where they had to crawl, avoiding the 30 ft high dry walking passage.
