I am hardly a pentatonic player. I would venture to say, that most people on this site, roughly 90 percent, are pent oriented or the only thing they know. To teach, you have to have some notion of the psychology of whom you are teaching. To reach them, an attempt must be made to explain topics, in "their" POV. Helping them, helps you. Since we're musicians, listening is paramount. A very good teaching method is called the Socratic method. The method always requires a response, of any sort, from the student. The method has changed from the Greeks, and terms have changed, but the methodology has remained reasonably true, constant and consistent.
