1. not sure specifically what
   not sure specifically what you are teaching but try researching gamification. You should find tons of material about it.

2. The start is to ask them what
   The start is to ask them what they feel they could gain from the subject you are covering, that will generate real motivation to learn more.
   Clearly identify what you want the participants to experience from each section of training and develop interactive exercises wherever possible, e.g. if it is an IT subject like finding a file – see how many different routes they can find to the required file? This is gamification but very simple and would open up possibilities fort them to learn more about the operating system, by accident!
