Hi Scott! Hope this isn't too late to be useful, was just scrolling through older posts...
It's so awesome that you're getting a chance to share all the knowledge you have! You said you don't like lecturing so I had some ideas on this topic that I've seen work (though they might depend on the time you have). Pretty much all the training I've seen has involved knowing your own type of personality (that's half the battle)!
- situational role-playing. I liked it better when there was only one example to watch (as opposed to splitting the class into pairs) because we spent some time afterward talking about it and it made principles much more concrete. I've seen this done with both students as both people AND also with the facilitator as one of the people (great when it's about working with "difficult" personalities).
- self-evaluation quiz: half of learning to work with others is understanding how you work, so people get a better understanding of themselves, and a framework for understanding others' personality types. Discussion about people's relationships with their own type, and about getting to know the various types.
- exercises: done after everyone in the class knows their "type". Class is split into teams with type distribution and have a certain amount of time to accomplish a creative task. Discussion about specific interactions with different types of people, knowing the other person's type might explain some of the conflicts that arose, etc.
