At first, I think that “education” is not unique. In my head, 2 possible meanings are floating around.
At first, there is the entertainment we all know from TV, those “entertainers” that try to be fun and mostly make me get some headphones so I wont have to hear them anymore.
However, since I have learned some stuff about “entertaining games”, there is another - vastly different - form of entertainment floating in my head.
In a game, you have to create some form of motivation by entertaining the player. If you don’t motivate your player, he will close the game and go back to play World of Warcraft. But now, we have to look out. Most motivation in a game does NOT result from some lame jokes (or even some good ones), but by applying to very basic instincts.
You kill a monster? Hooray. My game will let 2 stars fly around, bounce around a bit and disappear. You killed a boss? Hooray. My game creates some big explosion and makes the screen shake and whatever.
This form of motivation and entertainment is far more universal than the first one, because it applies to your very basic instincts. Things flash! Things move! Things flashing and moving are great!
So, lets take this to our current topic:
I guess you can apply the same here. Trying to entertain some guys from the university with lame jokes during a presentation will fail. fail bad. (I guess this fails with most audiences.)
However, I think that the second form of motivation and entertainment should work as well.
For example, you could just encircle a problem with some red border, because this is a problem, and a problem is dangerous (and red == danger). However, don’t create a whole slide with a bright red background, because this just hurts in the eyes.
Generalizing this, you should be able to use colors to make text (if you really need that text!) more “entertaining”, or little gimmicks (for example, a really nice presentation by Audrey Tang used smileys a lot. Depending on the audience, you might not want a whole slide consist of just a frowning smiley, but still, I dont think it will enrage someone if your problem (encircled in red! ) is followed by some sad smiley-face.)
So, I guess, you are right to a certain extend. You have to entertain the audience on a certain level, however, one has to choose that level and the tools of entertainment carefully.
