I used to yell a lot. Particularly in the last week of rehearsals, I would yell. I wouldn't say I screamed, and I never, ever cussed. But I got upset, and I yelled.
The kids? They laughed.
There's something about me angry that people find funny. I've been told I have kind of a George Costanza way when I get angry. I thought I was convincing. I did marching band staff for years, and I yelled a lot. (Granted, most of that yelling was simply to be heard.) But when I yelled in an environment where the kids were not at attention, they laughed. Worse, they pandered to me. "Okay, Mr. Cosper, settle down, don't have a heart attack, It'll be okay."
I took a new approach when I took my current teaching job. Having heard Tony Dungy on Focus on the Family radio discuss his own approach to leadership - to talk, to correct, but never to yell, especially in anger - I resolved I would not yell. The occasional call for quiet still happens; when thirty people in a big auditorium are jabbering and you don't have a megaphone, you have to get their attention. But when action was needed, I resolved not to yell.
Four days before opening night was my biggest test. The kids at school are all very busy, and many frequently miss rehearsals for athletics and other events. One scene in the play was suffering terribly because of absences, and the actors were in the mood to play. We stopped, and we talked. I didn't yell; I simply told them the scene was a disaster waiting to happen. It was bad, and had always been bad. And they all needed to work together to fix it.
That was all it took. The scene got better. I didn't have to scream. All I had to do was make it clear they had to do the work.
Happy to say what works on the football field also works in the theater. As Christians we can set an example and be a light, not just in Christian settings but beyond. I've seen directors rail and scream and swear, in high school and in the professional realm. It gets the job done... but it's terribly unattractive. I think Coach Dungy's kinder gentler approach not only does the same job, but it would definitely leave a more lasting impact for the kingdom.
