I tried this with my kindergarteners this year, but was unsuccessful. But I know that it works with older kids and it would have eventually worked with my Kindergarteners, but I guess I dropped the ball on it.
We tried it at a workshop I attended last summer and its really neat the way it works. It definitely looks like chaos to the untrained WBT eye, but by the time you introduce this, I'm sure you would have used a lot of the other WBT techniques successfully. I like doing the 'Yada Yada' with my students and they get really loud for a moment, but if a 'passer by' stays and watching it from beginning to end, they understand your reasoning. And why not? It's so much fun for the students!
I'd probably start with other techniques and introduce this after the first few weeks. what I was able to do successfully while my students passed out papers is recite rules for the class, math, spelling, skip counting, etc. Even though it's kind of the same thing, they worked better with this, than the clapping and cheering.
Good luck,
