I actually used the dinger to inspire my writers. For example, we're currently working on persuasive letters. Even though I'd modeled and taught a handful of lessons on backing up their opinions with details, which typically isn't an issue with my writers, the majority of this year's class wasn't embracing the idea in their daily writing. Somewhat out of desperation, I brought out the dinger one day and made quite the hullabaloo about it during my mini-lesson on using details. Of course, when they heard what the dinger could do and that they could be the ones to create that sound, their little eyes lit up.
Off they went to write, and off I went to circulate the room, looking for writers who were using details to back up their opinions. Each time I found one (and I found many that day), the child got to ding the dinger while I made a quick announcement about what that writer had just done. My goal was to catch as many of them trying the strategy as possible, and I did just that.
Yes, it's a little noisy. Yes, it interrupts the writers, Neither is ideal for the everyday writing workshop experience. But, it motivates writers who won't budge and need a push in the right direction. A little noise and interruption a few times a year is worth it when my writers take on the challenge and get over that hump in their way. DING!
