Which is what the Tennessee "model" is based on. For those who have any interest in getting into the nitty gritty of this (which it looks like Barone doesn't want to do), The Wisconsin Center for Education Research hosted a conference last spring on this topic, and there's more than enough research in the papers to raise more questions than answer them.

Invoking it in this context doesn't make even metaphorical sense. No, that’s not Zeno’s Paradox. Zeno wrote about distance, which as far as Zeno knew, was infinitely divisible.
