I don't use this for everyone, but especially with rhythmically insecure students, it seems to really help. I have students that if they try to learn something on their own, the rhythm is waaaay distorted when they come play it for me. The verbal/aural association of the words helps them a lot. And sometimes if they can remember the words, they will implement it on their own. Even for adult students, it seems to be a good way to get them to feel the rhythm. Granted it doesn't help teach meter per se, but at least the rhythm is steady. In fact just today I was working with a student on a Chopin piece, and this one measure was strawberry, strawberry, university, university, pear. To get a beat of 3, 3, 5, 5, and end on 1. It worked. Another student in a much lower level was playing a little Handel piece, and the rhythm was the same for the whole piece. Dotted eigth/sixteenth, two sixteenths/eigth, and then two eighths. So the words: I - - like buttery popcorn, for the entire piece. Worked for her too. She is probably my most rhythmically insecure, BUT she is getting much better.
