Here are my two cents:
The author makes a keen accounting of some rabbinical responses to the "problem" with disinterested teens and tefilla and reflect spectrum of reactions. I appreciate that he is trying to treat the symptoms of this problem and the greater illness - that some kids don't want to come to daven. The last two paragraphs are as honest as you get on the topic of tefilla.
In a recent issue of Jewish Action (Summer 2011), R. Jay Goldmintz writes about the problem in the Modern Orthodox community of teens who don’t, or don’t want to, attend shul on Shabbos (link). R. Goldmintz offers a few suggestions on how to remedy the situation, which I sum up as: 1) force them to go to shul, 2) use walking to shul as a bonding opportunity, 3) model proper prayer.
