I received an interesting question the other day: If you were running a minyan for young teens (12-15), how would you handle the reading of Koheles? Would you force them to deal with the 30-minute interlude, holding their Stone chumashim and likely staring off into space for long stretches, or would you find some creative way to handle this, perhaps abbreviating the reading?
[The following paragraph was accidentally omitted from the original post, and added several hours later:] Our Sages registered the same concern regarding the Book of Esther and the Haggadah, despite their gripping stories, and solved the problem by adding read-alongs to Esther (Mishneh Berurah 689:16) and distribution of toys prior to the Haggadah. (Pesachim 108b)
In general, I believe in the idea of abbreviating in certain parts of davening on a temporary basis, for the sake of building kavvanah. However, I have a hard time with the idea of abbreviating Koheles; it's only read once each year, and so the kids won't end up hearing the whole thing. Also, they are a tzibbur, and a tzibbur should read Koheles; this is not the same as having individuals skip certain paragraphs of Tehillim in pesukei d'zimra.
Another option might be to interrupt the reading with questions about the text, but I'm not clear on how that would work here. Even if the kids could be drawn into real discussion, the trade-off would be elongating an already-too-long reading.
Another option: I've been told that there was a minhag in certain communities, going back centuries, to split up Koheles between the opening and closing days of Yom Tov. This might be worthwhile.
For the most fun, perhaps there could be a "drinking game" variation for Koheles. Postpone the reading until after musaf, make kiddush, and then distribute bows of corn chips, pretzels, etc. Every time you hear "hevel", pop a pretzel. Every time you hear "ra", have a corn chip. Etc. The kids would read it, and the dentists would love you...
What would you do?
