Post-Reading Assignments (Artsy-Fartsy Stuff)
If you were to assign your students to take apart a vacuum cleaner and look at it, and they do so, they may learn a little bit about how vacuum cleaners work - although they haven't necessarily demonstrated so by this disassembly.
You could ask them to put it back together, and if they're able to do so and it still vacuums, they have perhaps learned slightly more - and have at least demonstrated the ability to echo the existing construction of the machine in a mildly useful way.
But if they are able to take apart a vacuum cleaner, analyze it, pull a few parts from other items around the house, and use those parts to construct a functioning hovercraft - one which they then ride down the street with their Back To The Future goggles on - well, they have learned and demonstrated a rather impressive comprehension of the physical properties and functioning parts of vacuums and a few other things as well. They have, as we love to say in educational parlance, "demonstrated mastery."
Besides, just between you and me... ... sometimes we like to do artsy fartsy stuff and hang it on the wall for parents and principals to see. The most unlikely students sometimes flourish with this stuff, and as much as we all love a good 2000-word-typed-and-double-spaced-with-separate-citations-pages essay, we suspect there's a pedagogical time and place for something less formal and more aimed at creative content-crunching.
The few below are some personal favorites of mine, but please feel free to share if you have others to post. I honestly don't remember which parts are original with me - I know I've at least altered and reworked them, but I don't think any of them were mine from scratch. I assume if you use them they'll evolve for you as well - that's how this stuff seems to work.
RAFTing Through History - Informal writing in various formats to demonstrate understanding of content. Role, Audience, Format, Topic.
Know-It-Ry - Boring information makes great poetry, especially if the poetry is already written and all we have to do is replace the words with those saying what we want.
ABC Summaries - Summarize this article in 26 sentences which must read like a normal page of informational writing, but which just happen to be in alphabetical order.
Quick-Writes (They Do Everything) - OK, Quick-Writes aren't actually artsy-fartsy, but they are post-reading. Er... usually. Really, though, they do EVERYTHING! Hence the title.
