(Okay, so that's something right there I didn't know - I had no idea that Flickr has a blog. It would definitely be worthwhile to read this periodically to find out what cool things people are doing on Flickr.)
Anyway, this blog entry was about how a woman named Kate and her boyfriend had figured out how to make cupcakes that look like cheeseburgers and furthermore, they had put together step-by-step instructions with photographs on how to do it in a slideshow on Flickr.
(No - this is - but the cheeseburger cupcakes are still pretty spectacular.)
Next, the idea of using a Flicker slideshow to put together a set of instructions seems like a very powerful tool for the classroom. One immediate use that springs to mind is that a teacher could put together step-by-step instructions for his or her students, but even more intriguing is the idea of students putting together the instructions. One area of student Literacy that is very challenging to a lot of teachers is non-fiction. Children will buy into reading and writing narratives pretty readily, but getting them to invest themselves something less plot-driven can be quite a bit more difficult. "How-To" writing is often specified in school or state curricula.
Having a class of younger students break down a complex task into individual steps would be valuable in and of itself, but then letting each student or team of students take and edit pictures, then post them with written instructions could be really engaging.
This would also address the goal that many schools have of getting students to write for a larger audience. It might also be a good way to get reluctant writers more engaged - I'm imagining a not-very-academic boy putting together a step-by-step explanation of how he gaps the spark plugs on his snowmobile or eats a hot slice of pizza before his brothers can get their hands on it.
This would also be a good way to document a Science, Health, Art or Phys-Ed project.
I'm also thinking it would be a creative way of meeting the requirements in some students' IEPs.
Plus - you'd have the possibility of cupcakes that look like cheeseburgers!
