On demand writing is very stressful. The other day, another colleague and I were asked to respond to an email from a newspaper reporter about the mobile book libraries that we were organizing to help supplement classroom libraries at our school. We had no space for a book room in our two building campus of 1200 kindergarten through sixth grade students. Our solution was to utilize several carts of books at varying levels that teachers could wheel into their hallway or into their classroom to use for both small group instruction and matching readers with books for independent reading. Needless to say, this was and continues to be a huge and very expensive project. The local newspaper wanted to write a piece about the book carts and had requested a response to several questions by the end of the day. My colleague and I were asked to craft this response to the email at 3:00 pm, thirty minutes before dismissal. We knew our audience was the reporter and readers of the local paper, many of whom might be parents of our students. We surmised our purpose was to give the reporter enough specifics and quotes to add to her piece since she had already talked at length to the principal. We had no idea what the angle of her piece was going to be. We also wanted to promote our school. It was extremely hard, especially given the time limit. I plan to share this real life on-demand writing experience with the third graders I’m working with this year.
