Here at DyslexiaHelp, we recommend outlining and concept mapping as compensatory pre-writing strategies for students with dyslexia. As you apply these recommendations to your own writing process, be sure to visit visual-literacy.org [1]. Here, you can familiarize yourself with numerous methods of visual representation via the Periodic Table of Visualization Methods [2] (including real-life examples of a story template, learning map, and Venn diagram). These methods are especially helpful for dyslexics who self-identify as visual learners!
