Ever struggle with students saying that they don’t know what to write? They know they have the story in their head, but they are struggling to get it down on their google doc. We can debate whether or not "writer's block" is real, but that debate won't change the fact that some of your students are struggling to get started and you really, really want/need them to start writing.
Or maybe they know what they want to write, but the typing process is so painfully slow that they get frustrated and quit? While typing skills are important and should be worked on in context, sometimes you just want all of your students to have their writing to work on so that they can start the real learning of revision, receiving feedback, and more revision.
