This clever freshman writing student created a project in Texture, which is designed for branching narratives (such as the Choose Your Own Adventure stories). In the next few screens, he put up nodes showing older and more recent writing samples, asked me to choose which one showed the better writing technique, and gave me feedback on my answers. Very clever!
My father once told me about a paper he was grading years ago; the student inserted a sentence midway through that said, “If you’re actually reading this, please check here.” My father did, and saw the student’s face turn red when he handed the papers back. I wonder if he’s related to your student!
