One way you can publish your students' non-fiction writing is to have them create a fake newspaper clipping. I would recommend having that they first type it in a Word/Google Document, just in case they can't finish it in one sitting. Then, all they have to do is go to the site linked above, create a fake newspaper name, date, and headline, and copy and paste their text from the Word/Google Document into the story section on the site. Once the clipping is generated, they can right click on the image and save it to their documents. Students could submit their completed clipping with you via Canvas or a shared Google Slide.
