Classroom Authors uses four easy steps to publish an e-book or a printed book: writing, editing, proofing, and publishing. Teachers create an account and a project. Have students join the project with a code. Every student with the project code will have a chapter to create. Student accounts require email, but they can use a parent email address or an "+" extension of the teacher's email address, for instance, myemail+studentname@myschool.org. All students invited to the project can be working on their section, on multiple computers, at one time. Adding content is as easy as using a word processing program and uploading images to the gallery. Drag and drop the images into the chapter. Students can view the entire book, but only edit their own chapter. Teachers have complete control over editing, style and leaving comments. There are default templates so the books created are professional looking. Customize to give the book your own look. Classroom Authors is not only a vehicle for publishing; this tool will fulfill the Common Core Standard requirements for using technology for collaborating and writing across the curriculum. The best part of this site: it is EASY to use! Classroom Authors uses ePub to format e-books and offers one free printed book for each published project that has 10 or more students collaborating. Beyond that, there is a cost for printed books. E-books are FREE.
