A class notebook has a section called Welcome, which is automatically created. Sections can be created to help organize content for teachers and students. Teachers can create sections anywhere in a Class Notebook. This includes creating sections within student notebooks. Students are limited to creating sections in their own notebook and in the Collaboration Space notebook.
