What to do? I created a first day Welcome to Your Chromebook video for both teachers and students. This video begins with taking the students to the teacher's website. There the students will find a form to fill out with their school email address. The teacher will use the email addresses to create their Google Drive file management system, a view folder to share documents/presentations.
On the student side, they bookmark the teacher's website and name it accordingly. The students will then create a folder in their Google Drive account and share that folder with the teacher, giving the teacher editing rights. This folder will serve as their "dropbox" for all papers, presentations or whatever else they create using the Google suite of apps. But assuming students understand what a dropbox is may be overstepping their knowledge. Teachers now need to demonstrate how to use the newly created dropbox.
The final step is to make sure the students and teacher have created their class folders with the view folder and the student dropbox folder. From the teacher side, all of the students' shared folders will be organized into a class folder. At this same time, the students will put the folder the teacher shared with them and their student dropbox folder into one class folder.
