Google Drive allows the user to work in offline mode so students can complete classwork at home, even without internet access. Files are saved locally to the chromebook, then automatically updated the next time a wireless connection is detected. So a student can start a project at school and finish it at home, even without an Internet connection. When the student returns to school the next day, anything he or she worked on at home will be automatically updated to their Google Drive. Offline mode must be enabled while connected to the internet before students can use it. In offline mode, students can edit their documents and presentations. Spreadsheets, however, are view-only for now.
