The popularity of Chromebook in American schools has made students and teachers loyal users of Google Docs, while creative students fully exploit its functions under the eyes of teachers.Turn it into a popular chat tool。
Students are not allowed to use mobile phones in class, but everyone has Chromebook and everyone uses Google Docs as a collaborative tool. Sometimes they will use its real-time chat function, which will not be turned on by default, and even many teachers do not know the existence of the function. Sometimes they use Google Docs to highlight phrases or words and then comment on them by pop-up boxes: they clone teachers'shared documents and chat in the comments. In the eyes of those who do not look closely, they are taking notes.
If the teacher comes up and looks carefully, they will click the Resolve button and the whole chat line will disappear. Sometimes they create a shared document for themselves and chat line by line. One student said that participants in a chat could use different fonts to identify themselves. At the end of the course, they simply delete the document or all the comments, and nobody knows.
