My first section of Intro to Art for the semester had problems regarding students creating their own Blogger pages. 6 of the 20 students in my class were not able to create new blogs from the computers in our classroom lab. These students were able to do the following: they signed-in to their Google accounts, selected "Create New Blog", and input a page name and url. On the next page, when they were asked to provide a phone number to be texted a verification code, the code or page was "invalid". I had these students sign-out and try again at another computer with no success. After a few attempts, Google also said that their phone numbers were locked out of any future attempts.
Does anyone know what the problem may be, or how to avoid this in the future? Could this have anything to do with the fact that these students did not have Google accounts before today?
