In sixth grade we got to go use the computer in the teacher's lounge to print out a topic from encarta. At secondary school we had to sign a set of rules for using the computer lab. At uni we had a proper user agreement with the IT department. Mostly because we had multiuser systems, e-mail and webhosting at our disposal.
My kid is still a few years from starting school. I'm hesitant to sign any Google EULA on her behalf.
