A、If kids did not like school, real learning would not take place. B、If not forced to go to school, kids would be out in the str

（19）Some people say if kids didn’t have to go to school, they’d all be out in the streets. My reply is no. They wouldn’t. First, even if schools stayed just the way they are, children would spend at least some time there. Because that’s where they would be likely to find friends. Second, schools wouldn’t stay the way they are. They’d get better. Because we would have to start making them what they ought to be right now. （20）Last, if we stirred up our brains and gave children a little help, those who did not want to go to school, could find other things to do—things many children now do during their holidays.
   （21）There is something easier we could do. We need to get kids out of the school buildings, give them more chance to learn about the world at first hand. In Philadelphia and Portland Oregon, plans are being drawn up for public schools that won’t have any school buildings at all. That will take the students out into the city and help them to use it and its people as a resource. In other words, students, perhaps in groups, perhaps independently, will go to libraries, museums, exhibitions, courtrooms, radio and TV stations, meetings, businesses and laboratories to learn about their world and society at first hand. A small private school in Washington is already doing this. It makes sense. We need more of it.
