What is the difference between a modern school and the old school?

In our time, it cannot be argued that every former school can be called modern. First of all, this applies to rural schools. But it is impossible to say about all city schools that they meet modern requirements. A modern school should be in good repair, equipped with all the necessary books and equipment, the necessary furniture, equipped with computers. When the schools have everything necessary for a full-fledged educational process, then we will say that this school is modern.
