Another place where the changes were very bright. School. Soviet schools were quite utilitarian in comparison with modern schools. But there were a lot of them. Even many small or inaccessible villages had their own schools. When I went to rural school in 1980, there were 7 students with me in my class. In the classroom, which was three years older than mine, there were only two girls. The whole class is two people :) It was practically individual training :D In cities, of course, there were also large classes, in some cases up to 30-40 students. Schools were considered a very safe place. Children already in the first class went to school from home independently, sometimes for several kilometers. And parents did not worry that something bad could happen to their child. Fences around schools were purely symbolic. And often absent at all.
After the beginning of perestroika, and by the time of the collapse of the USSR, the situation has changed a lot. In schools, began to appear drug addiction, crime, alcoholism. I already did not find this period, because I graduated from school in 1990. But, of course, I've heard a lot about this period from relatives and friends who studied at school at this time or whose children were studying there. And my mother is a teacher.
Then, education in Russia underwent a major alteration. Schools became much smaller in number, but they became larger. Around the schools appeared fences. At the entrance to the school sits guard. Especially after Beslan, when the Chechens attacked the school, which resulted in the death of more than 300 children. In recent years, schools have undergone serious repairs, re-equipment with the latest equipment. But the main trouble is the very low prestige of teachers. Low salaries of teachers, low social status. This is a very big problem for modern Russia.
Soviet schools looked like this in 1988:
And this is what my rural school looks like today:
Schools look much better today than in the USSR. But here the level of education has become noticeably weaker :-/
