Hello abla, actually I have done some research concerning how americans and Israelis spend their vacations.
It's not like I would have expected that they use it to teach their children something, on the contrary, they usually use it for playing and relaxing.
The most important factor that determines how they spend thier vacations is "money" so the rich ppl can travel to some place for about 2 weeks and visit the museums of that country and learn about its culture. But in the less rich families, the parents must work during vacations and the children are let to relax and have fun.
The school vacations in Isreal are same as everywhere esle in the world and their way of life is most similar to europian people.
In the US, the students with very low or failing grades are foreced to attend summer school.
In the US, colleges are not free and are usually costly,so not many people go to college, and those who do have to work while studying.However, in Israel(which is one of the richest countries) colleges are paid for by the government and therefore,most people over there attend college.
