Has there been any action taken in non-Islamic societies to prevent the mixing of opposite genders?

In places like New York, some of the black educators of New York are trying to set up all boys’ school and all-girls school. It is a big struggle. People complain of being backwards and pressure the education department to integrate boys and girls together in schools. However, educators have found that boys and girls studying together doesn’t help. They are more effective when they study together with their own gender. They themselves are going back to the methodology revealed by the revelation.

There are also plenty of “Religious Institutes” of the Christo-Jewish religions that adhere to a single gender approach in their school systems. Furthermore, if one was to concentrate on this aspect, you would find gender space facilitation throughout different walks of life such as restrooms/locker rooms/ dormitories etc.
