Which of the following nations introduced co-education for the first time in the world?

In India, co-education has not been a very long practice. It started during the pre-independence period, when education movements began as a part of the national movement. It was realised that co-education was a part of modern education which reduced gender biases. Modern education started in India in the early part of the nineteenth century. Co-education is based on the feeling of gender equality and skill development, so that we can see women in top positions. Girls and boys look for the freedom to interact with each other, so that a healthy practice can be set instead of being conservative, suspicious and ignorant. In our rural areas we can still see separate schools for boys and girls. Now, co-education is practised in big towns and cities, in colleges, universities and other institutions, and this is perceived to be beneficial for complete personality development. In fact, Switzerland was the first nation to introduce co-education. Then this phenomenon spread to other western nations, and now it is a modern way of life. This system of education is very cost effective as well. It reduces the financial burden required for more separate buildings and teachers. A developing nation such as India has always been under financial distress, and we always look for better returns on investment in education. A better understanding between boys and girls is ultimately a sign of our family and social progress, as they may know better the intricacies of relationships. Boys are not posed as dangerous creatures; rather, boys must learn to treat girls in a respectful and civilized manner, so that the gender-linked crime rate comes down. Society can exert better social control and discipline, as boys behave decently in the presence of girls. Girls also come out of their social reservations. A healthy competition is generated, and they can explore their talent, skills and capabilities in the desired manner. This helps in the refinement of society.
