There are many reasons why educational systems have differing methods. Here are some of the most common:

• Cultural differences. Different cultures have different values and beliefs about education, which can influence the methods used. For example, in some cultures, education is seen as a way to prepare students for a specific job, while in other cultures, it is seen as a way to develop the whole person.
• Historical factors. The history of a country can also influence its educational system. For example, the United States has a long history of valuing individual freedom and initiative, which is reflected in its educational system’s focus on critical thinking and problem-solving.
• Economic factors. The economic resources available to a country can also influence its educational system. Countries with more resources can afford to provide more teachers, smaller class sizes, and better facilities. This can lead to a more effective educational system.
• Political factors. The political system of a country can also influence its educational system. For example, countries with a strong central government may have a more uniform educational system, while countries with a more decentralized government may have more variation in their educational systems.
• The goals of education. Different countries have different goals for their educational systems. Some countries may focus on preparing students for the workforce, while others may focus on developing the whole person. These different goals can lead to different methods being used.
• The availability of technology. The availability of technology can also influence the methods used in education. For example, countries with more access to technology may be able to use online learning or other innovative methods.

It is important to note that there is no one “best” educational system. The best system for a particular country will depend on its culture, history, economic resources, political system, goals of education, and the availability of technology.

In the case of India, the education system is predominantly based on the traditional model of teaching, which focuses on rote learning and theoretical knowledge. This is due to a number of factors, including the country’s long history of tradition and its emphasis on academic achievement. However, there is a growing movement to reform the Indian education system to make it more student-centered and to focus on skills development.
