There are many reasons why non-native English teachers are often better than native English speakers. Here are some of the most common reasons:
1. Non-native English teachers have to work harder to be understood. This means that they typically put more effort into enunciating clearly and using simple language. As a result, their students usually end up with a better understanding of the material.
2. Non-native English teachers are often more familiar with the grammar rules of the language. This is because they had to learn them in order to be able to speak fluently themselves. As a result, they can often help their students avoid common mistakes and improve their overall grammar skills.
3. Non-native English teachers typically have a better understanding of cultural differences and can help their students navigate them more effectively. This is because they themselves have experienced culture shock and know how difficult it can be to adjust to a new culture. As a result, they can offer valuable insights and guidance to their students who may be struggling with cultural adjustment issues.
