Who will play a bigger role in a child's development? Personally, I believe that teachers are more influential once children start school, mainly because they are more familiar with teaching methods. For example, they can arrange some drills and class activities. They have a better understanding of how to make every lesson lively and stimulating to engage kids. On the other hand, they can also design some quizzes to monitor student's progress, which helps in improving children's learning outcomes. And those students who meet the requirements are more likely to go to university afterwards.
