Which of the following three subjects is better for Jiangsu preschool education undergraduate self-study exam? 1, research methods of preschool education 2, preschool education in the contemporary world 3, child development The following are my personal thoughts:

1. Research methods of preschool education: Many research methods draw lessons from natural science and humanities, and there are many experiments. If science is better, I suggest choosing this one.

2. Preschool education in the contemporary world: the content involves more foreign educational history and pedagogy. There are many people involved, many systems and regulations, which are very complicated. If liberal arts is good, I suggest choosing this one. It's just rote learning. There is nothing to understand.

3. Child development: The content involves psychology. It's abstract, not easy to understand, and widely used. It's no use just knowing the principle. I don't really recommend choosing.
