What are the characteristics of experimental research in preschool education?

1, the research object is special and the research object is few * * *. All children grow up in different family environments, and what they hear every day is different. The assumptions put forward in the experiment are basically unsatisfactory.

2. There are few available research methods. One is historical reasons, and the other is the complexity of the discipline. There are not many methods that can be used, and intervention means cannot be imposed or few. Because of law, morality and children's vital interests, we can't take some extreme measures.

3. The experimental results can't be judged objectively, only subjectively. It is difficult to make a positive judgment on the influence of preschool education on children. Most of the current and past studies are commercialized, which deeply affects the objectivity of educational research.
