Preschool education advocates curriculum integration, that is, the organic integration of various subjects in the curriculum, rather than the teaching of different subjects like primary and secondary schools. In the process of "knowing the triangle", children enrich their experience and understanding of the triangle in listening to stories, observing the environment, puzzles and other activities, and feel fresh and interesting in understanding and exploring the triangle, which has a positive role in promoting children's knowledge, skills, intentions and emotions. It is natural to say that this is suitable for children's early education. If you hurt your children's intentions and emotions by teaching them knowledge too early, it will be very worthwhile, because intentions and emotions have a longer-term impact on their future development. This is probably an excessive early education similar to "encouraging seedlings". In a word, preschool education is a subject with rich connotations, and new research results and educational practices emerge one after another, which requires teachers to broaden their horizons and study and practice in various ways in order to better grasp it. If teachers or parents adopt early education that is suitable for children's cognitive ability and can arouse children's interest, it is very beneficial and there is no need for "excessive early education"; However, if "premature education" is adopted, children may have mastered some knowledge and skills earlier, but their intentions and feelings that have a longer-term impact on their growth have been damaged. Is this "premature education"? Perhaps it can only be regarded as a narrow vision, fearless and ignorant early education. In the long run, "non-disciples are useless and harmful." It is not a problem to teach early, but how to teach with educational wisdom is the problem. If the method is proper, there is no "excessive early education"; If the method is improper, one-sided attention to children's knowledge and skills, ignoring the growth of intention and emotion, it may indeed have a negative effect of encouraging children, which seems to be temporarily "high", but it is not conducive to children's future.
