Early education refers to education from birth to preschool in a broad sense, and early learning in a narrow sense. Some countries began to learn reading, writing and calculation ahead of time, and started discussions and experiments in formal education ahead of time. But others think that early education should focus on developing intelligence. Others believe that early education should be extended to prenatal education before the mother is born. Family education has a great influence on early education.
It is generally believed that early education is mainly aimed at infants aged 0-3, and whole-brain education should be the whole stage of children and primary schools.
