Many families with children are mothers with, very few fathers with, even if the kindergarten is also a female teacher. But did you know? In order to have a child with a high IQ, sometimes it is also necessary to let the father take the child. American scientists found after 12 years of research that if children are not brought up by their mothers but by their fathers, then the children’s IQ will be much higher and their academic performance is also the best, and they will be more likely to enter society in the future. Whether or not the father is involved in the early education of the child directly affects the intelligence level of 2-3 year old children. American scientists have found in their research that if a child is involved in more parental support during the age of 2, the child’s cognitive and language skills will develop very well, with the role of the mother but the role of the father should not be underestimated. Mothers are generally gentle and meticulous when it comes to educating their children, they take care of their children in various ways, which is very important and we don’t deny it, but on a certain level, the father’s education is also important and cannot be replaced by the mother. In a longitudinal study done by a professor at a Canadian university, they tested a portion of the children’s family situation, whether the father was involved in the child’s development, whether there was conflict between the couple and the cognitive ability of the child in the family environment, and found that there was a strong link between the parents’ literacy level and the child’s intelligence after the family environment situation was eliminated. If both parents have a low level of literacy, the active participation of the father in the child’s development is particularly important. Fathers nurture their children’s qualities, they will let their children learn courage, independence and confidence, openness and strength in the ordinary. Fathers will not be as careful as mothers, they will let their children discover for themselves. They will let their children think for themselves, pursue excitement, and challenge difficulties. Although they are not as careful and clean as mothers, they are still very helpful to their children’s growth. Many people say that during their growing up life is taken care of by moms, and on top of problematic decisions are pointed out by dads, so parents are missing one. Dads should adopt a motivational approach to educate their children, preferably with sports or games, so that in the process of playing dads become the child’s game partner, the child will be excited to be with their dad, feel treated equally, and sometimes even adore their dad, who is the source of emotional satisfaction and the object of the child’s dependence. From the above discussion, it is clear that fathers must be involved in their children’s education so that they can develop better and raise their IQ by one level.
