This study analyzes images of mother and father as portrayed in the Korean language textbook for grammar school students under the 2015 revised national curricula, using the content analysis method. The analysis results are as follows: First, mothers are portrayed as figures that are kind and provide a sense of security, but also become stern when they teach disciplines to children. Second, both mothers and fathers play the role of assisting their children to lead a worthy life, rather than directly teaching values to them. Third, both parents take care of children’s upbringing and house chores, and mothers’ participation in economic activities is emphasized. Fourth, both parents take part in motivating their children with compliments, and share a responsibility of children’s education. Fifth, compared to fathers, mothers put more pressure on children and wield more control over them to ensure successful outcome of private education. Sixth, mothers and fathers sometimes give orders to children, and compromise with the world, but eventually overcome their weaknesses with love for their children. Seventh, fathers are sometimes portrayed as incompetent and shabby figures, and thus, an embarrassment to their children. These show that the dichotomous gender stereotype of parents has been substantially mitigated over time. However, description of parents in school textbook still has limitations in presenting their role as an emotional supporter and an educator for their children. More social discourse needs to be encouraged, led by parents, to discuss how to describe mothers and fathers in the Korean language textbook.
