"This study is based on Korean students, ranging from elementary to high school. Specifically, it examined how their parents' educational support activities and the children's perception to such support activities are different according to children‘s demographic variables and home environment variables. In order to achieve such purpose in this study, data has been collected through self-rating surveys done by 929 students(360 elementary school students, 300 middle school students, 269 high school students). The major findings were as follows: First, elementary school students were perceived school-related support activities and controlling activities perform more than middle and high school students. The same is for sons more than daughters, groups of higher grade than groups of middle and lower grade. In the case of making a home-learning environment, there was an interaction effect between the child's age and grade. Also, groups whose father's educational level is graduating college or lower, tend to show less activities that form a home-learning environment and controlling activities, compared to that of graduates of university and even higher level. In contrast, groups of higher economic level tend to have more activities that form a home-learning environment and controlling activities. In case of school-related support activities, there was an interaction effect between father's educational level and economic level. Second, parents' activities to improve child's grades and activities that form a physical educational environment were perceived most helpful in groups of highest grade. Elementary school students and students who are in highest grade groups were perceived school-related support and controlling activities to be helpful to themselves. Meanwhile, as to the perception of helpfulness of activities that make a home-learning environment, there was an interaction effect between the child's age and grade. As to the perception of helpfulness of grade-beneficial activities, activities that form a home-learning environment and controlling activities, were perceived parental support to be most helpful to groups with the highest economic level. In the case of school-related support activities, interaction effect appeared both between father's educational level and economic level, and between mother's employment condition and economic level. These results show that regarding parents' educational support activities, as the age of the child increases, the content of the support activities have to change. Also, a support system for underprivileged families of father's educational level and household economic level should be constructed by the government."
