This study aims at looking at changes in families and of education paradigms due to informationization, prospecting changes in families’ education functions, and seeking political implications to cope with them. The informationization has changed education paradigms from rigid and closed ones to flexible and open ones. Changes in education paradigms can be suggested as changes in information of education objects, role changes among education subjects, changes of new education methods, and the spread of lifelong learning, etc. Changes in families and education paradigms due to informationization will produce considerable changes in families’ education functions. In perpendicular sphere, family’s direct participation in education, enlargement of parents’ role using the information media and increased family’s role in creativity education are suggested. In horizontal sphere, diversification of education subject in family, increased needs for family life education, and reinforcement of supports for family’s lifelong education are suggested. Finally some political implications for countermeasure on changes in family’s education function due to informationization are proposed.
