Transmission of socio-cultural values is seen as a kind of "black box." A student usually obtains their socio-cultural values from their role models (probably their parents or other adults), but how this socialization process works is not explicitly spelled out. Information on socio-cultural values is regarded as a fact that applies to everyone in all circumstances. One consequence is that information on socio-cultural values can then be disseminated further, spreading through social networks on the broader community and population. Different experimental paradigms can simulate the spread of information on socio-cultural values through social networks with different structural properties. This study aims to analyze the socio-cultural values in the traditions of the Yogyakarta people transmitted through education. This study's approach is qualitative, with research subjects of the principal, teachers, and students. Data collection techniques were through observation, interviews, and documentation. The analysis includes data reduction, data display, and conclusion drawing/verification. The results showed that (1) transmission of socio-cultural values is not carried out by design; (2) socio-cultural values transmitted to students such as cooperation values, politeness, and discipline; and (3) the process of transmitting socio-cultural values carried out in the classroom learning activities and extracurricular activities.
