Fostering tolerance and inclusiveness in multicultural societies is increasingly vital, particularly in educational settings. Understanding the impact of parental involvement and school events on students’ attitudes toward these values is essential for promoting social cohesion and preparing future generations for an interconnected world. This study applies Bayesian Mindsponge Framework (BMF) analytics to a representative dataset of 2,069 primary, secondary, and high school students across Vietnam. It explores how parental discussions and participation in multicultural school events influence students’ attitudes toward tolerance (...) and inclusiveness. The findings indicate that parental discussions about collaboration with individuals holding diverse perspectives, as well as participation in multicultural events, are positively associated with students’ tolerant attitudes. Furthermore, parental discussions about cultures and histories of different countries, collaboration skills, and conflict resolution skills are positively linked to students’ inclusiveness. The study highlights that while multicultural school events provide valuable opportunities for students to engage with diverse cultures and broaden their perspectives, consistent parental involvement through meaningful discussions is likely critical for reinforcing inclusive values. A collaborative approach between schools and parents can more effectively nurture tolerance and inclusiveness among students. Future research could examine the long-term effects of these interactions and identify specific activities that most effectively foster inclusive attitudes. (shrink)
