This article describes the doctoral thesis proposal for designing a methodological guide for implementing cultural inclusion and cultural diversity projects with technological support in European educational institutions. This thesis addresses the urgent need for effective methodologies to implement cultural diversity and inclusion projects in educational institutions. Despite advances in educational policies, institutions require support in effectively integrating students from diverse cultural backgrounds. The research aims to develop a practical and adaptable methodological guide to help schools foster inclusive environments that celebrate cultural diversity. The study integrates qualitative and quantitative methodologies with a mixed methods approach to evaluate existing practices, identify gaps, and propose evidence-based strategies. Data will be collected through surveys, interviews, and focus groups at various European educational institutions to provide insights into best practices and areas that need improvement. Key outcomes include a comprehensive methodological guide, an evaluation of existing practices, and a continuous evaluation framework. This research will contribute significantly to culturally inclusive education and pedagogical practices and create educational environments that respect and embrace cultural differences with the support of technology.
