The thesis addresses the urgency of a sustainable society, emphasizing the importance of education in promoting values and competencies in the environmental field. Social inclusion, especially for individuals with functional diversity, and the transformative role of schools are crucial. Information and Communication Technologies (ICT) play a crucial role in educational innovation. The doctoral thesis is integrated into the European SUSKIDS Education Project, aiming to provide guidance and pedagogical strategies to professionals for imparting sustainable knowledge to individuals with Down Syndrome. It analyzes the impact of a virtual platform on sustainability learning for this group, focusing on three main aspects: the use of digital tools in education, the presentation of an adapted digital platform, and its potential educational and support scope for the target audience.The research has been carried out in three phases. The first involved a literature review on three aspects: digital resources and virtual environments in education for individuals with Down Syndrome, integration of sustainability content, and evaluation of the educational process. The second phase collected information to develop instructional material and methodological guides, focusing on providing support to professionals and families, designing an adapted virtual platform, and assessing its usability and learning outcomes for individuals with Down Syndrome. The third phase involves verifying the utility of the SUSKIDS platform through the analysis of diverse data using descriptive statistics and Text mining techniques.The assessment of participant satisfaction with the materials and usability of the platform is crucial. The anticipated results of this research are expected to make significant contributions to understanding the adaptation of digital resources to the learning style of individuals with Down Syndrome, supporting their development as active citizens, and enhancing their future employability. The implementation of improvements based on the findings will conclude the cycle of this study focused on continuous improvement.
