The work brings together reference evidence on the production, distribution and pedagogical use of digital content in school education in Spain. Based on a comparative study of commercial and institutional platforms, and with contributions from national and international experts, the book offers an accurate diagnosis of the strengths and weaknesses of the current ecosystem, as well as specific proposals for teachers, administrations and edtech companies. In a context where the quality of digital material marks the difference between mere technification and authentic innovation, this work becomes an essential guide for informed and sustainable decision-making.
