This book constitutes the refereed proceedings of the 2nd International Conference on Emerging Technologies and Educational Innovation (ICETEI 2025), organized by the Red de Educación con Tecnologías Emergentes (EDUTEM) and held virtually on November 13–14, 2025. The selected papers reflect both theoretical advances and applied research across four main thematic areas: digital technologies and smart systems; applied computing and intelligent solutions; digital education and learning analytics and innovative technologies for teaching. The conference attracted submissions from Latin America, Europe, and other regions, highlighting its growing international scope. Out of 50 contributions received, 24 papers were accepted for publication after a rigorous double-blind review process. This second edition of ICETEI reinforces the importance of fostering collaboration between educators, computer scientists, engineers, and policy-makers. The proceedings provide valuable insights into how emerging technologies and innovative pedagogical approaches can advance equity, engagement, and sustainability in the digital age.
