New technologies provide us with new opportunities to create new learning experiences, leveraging research from a variety of disciplines along with imagination and creativity. The Learning Ideas Conference was created to bring researchers, practitioners, and others together to discuss, innovate, and create. The Learning Ideas Conference 2025 was the 18th annual conference and was held as a hybrid event. The conference took place from June 11-13, 2025, both in New York and online, and included a Special Session from IGIP, the International Society for Engineering Pedagogy. The conference also held additional online-only conference days on May 28 and 29, 2025. Topics covered in this volume include, among others: uses of artificial intelligence in learning, online learning methodologies, case studies in university and corporate settings, new technologies in learning (such as, along with AI, virtual reality, augmented reality, holograms, and more), adaptive learning, and project-based learning. The papers included in this volume may be of interest to researchers in pedagogy and learning theory, university faculty members and administrators, learning and development specialists, user experience designers, and others.
