Editorial for RLT special issue on mobile mixed reality

This special collection of Research In Learning Technology explores the state of the art of mobile mixed reality (MMR) in education. The special collection includes eight articles that cover; a systematic review of MMR in healthcare higher education, using mobile devices for connecting people to places, and a variety of case studies of implementing MMR in educational contexts. The range of papers illustrates the emergence of MMR as a platform for designing authentic learning environments in both formal and informal learning situations. The papers also highlight a general lack of engagement with new learning theories and models in the use of MMR to design transformative learning experiences
