Tech v Trust: scaling simulation for 21st C students Keynote for 4th International Conference on Medical Education Informatics (#MEI2021Conf) Using technologies to support and enhance our student learning has been deemed a ‘wicked challenge’ by successive Educause ‘New Media Horizons’ reports, in their annual scanning of educational ‘futures’ environments. The challenge is not the technology, nor access to wide range of resources – the challenge is with us as educators stepping up and seeking to implement at scale. Healthcare students have had to overcome the restrictions and implications of Covid-19 with many of their clinical skills moving online, and with limited opportunities to engage with their clinical practice partners. But what are the factors we should be considering when creating authentic learning experiences for our students? Reimaging our teaching practice is a contested area, and this talk will set out some potential responses for building capacity and emphasises the significant ‘trust’ plays in taking our work forward.
