The Experience, Represent, Apply (ERA) heuristic is an innovation of the Early Learning STEM Australia (ELSA) project. It provided educators with an approach that embeds digital technologies in play-based learning in such a way that the focus of the learning remains on the child and not on the device. This paper reports on the experiences of early years educators and indicates that the ERA heuristic was instrumental in helping educators to integrate digital technologies in their everyday activities to promote engagement with STEM.
