This document discusses the concept of openness in education, focusing on its implications for learning in the future. It explores openness across four facets: open design, open delivery, open evaluation, and open research. Adopting more open practices could mean transparency in educational design, delivery, and evaluation. It could also foster better sharing of teaching ideas and a cultural change in learning and teaching practices. Defining and understanding openness is important from a research perspective and could lead to benefits like greater sharing of educational resources and a more evidence-based, research-led approach to teaching.
