An educational design language (EDL) is a notation that can be used to express the design of a learning environment, instructional sequence and more generally a design that has some intention to educate. The Larnaca declaration on learning design [@dalzielLarnacaDeclarationLearning2016|(Dalziel et al., 2016)] relates it to musical notation, where the expression of sound through notation did not remove the beauty present, but produce a medium through which ideas could be shared, elaborated and built upon. An [[Educational modelling language|educational modelling language (EML)]] is a type of EDL. I also create [[Pedagogy modelling language|pedagogy modelling language (PML)]] to represent a form of pedagogical expression that sits before the EDL, that is reasoning on pedagogical knowledge can help us derive design decisions. # References Dalziel, J., Conole, G., Wills, S., Walker, S., Bennett, S., Dobozy, E., Cameron, L., Badilescu-Buga, E., & Bower, M.
