Today, we have an increasing store of research to evaluate the claims of educational tech. Where does it assist or upend our goals as a school? Where does it support or bypass our students’ intellectual sovereignty? Can it be used constructively?
This week on HeightsCast, writer and educator Andrew Cantarutti shares with us the research on digital tools, and especially AI, in K-12 education. In passionate detail, he also lays out how a school can cultivate the habits of attention by its curriculum, pedagogy, character, and even the physical school building.
