Audrey Watters is the online learning sectors resident critic. For many years she has been "calling out" EdTech and big-tech's claims about learning in her blog Hack Education. Now she has crafted a comprehensive and critical-reflective look at EdTech from the Sidney Pressey's 1926 "positive reinforcement provider" through to present day AI enabled technologies. Well-written, Watters challenges the "transformation" narrative that often accompanies an emerging educational technology and, in doing, so challenges the "learnification" industry as a whole. Full of excellent examples and case vignettes, including wonderful stories of failed adventures (including some from repeat offenders), Watters offers a compelling narrative of caution and respect for the bigger purposes of education.
