This document discusses the critique of educational institutions in the 1970s and its relationship to theories of "liquid pedagogy" and "deschooling" in the 21st century. It argues that the critique of schools in the 1970s both reflected and contributed to the emergence of a new social imaginary characterized by distrust in large educational institutions. Further, it claims that liquid pedagogy has its roots in deschooling theories from the 1970s, though the relationship is one of "homothetic transformation" rather than a straight line. The document analyzes how these critiques and theories can provide new historical perspectives on changes in education.
