In 1927, nursery school educator Lucy Sprague Mitchell heralded Jean Piaget's psychology as of "outstanding interest" and wrote in "Progressive Education" that it should be of "immense service" to psychologists, teachers, and parents. In 1929, psychologist Lois Meek praised Piaget's research in the National Society for the Study of Education's yearbook on preschool and parental education. In 1931, the National Association for Nursery Education bibliography on nursery school-based research, for which Meek was on the editorial board, included no mention of Piaget at all. In this article, the author examines the transitory connections between psychology and education such as that between Piaget's psychology and the nursery school movement in the 1920s and 1930s.
