The world of deviance in the classroom: Psychological experiments on schoolchildren in Weimar Germany.

The article uses three case studies from the 1920s to explore how psychologists and elementary school teachers employed psychological techniques to gain knowledge about elementary school children and their milieu. It begins by describing the role of the elementary school and the elementary school teacher in the Weimar Republic. It then discusses the so-called "observation sheets" that were used in elementary schools in the 1920s to gain insights into the mental and moral characteristics of pupils. Third, it examines psychological experiments undertaken in elementary school classrooms based on the exemplar case of a single teacher/experimenter, before concluding with a comparison of the two practices. I argue that psychology gained in standing through this history, becoming recognized as a foundational science in the context of education. Teachers used the professionalization of observation techniques in school to enhance their socio-epistemic status.
