Understanding the processes related to gender construction requires a multi and interdisciplinary approach. Complexity emerges as a category of investigation and an end to be pursued, giving space to a plurality of voices, interpretations, and points of view. With such intellectual curiosity, the volume's authors questioned the inclusion and exclusion of these multiple voices in education. How has teaching on gender made room for this complexity? What views were included? Which ones were overlooked? What have educational models for children been privileged in the imagination? Which histories and stories have accompanied them in acquiring an awareness linked to gender? Through such important questions and many more, the volume highlights the gender changes that took place from mid-eighteen century to today in various contexts relating to formal and informal education through an international comparative perspective. The multiplicity of approaches, methodologies, and perspectives allows us to read and analyze these changes in a composite way, underlining little-known aspects of gender studies in the historical-educational field.
