Friedrich Fröbel’s conception of crystallography and the mathematical education at the 19th century kindergartens

The history of mathematics education is an interdisciplinary research area that is experiencing a significant development and this book presents recent work in this area. This book is the result of the sixth conference ICHME (In-ternational Conference on the History of Mathematics Education) that took place at CIRM, Luminy (France) from 16th to 20th of September 2019. Nowadays, the history of education is of the utmost importance for assessing the general development of the educational system(s) in which mathematics education occurs. Usually, the history of education is confined to history within a given civilization, country or nation. However, the quality of the research for a given nation is enhanced when situated among various specific cases, and comparative studies provide essential tools to broaden the perspectives to an international level. Moreover, mathematics, as a school discipline, has always functioned at the crossroads between general education and professional training, thus relating its teaching history to professional working environments as well. The themes dealt with in this book reflect this wide area of research. The book contains 28 chapters grouped in four parts concerning teaching of particular mathematical domains, teaching in cultural and national contexts, pedagogical movements and reforms, and methods of teaching.
