This edited volume is written in memoriam of Professor Emeritus Ubiratan D’Ambrosio (1932 – 2021), who was a well-known Brazilian mathematics educator and historian of mathematics. This book explores the diverse facets of D’Ambrosio’s work as well as his legacy and the later adaptation of his ideas around the globe. It starts with a preface written by his son, Alexandre D' Ambrosio, who shares his personal experiences growing up with this father and his love for discovery. The book is then divided into four sections: Past and Future: Ubi’s Way of Seeing Education in the Present Roots of Ethnomathematics Ethnomathematics in Action Trends in Ethnomathematics It features diverse points of view and experiences that explore mathematics and culture from researchers in the Americas, Africa, Europe and South Asia. Chapters range from personal explorations of D’Ambrosio’s impact to broader views of his research and work. This book forms part of the growing understanding of Ubiratan D’Ambrosio’s life, research, and the legacy he has left for millions of researchers, students and teachers worldwide. This book is appealing to anyone involved in mathematics education research as well as those interested in the history and future of mathematics education.

This book focuses on the development of four key issues in the development of modern Spain; knowledge, manufacturing, energy and telecommunications, and public works. If technology transfer from advanced nations to less developed systems always worked, then the whole world would now be rich. That this is not the case is so obvious, we might well expect that the history of the processes, successes and failures of technology transfer across nations would be a very well-established field of enquiry. In fact, the theme is still a developing one, and the present Special Issue centres on the case of Spain as exemplary in many respects. The collected essays focus upon the four major themes of knowledge, manufacturing, energy, and telecommunications and public works. Essays range in time from the 18th century to the present time, from studies of espionage and early links between craftsmen and savants, to the institutions of technology (from training systems, to private enterprise activity, or patents), to case-studies of silk manufacture, shipbuilding, mining, paper-making, and pharmaceuticals. Each essay offers a broad variety of material to bring to bear on a major problem of world development, past, present, and future.

This second edition of the International Handbook of Mathematics Teacher Education builds on and extends the topics/ideas in the first edition while maintaining the themes for each of the volumes. Collectively, the authors look back beyond and within the last 10 years to establish the state-of-the-art and continuing and new trends in mathematics teacher and mathematics teacher educator education, and look forward regarding possible avenues for teachers, teacher educators, researchers, and policy makers to consider to enhance and/or further investigate mathematics teacher and teacher educator learning and practice, in particular. The volume editors provide introductions to each volume that highlight the subthemes used to group related chapters, which offer meaningful lenses to see important connections within and across chapters. Readers can also use these subthemes to make connections across the four volumes, which, although presented separately, include topics that have relevance across them since they are all situated in the common focus regarding mathematics teachers. Volume 2, Tools and Processes in Mathematics Teacher Education, describes and analyze various promising tools and processes, from different perspectives, aimed at facilitating the mathematics teacher learning and development. It provides insights of how mathematics teacher educators think about and approach their work with teachers. Thus, as the second volume in the series, it broadens our understanding of the mathematics teacher and their learning and teaching.

This volume, The Brazilian Studies in the Philosophy and History of Science, is the first attempt to present to a general audience, works from Brazil on this subject. The included papers are original, covering a remarkable number of relevant topics of philosophy of science, logic and on the history of science. The Brazilian community has increased in the last years in quantity and in quality of the works, most of them being published in respectable international journals on the subject. The chapters of this volume are forwarded by a general introduction, which aims to sketch not only the contents of the chapters, but it is conceived as a historical and conceptual guide to the development of the field in Brazil. The introduction intends to be useful to the reader, and not only to the specialist, helping them to evaluate the increase in production of this country within the international context.

For a North American seeking to know the Mexican mind, and especially the sciences today and in their recent development, a great light of genius is to be found in Mexico City in the late 17th century. Tbe genius is that of one who surely may be counted as the first Mexican philosopher of nature, a nun of the Order of Saint Jerome: Sor Juana Ines de la Cruz. Sor Juana must speak for herself, from her penetrating exercise of an independent mind within a political and religious formation which denigrated women and circumscribed reason itself. To understand this world of ours, to join in an enlightenment which would be both natural and inspired, Sor Juana clearly understood the requirements of leaming, observing, logic and reasoning. In darkness foundering Words fail the troubled mind. For who, I ask, can light me When Reason is blind? Even now, after the great steps toward liberation of women, and the substantial scientific contributions toward sheer empirical awareness of both the multiple orders ofNature and the subtle aesthetics ofindividual art and social harmony, we too in the earthly world of the 20th century must affirm what she affirmed.
