Rechenwege für die Multiplikation und ihre Umsetzung: Einsicht in operative Beziehungen erlangen und aufgabenadäquat anwenden (Perspektiven der Mathematikdidaktik)
by Martina Greiler-ZauchnerIm Fokus der vorliegenden Untersuchung stehen Rechenwege für Multiplikationen einstelliger mit zweistelligen Zahlen und damit zusammenhängende Einsichten von Kindern in die zugrundeliegenden operativen Beziehungen. Diese werden vor und nach der Umsetzung eines Lernarrangements in Klassen der dritten Schulstufe erhoben. Neben dem sicheren Anwenden verschiedener Rechenwege sollten Kinder Einsicht in Beziehungen und Strukturen entwickeln und Rechenwege zunehmend aufgabenadäquat wählen, indem sie über vorteilhaftes Rechnen in Bezug auf Aufgabenmerkmale reflektieren.Die vor und nach der Umsetzung des Lernarrangements gezeigten Rechenwege werden klassifiziert. Darüber hinaus wird in der vorliegenden Arbeit eine empirisch begründete Typisierung nach den verwendeten Rechenwegen generiert. Die Typenbildung unterscheidet in Abstufungen Kinder, die ausschließlich den Universalrechenweg über stellengerechtes Zerlegen in eine Summe nutzen und Kinder, die zusätzlich besondere Aufgabenmerkmale erkennen und anwenden. Weitere Ergebnisse liefern Aussagen zu Hürden, die in den Lernprozessen auftreten können sowie zu erreichbaren Lernzielen in Bezug auf ein aufgabenadäquates Vorgehen.
Rechnen lernen und Flexibilität entwickeln
by Elisabeth Rathgeb-Schnierer Charlotte RechtsteinerDieser Band thematisiert vielseitig und aspektreich das flexible Rechnen in der Grundschule. Die Notwendigkeit der Förderung flexibler Rechenkompetenzen im Mathematikunterricht der Grundschule ist unumstritten und über die Zielrichtung des Mathematiklernens besteht Konsens: Kinder sollen bei der Ablösung des zählenden Rechnens begleitet und zum flexiblen Rechnen herausgefordert werden. Was bedeutet dies aber konkret? Was verstehen wir unter flexiblem Rechnen und wie kann flexibles Rechnen im Sinne eines kumulativen Aufbaus über die gesamte Grundschulzeit bei Kindern mit verschiedenen Lernvoraussetzungen gefördert werden? Diesen Fragen wird im Buch nachgegangen: Im Vordergrund steht dabei das Ziel, die Thematik einerseits theoretisch detailliert aufzuarbeiten, andererseits sie im Hinblick auf Unterricht zu konkretisieren. Die theoretische Aufarbeitung beschäftigt sich zunächst mit dem Prozess des Rechnens und darauf aufbauend allgemein mit Überlegungen zum Rechnenlernen und zur Entwicklung von Flexibilität. Die unterrichtspraktischen Aktivitäten im Rahmen der Zahlenblickschulung beziehen sich vorwiegend auf die Klassen 1 bis 3, da der Schwerpunkt des flexiblen Rechnens im Bereich des Zahlenrechnens im Zahlenraum bis 1000 liegt. Zielgruppen dieses Buches sind sowohl Studierende, Referendare und Referendarinnen als auch Lehrerinnen und Lehrer der Primarstufe.
Reciprocal Learning for Cross-Cultural Mathematics Education: A Partnership Project Between Canada and China (Intercultural Reciprocal Learning in Chinese and Western Education)
by Sijia Cynthia Zhu Shu Xie Yunpeng Ma Douglas McDougallThis edited volume examines new ways of teaching mathematics through a cross-cultural reciprocal learning project between sister schools in Canada and China. Situating teacher learning in the intersection of the two different school systems, curriculums, and cultures of mathematics learning and teaching in both nations, this volume offers teachers a unique and much-needed perspective on how practices between countries become more and more likely shaped by each other in the emerging global society. Born out of a comparative study project sponsored by the SSHRC, this volume compiles five years' worth of findings from reciprocal partnerships between researchers, teachers, school administrators, and students from both nations. Through the process of reciprocal learning and narrative inquiry, the research described in these chapters illuminates the unknown and shares newly-created mathematics education knowledge.
Reciprocity, Spatial Mapping and Time Reversal in Electromagnetics
by C. Altman K. SuchyThis long awaited second edition traces the original developments from the 1970s and brings them up to date with new and previously unpublished material to give this work a new lease of life for the early twenty-first century and readers new to the topic. In the winter of 1970-71, Colman Altman had been finding almost exact symmetries in the computed reflection and transmission matrices for plane-stratified magnetoplasmas when symmetrically related directions of incidence were compared. At the suggestion of Kurt Suchy the complex conjugate wave fields, used to construct the eigenmode amplitudes via the mean Poynting flux densities, were replaced by the adjoint wave fields that would propagate in a medium with transposed constitutive tensors, to yield a scattering theorem - reciprocity in k-space -- in the computer output. To prove the result analytically, one had to investigate the properties of the adjoint Maxwell system, and the two independent proofs that followed, in 1975 and 1979, proceeded according to the personal preference of each of the authors. The proof given in this volume, based on the hindsight provided by later results, is much more simple and concise. Later, when media with bianisotropic constitutive tensors were investigated, it was found that conjugate (reciprocal) media and wave fields could be formed by any orthogonal spatial mapping of those in the original problem, after media and fields were reversed in time. The result was still quite general and not limited to stratified systems. The second line of development was to find the link between reciprocity in k-space and Lorentz reciprocity involving currents and sources in physical space. This was done for plane-stratified media by applying the scattering theorem to the plane-wave spectrum of eigenmodes radiated by one current source and reaching the second source. The reverse linkage between Lorentz reciprocity and reciprocity in k-space had already been found. However, this was the first time that the results were presented in a systematic and mathematically well-defined procedure to serve as a tool for solving problems of reciprocity and scattering symmetries. The use of time reversal gives rise to problems of causality when sources are present, but when the interaction between two systems is involved the non-causal effects are irrelevant. The insight gained during these investigations enabled the authors to present many of the earlier theorems and results, both their own and those of others, in a compact and unified approach, which has been the main strength of this book. This new edition has been revised, corrected and updated where necessary to give a complete picture of this interesting topic for the present generation of scientists.
Reckonings: Numerals, Cognition, and History
by Stephen ChrisomalisInsights from the history of numerical notation suggest that how humans write numbers is an active choice involving cognitive and social factors.Over the past 5,000 years, more than 100 methods of numerical notation--distinct ways of writing numbers--have been developed and used by specific communities. Most of these are barely known today; where they are known, they are often derided as cognitively cumbersome and outdated. In Reckonings, Stephen Chrisomalis considers how humans past and present use numerals, reinterpreting historical and archaeological representations of numerical notation and exploring the implications of why we write numbers with figures rather than words.
Reclaiming the Forest: The Ewenki Reindeer Herders of Aoluguya
by Åshild Kolås Yuanyuan XieThe reindeer herders of Aoluguya, China, are a group of former hunters who today see themselves as “keepers of reindeer” as they engage in ethnic tourism and exchange experiences with their Ewenki neighbors in Russian Siberia. Though to some their future seems problematic, this book focuses on the present, challenging the pessimistic outlook, reviewing current issues, and describing the efforts of the Ewenki to reclaim their forest lifestyle and develop new forest livelihoods. Both academic and literary contributions balance the volume written by authors who are either indigenous to the region or have carried out fieldwork among the Aoluguya Ewenki since the late 1990s.
Recollections of a Jewish Mathematician in Germany
by Abraham A. FraenkelJiska Cohen-MansfieldAbraham A. Fraenkel was a world-renowned mathematician in pre-Second World War Germany, whose work on set theory was fundamental to the development of modern mathematics. A friend of Albert Einstein, he knew many of the era's acclaimed mathematicians personally. He moved to Israel (then Palestine under the British Mandate) in the early 1930s. In his autobiography Fraenkel describes his early years growing up as an Orthodox Jew in Germany and his development as a mathematician at the beginning of the twentieth century. This memoir, originally written in German in the 1960s, has now been translated into English, with an additional chapter covering the period from 1933 until his death in 1965 written by the editor, Jiska Cohen-Mansfield. Fraenkel describes the world of mathematics in Germany in the first half of the twentieth century, its origins and development, the systems influencing it, and its demise. He also paints a unique picture of the complex struggles within the world of Orthodox Jewry in Germany. In his personal life, Fraenkel merged these two worlds during periods of turmoil including the two world wars and the establishment of the state of Israel. Including a new foreword by Menachem Magidor Foreword to the 1967 German edition by Yehoshua Bar-Hillel

Reconceptualizing Early Mathematics Learning
by Joanne T. Mulligan Lyn D. EnglishThis book emanated primarily from concerns that the mathematical capabilities of young children continue to receive inadequate attention in both the research and instructional arenas. Research over many years has revealed that young children have sophisticated mathematical minds and a natural eagerness to engage in a range of mathematical activities. As the chapters in this book attest, current research is showing that young children are developing complex mathematical knowledge and abstract reasoning a good deal earlier than previously thought. A range of studies in prior to school and early school settings indicate that young learners do possess cognitive capacities which, with appropriately designed and implemented learning experiences, can enable forms of reasoning not typically seen in the early years. Although there is a large and coherent body of research on individual content domains such as counting and arithmetic, there have been remarkably few studies that have attempted to describe characteristics of structural development in young students' mathematics. Collectively, the chapters highlight the importance of providing more exciting, relevant, and challenging 21st century mathematics learning for our young students. The chapters provide a broad scope in their topics and approaches to advancing young children's mathematical learning. They incorporate studies that highlight the importance of pattern and structure across the curriculum, studies that target particular content such as statistics, early algebra, and beginning number, and studies that consider how technology and other tools can facilitate early mathematical development. Reconceptualising the professional learning of teachers in promoting young children's mathematics, including a consideration of the role of play, is also addressed.

Reconfiguring Relations in the Empty Nest: Those Who Leave and Those Who Stay (Palgrave Macmillan Studies in Family and Intimate Life)
by Christophe Giraud Magdalena Żadkowska Marta Skowrońska Filip SchmidtThis edited volume traverses the spectrum of experiences that take place after children leave the family home and parents find themselves in the "empty nest" stage of life. Rather than focusing on measuring the intensity of empty nest syndrome or asking whether parents' marital satisfaction increases or decreases in this phase, the authors present rich qualitative data from across Poland and France to show that there is great variation in how families experience the empty nest, developing both a study on intimacy and love and on family solidarity. Throughout the book, themes of mixed emotions, nuanced attitudes, contradictions, and dissonance are explored while shedding light on "supporting actors" of the empty nest transition, such as family pets and material objects.
Reconstructing the International Tax System: An Alternative to Pillar One (Contributions to Economics)
by Elizabeth RosenthalSource-based taxation and the arm’s length standard have been foundational elements of the international tax system for many decades. With the advent of the highly digitalized platform firm, the OECD and many other stakeholders assert that these principles have been rendered obsolete. In their stead, these stakeholders have proposed an alternative hybrid international tax system. Under this proposed hybrid system, the long-standing profit allocation rules would be applied in the first instance to determine the preliminary attribution of in-scope multinational firms’ taxable income to individual taxing jurisdictions. These results would then be subject to a secondary reallocation designed to ensure that a portion of such firms’ taxable income is attributed to, and taxable by, jurisdictions in which consumers and users reside (“market jurisdictions”). This secondary allocation – the core of the OECD’s Pillar One and an essential element of its two-pronged “Pillar One-Pillar Two Solution” – explicitly deviates from both the arm’s length standard and the principle of source-based taxation. For many reasons, examined in this book, the OECD’s Pillar One would not provide for the effective taxation of highly digitalized platform firms, and, by extension, it would not stabilize the international tax system. The author argues that source-based taxation and the arm’s length standard are entirely compatible with the attribution of a portion of highly digitalized platform firms’ taxable income to market jurisdictions. However, new transfer pricing methodologies and a revised definition of ‘control’ for transfer pricing purposes are required to achieve this result. Combining important findings and insights from academic research in a variety of fields with the author’s extensive practical experience in both public and private spheres, this book is appropriate for academics as well as private sector advisors in the fields of transfer pricing and international tax, chief financial officers of multinational corporations and tax policy analysts.
