Vorwärts-Rückwärts zum Begriff. Konstruktion und Re-Konstruktion von Zugfiguren.
Autoren: Ulrich Kortenkamp, Christian Dohrmann
(2016)
Zusammenfassung: Zugfiguren, d.h. dynamische Realisierungen von Konstruktionen im DGS, sind ein gutes Werkzeug, um die heuristischen Strategien des Vorwärts- und Rückwärtsarbeiten zu unterstützen. Was muss man über ein Parallelogramm (oder ein anderes spezielles Viereck) wissen, um dieses zu (re-)konstruieren? Die Beschäftigung damit führt zu elementaren Konstruktionsschritten wie auch zu den Typ-bestimmenden Eigenschaften spezieller Vierecke.

Recent research on geometry education: an ICME-13 survey team report

This survey on the theme of Geometry Education (including new technologies) focuses chiefly on the time span since 2008. Based on our review of the research literature published during this time span (in refereed journal articles, conference proceedings and edited books), we have jointly identified seven major threads of contributions that span from the early years of learning (pre-school and primary school) through to post-compulsory education and to the issue of mathematics teacher education for geometry. These threads are as follows: developments and trends in the use of theories; advances in the understanding of visuo spatial reasoning; the use and role of diagrams and gestures; advances in the understanding of the role of digital technologies; advances in the understanding of the teaching and learning of definitions; advances in the understanding of the teaching and learning of the proving process; and, moving beyond traditional Euclidean approaches. Within each theme, we identify relevant research and also offer commentary on future directions.

Model Development in Scientific Discovery Learning with a Computer-Based Physics Task
Autoren: Saskia Kistner, Regina Vollmeyer, Bruce D. Burns, Ulrich Kortenkamp
(2016)
Based on theories of scientific discovery learning and conceptual change, this study explores students' preconceptions in the domain of torques in physics and the development of these conceptions while learning with a scientific discovery learning task. Referring to a three-space theory of scientific discovery learning (Burns & Vollmeyer, 2000), the focus was on the content of model space, which is supposed to contain the current conceptualization/model of the learning domain, and on its change through hypothesis testing and experimenting. A multiple-choice test for assessing students' models of torques was developed and used in a study with secondary school students (N=47) who learned about torques using computer simulations. We identified those aspects of torques about which students had physically correct conceptions, and those about which misconceptions were predominant. Working with the computer simulations led to replacement of some misconceptions with physically correct conceptions, though some misconceptions were still common after learning. Analyzing individual differences in model development, we found that an intense use of the simulations was associated with the acquisition of correct conceptions. The three-space theory provided a useful framework for understanding conceptual change in scientific discovery learning.

Jonathan M Borwein (1951–2016): exploring, experiencing and experimenting in mathematics – an inspiring journey in mathematics.
Autoren: Ulrich Kortenkamp, John Monaghan,Luc Trouche
(2016)
Summary: Jonathan M Borwein died on August 2nd. He was a major figure in the field of experimental mathematics. His death, at 65, was an astonishment for his family and his colleagues. We three, as mathematics educators who have worked with Jon, have been asked to pay homage to his life and his work. But we three have only shared a part of Jon's tremendous appetite for life and work, so we barely scratch the surface of the significance of his work. Ulli writes about Jon's experimental mathematics, Luc writes about the implications of Jon's work for mathematics education and John writes about Jon, culture and mathematics.

Autoren: Martin von Gagern, Ulrich Kortenkamp, Jürgen Richter-Gebert, Michael Strobel
(2016)
The CindyJS Project brings interactive mathematical visualization to a broad variety of devices. Using projective geometry, homotopy methods and well tuned algorithms the CindyJS project is one of the first real time capable software projects in this field that at the same time approaches high-level mathematical descriptions and performance.
