- In this paper we report on a framework for analyzing progress in concept knowledge as represented in textbooks. The framework is based on theories of Vergnaud, combined with a theory of Bruner. Two Swedish textbook series are analyzed with respect to how they introduce mathematical content and how it supports the progress of concept knowledge throughout school years. The analysis is restricted to the conceptual field of quotient constructions. We classified representations in terms of situational, iconic and symbol system representations. Results show that the investigated textbooks provide students with the same limited explanations in iconic representations of quotient constructions from year 3, when it is introduced, to year 9. We argue that our theory for progress in concept knowledge, together with our framework for analyzing progress, can be used by teachers and curriculum developers to organize instruction.

Polysemy and the role of representations for progress in concept knowledge

Conference paper (peer-reviewed)abstract
- Mathematics is a polysemic enterprise, where the same name is given to different things. Polysemy is present whenever mathematical patterns identified in different circumstances share the same structure. This structure will be subsumed under the same mathematical symbolism. Therefore, it is of interest to theorize upon progress in concept knowledge, with respect to the polysemic nature. We argue that progress in concept knowledge involves an epistemological shift that occurs when the meaning introduced by situations and iconic representations is replaced by meaning residing in non-iconic representations that exists independent of the situations and iconic representations. Our theorization can be used in teaching design and by curriculum developers.

The influence of psychedelics and toxicity in JG Ballard and Tom Wolfe's representations of petroculture

Journal article (peer-reviewed)abstract
- In my reading of Ballard's short story 'Dream Cargoes', I find a post-growth imaginary that focuses on a profound species-wide change of pace in the context of future nano- and biotech waste. I compare this to Tom Wolfe's heady account of the Merry Pranksters set during the Great Acceleration of the 1960s and 1970s. While Wolfe captured multiple fragmented points of view located in scattered time frames in his account of the Pranksters, Ballard is suggesting that time and its specific contemporary associations with extinction, renewability and futurity has become a central concern for humanity at large. I argue that literary representations of toxicity yield insight by awakening the reader to the ultimate limits of consumer culture. Thus, this essay offers an approach to fictions such as Ballard's and Wolfe's seeing them as essential resources for assessing toxicity in our lives as a source of insight as well as motivation to look for alternatives to petroculture.

Andreas Gryphius’ Sonette : Eine Interpunktionsgeschichte
- 2018
-
In: Studia Neophilologica. - : Informa UK Limited. - 0039-3274 .- 1651-2308. ; 90:Supplement 1, s. 88-113

Journal article (peer-reviewed)abstract
- Die vorliegende Arbeit untersucht die Versionen der 29 Sonette von Andreas Gryphius (1616–1664), die in allen der zu seinen Lebzeiten erschienenen Drucke vorliegen. Drei Aspekte der Gedichte werden im Sinne eines erweiterten Interpunktionsbegriffs berücksichtigt: Die Sonettgraphie und Seitengestaltung, die Interpunktionszeichen und die Hervorhebung durch Großschreibung.Die Interpunktion der Sonette wurde ständig revidiert, und es lassen sich bedeutende Unterschiede feststellen. Wer dafür verantwortlich war – der Dichter oder die verschiedenen Buchdrucker – lässt sich mit letzter Sicherheit nicht entscheiden. Doch ist wahrscheinlich, dass den Buchdruckern größere Bedeutung für die Gestaltung der Interpunktion zuzumessen ist als dem Autor selbst.Die Analysen machen auch deutlich, wie sich die Unterschiede in der Interpunktion auf die Interpretation der Sonette auswirken.
