Mieux vaut tard que jamais. J'ai ete frappe par les oeuvres de Sjolander. Par leur esprit vraiment moderne.

Die Wiederkehr des Vergangenen - Ende der Utopien?
The purpose of this licentiate thesis is to study the aspects of the teaching that enable students of younger ages to be engaged in algebraic work. Learning study has been used as the method to produce data. A research team consisting of two primary school teachers in mathematics and a teacher researcher worked collaboratively, designing interventions iteratively during the learning study process. In the design as well as analysis, Davydov's learning activity theory, Variation theory and Radford's definition of algebraic pattern generalizations have been used as theoretical starting points. The empirical data consists of 1 video-recorded interviews with eight students as well as transcriptions thereof; 2 video recordings of three research lessons; 3 lesson plans; 4 synopsis of video recordings of three research lessons; 5 transcriptions of parts of video recorded research lessons.
