Elevers lärande i argumentativa diskussioner om hållbar utveckling

The overall ambition with this thesis is to develop knowledge about students’ learning, especially with regard to process and content, when they participate in argumentation. Students’ learning is investigated through in situ studies of classroom practices. The theoretical point of departure is a pragmatic perspective in which learning is understood and investigated in terms of concrete actions. The empirical material consists of video recorded lessons at secondary and upper secondary schools in Sweden. The content of the lessons is argumentative discussions about sustainable development and socioscientific issues. In the first study, the functions that teachers’ actions have for students’ learning processes are investigated using Epistemological Move Analysis. In the second study, an approach is developed and illustrated that facilitates investigations into students’ learning processes in terms of knowledge content and argument construction in argumentation. The method, called Transactional Argumentation Analysis, combines a pragmatic perspective of learning with an argument analysis based on Toulmin’s Argument Pattern. In the third study, the functions that knowledge have when used by students in argumentative discussions are examined. The fourth study investigates the role of peers for students’ learning and how students influence the argumentation at a collective level. Here Transactional Argumentation Analysis is developed further in order to facilitate investigations of the dynamic interplay between the intra-personal and the inter-personal dimensions of learning and the result of this interplay in terms of the knowledge content and arguments that are constructed. The thesis shows how students’ learning can be investigated through in situ studies of educational practices. The methodological contribution of the thesis consists of the development and further elaboration of Transactional Argumentation Analysis. The thesis also contributes with substantial knowledge about students’ learning processes with regard to knowledge content and argument construction when participating in argumentation. Another contribution concerns the functions of knowledge when used by students in argumentation. Finally, the studies show how peers and teachers influence students’ learning, and how students contribute to the shared argumentation in the classroom.
