This thesis focuses on four different aspects of history teachers’ comprehensiveunderstanding of the school subject history. More specifically, the aim is tostudy the comprehension of the subject as perceived by individual historyteachers. Special emphasis is placed on identifying the concepts of the field ofhistory that are central to the teachers’ understanding of the school subject history.The first aspect studied is the teachers’ biographical changes. In a life historyperspective it seems as if the teachers’ subject conception changes from anunproblematic and tentative approach to a more complex and confident understandingof the subject. The second aspect treated is the rationale behind theirgrasp of the purpose and content of the subject. Three major positions areidentified, namely educational (bildung) orientation, critical orientation, andidentity orientation.The third aspect studied is the teachers’ interpretation of a curriculumnew to them. The teachers placed the curriculum in the field of tension betweenan education policy position, emphasizing more precise knowledge, onthe one hand, and a history science position, emphasizing concepts of historicalconsciousness. The fourth aspect studied is five different conceptual tools displayedin the teachers’ remarks on having completed the teaching of a newcourse. These are termed ‘history as narrative’, ‘history as time-space’, ‘historyas explanation’, ‘history as perspective taking’, and ‘history as skills’At the general level the study shows not only that subject conception is ofimportance to the teachers’ understanding of their obligation as teachers of historybut also how it is formed and constantly transformed by many differentfactors. In this process it is clear that the concepts used by the teachers, althoughvariously defined, can be seen as specific to the school subject historyand essential to the construction of history as a school subject. / Vad är syftet med skolämnet historia och vad ska det innehålla? Det här är en doktorsavhandling där fokus sätts på lärares förståelse av skolämnet historia. Mer precist avgränsas syftet till att undersöka ämnesförståelsen hos nu verksamma historielärare. Särskild vikt läggs vid att identifiera centrala begrepp i lärarnas ämnesförståelse. Undersökningen bygger både på enkäter och intervjuer och tar sin utgångspunkt i fyra olika aspekter av historielärarnas ämnesförståelse som redovisas i separata studier. Den första aspekten är ämnesbiografisk och tar fasta på de faktorer lärarna menar har påverkat utvecklingen av deras ämnesförståelse. Den andra aspekten har sitt fokus på lärarnas förståelse av historieämnets övergripande syfte och innehåll. Den tredje aspekten handlar om hur lärarna tolkar inriktningen och innehållet i den nya ämnesplan som infördes i gymnasieskolan 2011. Den avslutande aspekten fokuserar på de ämnesredskap som blir synliga i de utsagor lärarna gör om innehållet i gymnasieskolans kurs Historia 1b.

The thesis focuses on how students learn history in the classroom, more precisely on their possibilities and difficulties in developing competence in the school subject of history. There is a particular emphasis on how they explain and understand historical processes and concepts within the subject of history. Participants are students of different grades, 8–19 years old. The purpose of the study is to explore how students learn history in concrete learning situations and my focus is on the types of knowledge students understand, learn, develop and use in comparison with what they are expected to learn.  This is done based on three fundamental and well-established principles of learning. To examine what kinds of knowledge students need I use three main types of knowledge: declarative content knowledge (facts and concepts), procedural knowledge (knowledge about how to do things) and self-regulatory knowledge (knowledge about how to regulate our memory, thought and learning). I also use concepts and insights from systemic functional linguistics (SFL) in order to explain why the students use language and communicate the way they do. The thesis shows that history is challenging for young students. Young students have difficulties with complex and abstract concepts in history as they treat concepts as facts. Older, more competent, students use concepts on a more abstract level and use different kinds of linguistic resources when formulating explanations of higher complexity, more similar to the way explanations in the domain of history are commonly written. The youngest students and some of the older students lacked factual knowledge, concept knowledge, domain specific self-regulatory knowledge and linguistic resources. Declarative content knowledge and facts are more important and more difficult for young students to understand, develop, organize and learn than previous scholars have shown empirically. Students’ abilities to understand facts and ideas in the context of a conceptual framework and to organize and structure facts with the help of concepts at different level of abstraction (conceptual understanding) are crucial. Students also need linguistic resources, both lexical knowledge and knowledge of text structures. Language is crucial both in the process of acquiring knowledge and in the process of communication. In the learning process, teaching is crucial, since individual students’ potential to develop competence depend on the potential of the teacher to discover and engage their preconceptions and arrange for learning in a way that give students the kind of knowledge they need.

This thesis focuses on four different aspects of history teachers’ comprehensive understanding of the school subject history. More specifically, the aim is to study the comprehension of the subject as perceived by individual history teachers. Special emphasis is placed on identifying the concepts of the field of history that are central to the teachers’ understanding of the school subject history.           The first aspect studied is the teachers’ biographical changes. In a life history perspective it seems as if the teachers’ subject conception changes from an unproblematic and tentative approach to a more complex and confident understanding of the subject. The second aspect treated is the rationale behind their grasp of the purpose and content of the subject. Three major positions are identified, namely educational (bildung) orientation, critical orientation, and identity orientation.           The third aspect studied is the teachers’ interpretation of a curriculum new to them. The teachers placed the curriculum in the field of tension between an education policy position, emphasizing more precise knowledge, on the one hand, and a history science position, emphasizing concepts of historical consciousness.

In this process it is clear that the concepts used by the teachers, although variously defined, can be seen as specific to the school subject history and essential to the construction of history as a school subject. / Baksidestex: Vad är syftet med skolämnet historia?
