This chapter reports the doctoral study Engelsk i grunnskolen: Mål og innhold (Simensen, 1988a), which includes three investigations central to the field of English didactics. The overall aim of the study was to produce knowledge about the aims and content of the English school subject in compulsory school. One central focus was to investigate to what extent there was agreement over time between ideas in selected academic disciplines, “parent disciplines”, and ideas in the school subject, as reflected in curricula, assessment documents and adapted readers as teaching materials.
