Introduction to the special issue on generalisation from dialogical single case studies

Drawing on historical, theoretical and cultural knowledge, this introduction explains and justifies the importance of generalisation from dialogical single case studies. We clarify the meaning of dialogism and dialogicality, differentiate between single case studies and dialogical single case studies, identify the dynamic and ethical features of dialogical single case studies, and articulate the problem of generalisation as it pertains to this topic. We suggest that the question of generalisation ought to be viewed as an effort to resituate knowledge and its dialogical features, for example values, ethical standards or levels of engagement, in other dialogical single case studies.
