Résumé : The question that the authors of this article are collectively concerned with is as follows: how is it possible to protect children without disempowering them? To this end, the authors work to change adultcentric scholarly and social norms that justify rationales that marginalize children. The article begins with a theoretical overview of childism, in its transformative sense, with special attention to how childism relates to intersectional analyses. In doing so, age is highlighted as an axis of marginalization with reference to adultcentrism. After that, the centrality of analyzing and problematizing adultism in educational research and practice is discussed. The discussion is followed by a presentation of the published results of ‘The Adultcentrism Scale’ research tool developed at the University of Bergamo and the University of LUMSA-Rome. The research tool is used to evaluate the presence of adultcentric bias in adults in relation to children and can be helpful to understanding the psychological dimensions of educational relationships. Finally, the conclusion offers suggestions for how the research tool might be a useful example to raise awareness of adultcentric bias, promoting reflections that can lead to age-inclusive transformations. Overall, then, the article initiates a pertinent dialogue for advancing children’s participation rights in Nordic research and society.
