This paper reports the findings of a predominantly qualitative study that explored the effects of the practice of Philosophy for Children on pupils’ affective engagement.[1] From its conception, the practice of P4C has been linked to the development of caring and collaborative thinking and the study aimed to closely consider that relationship. An appropriate self-designed P4C program was implemented with 75 Year 9 pupils of Religious Education at an independent secondary school in the United Kingdom. An interpretive research approach was (...) taken and thematic analysis was appropriated to analyse the data. Findings supported the claims of previous research that P4C can foster affective engagement in many pupils, particularly those pupils who find emotional expression and interpersonal interactions challenging. A tentative conclusion reached supposes that P4C has the potential to contribute to the affective engagement of pupils, but with the recommendation that implementing a P4C program must be executed carefully and with the mindfulness that it may not have the same potential or usefulness for all pupils universally.
