Purpose: This study aims to capture children's interpretation of holistic well-being within Irish primary schools and add to the development of a comprehensive systems-informed positive education model. Design/methodology/approach: This study utilized visual participatory research methods, including PhotoVoice and one-on-one interviews, to assess children's (n = 16) well-being, guided by Von Unger's comprehensive seven-step framework. Data analysis was anchored within grounded theory, beginning with data collection, initial coding, focused coding and culminating in identifying themes and subthemes. Data were interpreted using the mosaic approach by integrating visual and verbal data. Findings: This analysis uncovered three primary themes that affect student well-being: relationships, space and physical environment and learning and curriculum, each with detailed subthemes. For instance, student--teacher relationships, peer relationships, safety, learning spaces, the creative curriculum including arts and music and the experiential richness of outdoor learning are crucial to students' educational growth and well-being. These aspects are seen as interconnected, shaping a holistic educational experience beyond academic learning to encompass students' comprehensive well-being. The students' narratives demonstrated that learning is not merely an academic exercise but a vital component of their well-being. Originality/value: This study significantly departs from traditional educational research by advocating for a dynamic, action-oriented understanding of "well-being." It challenges the static, possessive interpretations of well-being and introduces the concept of well-being as a fluid and ever-evolving process. This reconceptualization positions well-being as a complex construct, influenced by an intricate web of relationships, spanning human and non-human interactions, organizational and environmental structures, personal desires, behavioral practices and broader societal and cultural frameworks.
