The digital age demands new cognitive linguistic competencies including children’s narrative skills (Cappello & Siini2024). It also evokes questions of equity and inclusion involving children’s agentic creation of and participation ineducational commons (Cappello et al. 2024). Our government-funded research-project develops a mixed-methodsmethodology that joins the two fields and includes pedagogical classroom-factors for studying how aesthetic literacyevents (ALEs) affect children’s narratives and commons. There is currently no consistent body of research that joinsthe two fields (Olsson et al. 2023). Both fields call for classroom-level studies and quantitative methods (Dillon et al.2017; Nilholm 2021). Research on children’s narratives and commons is expanding, requiring further research on theaesthetic dimension of these (Pesco & Gagné 2017; Cappello et al. 2024). We draw on philosophical-aesthetical andcultural-cognitive theories (Bergson 1896/1988; Bruner 1991; Nelson 1996) to conceptualize how narratives,commons and pedagogical classroom-factors are mutually constituted in ALEs. Within a mixed-methods paradigm(Corr et al. 2020) we develop and field-test methodology - including ethnographic methods and standardized measures for narrative skills, commons-creation skills and pedagogical classroom-factors - in a purposively sampledgroup of 54 children aged 2-6. Formal ethical approval, informed consent from caregivers and educators, and negotiated consent from children were secured. Anonymization and secure data storage procedures were applied.We present results of reliability-tests, methodological reflections and data from a first round of field-testing a mixed-methods approach for studying how ALEs affect children’s narratives and commons. Researchers, practitioners andpolicymakers may use results to study and implement ALEs that stimulate children’s narratives and commons.aesthetic literacy events, methodology-development, mixed-methods, narrative, commons.
