“…It only argues that the findings generated from different approaches reach different goals (Grønmo, 2019). The findings generated from the “decomposition approach” successfully present the profiles of children's learning and development outcomes from different perspectives, reveal children's transition difficulties and challenges, and identify the diverse factors relevant to school transition, but they could hardly explain the complexities and dynamics of child development during the transition to school (Hedegaard, 2019; Vygotsky, 1997a; Winther‐Lindqvist, 2021; Wortham et al, 2021). In other words, by using the “decomposition approach”, the evidences on the surface (such as what achievement children obtained, and what difficulties children encounter) could be captured, but the mechanisms underlying the surface (such as how children achieve, and why the difficulties appear) could hardly be explained (Fragkiadaki et al, 2021; Ma et al, 2022).…”
