This paper reviews literacy learning conducted in two laboratory preschools in Hong Kong and Canada, and examines the link between cultural values and educational practices. Both preschools maintain that a constructivist view of child learning underpins their practice. However, the author's experience in these two settings illustrates how similarities and differences are identified in the scope, focus, implementation strategies and learning outcomes of the activities observed. Reasons for these findings are explored from the perspectives of cultural values and societal beliefs in education of the East and the West, and how the constructivist ideology is espoused in these settings. Implications of this cross-cultural comparison on the issue of 'best practice' in early childhood education are discussed.
