Digital portfolios offer a view on various childhood environments with their daily activities and experiences, relationships, samples of children's work and festive moments. The publication presents an action research study, in which teachers were challenged and encouraged to utilize digital portfolios to collaboratively share and evaluate the quality of childhood education. Developing digital portfolios required consideration of several design and implementation issues. What are the purposes of digital portfolios in childhood learning environments? What kind of support teachers need for the evolvement of ICT capabilities? How does kindergarten or school culture frame portfolio development and use? How does ethical considerations affect portfolio sharing on the web?
