Development of Group Understanding via the Construction of Physical and Technological Artifacts

摘要: The analyses reported in this chapter analyzed the development of group understanding along dimensions domain and intersubjectivity based on artifacts that a student constructed during learning. In terms knowledge development, identified progression four circuit understandings, showing group’s electrical circuits became more sophisticated over time as considered additional ways to light bulb(s). understandings also differed extent which they were interactively constructed, so some mainly by pooling individual ideas while others or less co-constructed process collaborative artifact construction.
