Investigated differences in collaborative problem solving activity between pairs of students working around a computer or with physical apparatus, and related differences to the development of scientific reasoning. 98 9-10 yr old students were placed into either same- or mixed-ability pairs according to individual pre-test performance on a scientific reasoning task. These pairs then worked on either a computer-simulation or a physical version of a chemical combination task. Results show that type of presentation mediated the nature and type of collaborative activity. Mixed-ability pairs working around the computer talked proportionally more about the task and management of the task, had proportionally more transactive discussions and used the record more productively than children working with the physical apparatus. Type of presentation also mediated learning. Students in same-ability pairs who worked with the physical apparatus improved significantly more than same-ability pairs who worked around the computer. It is concluded that these findings show the importance of tools for mediating collaborative activity and collaborative learning. (PsycINFO Database Record (c) 2007 APA, all rights reserved).
