Abstract: | Collaborative learning with cases characteristically involves discussing and developing shared explanations. We investigated
the argumentation scheme which learners use in constructing shared explanations over evidence. We observed medical students
attempting to explain how a judge had arrived at his verdict in a case of medical negligence. The students were learning within
a virtual learning environment and their communication was computer mediated. We identify the dialogue type that these learners
construct and show that their argumentation conforms with an abductive form of argumentation scheme (‘inference to the best
explanation’). We also assessed the students’ learning and propose that it is related to particular features of this argumentation
scheme. |
