Pedagogy has undergone a paradigm shift since the focus changed from uni-directional transmission to collaborative construction of knowledge. The social constructivist approach calls for pedagogy to facilitate interaction between learners involved in collaborative problem solving of real life tasks. This paper describes a wikibased implementation of this approach (TransWiki) in the learning of translation. The paper examines issues that arise both from the perspective of the learner/user and the pedagogue and discusses solutions supported by the customization of the wiki system. User surveys and a case study indicate that the platform for collaboration is generally well received, but there is marked ambivalence with regard to the advantages of asynchronous collaboration through TransWiki over real-time face-to-face discussions. From the perspective of the instructor, the platform is seen as enabling scaffolding and providing a wealth of data that could inform pedagogy.
