  • IntroductionAgent is needed when students are preparing to engage in an online debateIndividual contributions online debate worth 40%Defending open-ended evaluation criteria using CollabraAddressing implementation challenges in real-world situations

  • Approach to designing computer-based pedagogical agentsLimitations in the available methods for building models of open-ended debates, our approach: Theoretical framework Analysis techniques of interaction dataComputational model, i.e. system design.Computer implementation, e.g. MetaMuse

  • Dialogue analysis and modelling Analysing the interaction data for occurrences of categories of goals drawn from our theoretical frameworkPatterns of goals will be modelled as state transition networks
