E-learning systems based on a conversational agent provide the basis of an intuitive, responsive, engaging interface for the online learner. This paper proposes an approach to intelligent intervention and strategic pedagogical design for improving student engagement when chatting with a conversational agent. First, we used previous conversational logs to detect and classify interaction behaviors of learners. And then we designed a set of strategies for intelligent intervention to improve

The interventions were observed to have the desired effect on behaviours associated with conversational engagement.
