Learning analytics research has used both knowledge engineering and machine learning methods to model student behaviors within the context of digital learning environments. In this paper, we compare these two approaches, as well as a hybrid approach combining the two types of methods. We illustrate the strengths of each approach in the context of…

This paper describes a narrative-based interactive learning environment which aims to elucidate reasoning using interactive scenarios that may be used in training novices in decision-making. Its design is based on an approach to generating narrative from knowledge that has been modelled in specific decision/reasoning domains. The approach uses a…

Discussion of dynamic modeling focuses on the development of a new modeling tool called Model-It which provides intentionally designed scaffolding for learners, enabling them to build and test dynamic models of complex systems using object-oriented and qualitative techniques. Classroom testing with high school students is described. (Author/LRW)
