Today’s challenges of climate change, managing global economies, city planning, and disease outbreaks are all examples of “complex systems.” Trends in weather, stock bubbles, traffic jams, and disease transmission are the occurrences from these challenges that result from many small causes combined. Extracting Salient Scenarios from Interaction Logs helps students understand the principles of complex systems by developing a new type of education technology to support their learning and participation in the multi-person immersive simulation. Because different principles surface depending on how each simulation unfolds, it can be difficult for teachers to adjust their lesson plans on the fly to highlight the principles that emerge. To address this challenge, ESSIL develops methods to create “automatic salient recaps,” to help learners and their teachers make better sense of simulations.  The recaps automatically generate a story of “what happened” to help students remember their experience. Teachers and other facilitators use these recaps and a discussion guide, to support productive learning conversations about the scientific principles incorporated in a simulation.

Connected Worlds is the project’s immersive simulation context. Connected Worlds is an embodied, multi-person ecology simulation at NYSCI, with pedagogical goals around sustainability and systems thinking. Using logs from groups of students interacting with Connected Worlds, ESSIL constructs selective personal recaps of their experience and has explanatory coherence (to enable their discussion of important interconnections in the simulation’s underlying model). Artificial Intelligence-based methods are developed to

1. identify salient changes in the state of the simulation during student interaction
2. construct qualitative models of causal chains that could have led to these changes

These qualitative models will be used to generate salient recaps and discussion guides, which will be provided to teachers whose classes are visiting NYSCI. The effectiveness of the innovation will be investigated by comparing visiting students’ conversations with and without ESSIL-generated discussion supports and by interrogating their resulting models of the Connected Worlds system through concept maps.

The recaps are developed for a large-scale immersive simulation installed at the New York Hall of Science (NYSCI), to improve thousands of daily visitors’ educational experience. The capabilities developed have widespread applicability because logs of student interactions are routinely produced by many educational systems.
