While simulations seem to be useful, we still need to understand how these environments can be designed to effectively promote student learning. The aim of the Learning Historian is to provide a richer environment to learners while they freely explore the behavior of a simulation. The basis of the Learning Historian is to record the history of the interaction with the simulation and allow this history to be replayed for review, sent with a message, used in a tutorial, or replayed as a series of variants to facilitate comparisons and explorations.

This project is sponsored in part by NSF via a NSF-CIRE initiative between ISR and North Carolina A&T, where Celestine Ntuen and his student Ben
Okoye have been conducting an evaluation of the simulation modules that will have historians added to them.
