Abstract: Systems and methods for dynamically assessing and providing feedback to a learner include displaying a set of assessment questions on a graphical user interface, obtaining a set of responses corresponding to the assessment questions, obtaining a set of diagnostic scoring rules including a set of diagnostic parameters corresponding to each assessment question and a response key, obtaining a set of learner-specific behavioral parameters, applying the set of diagnostic scoring rules to the set of responses to generate a learner response matrix, generating a learner attribute profile by applying as a set of probabilities of mastering each learning category to the learner response matrix, and estimating a learner response to a subsequent assessment question by applying a cognitive diagnostic model (CDM) or a Bayesian knowledge tracing (BKT) process to the learner attribute profile to the learner attribute profile.

Abstract: Exemplary data structures designed for log files of game/simulation-based educational assessments are described. An exemplary data structure may comprise at least one session element representing an assessee's participation in an educational assessment session; a session identification element identifying the educational assessment session represented by the session element; an assessee identification element identifying the assessee participating in the educational assessment session represented by the session element; an events element representing a collection of events occurring in the educational assessment session represented by the session element; an event element representing one event in the collection of events; an event time element indicting a time associated with the event; an event performer element indicating a performer of the event; an event target element indicating a target of the event; and an event result element representing a result of the event.
