This paper describes an effort to model students' changing knowledge state during skill acquisition. [...] Key Method As the student works, the tutor also maintains an estimate of the probability that the student has learned each of the rules in the ideal model, in a process calledknowledge tracing. The tutor presents an individualized sequence of exercises to the student based on these probability estimates until the student has ‘mastered’ each rule.Expand

Knowledge Tracing Models’ Predictive Performance when a Student Starts a Skill
Previous studies on the accuracy of knowledge tracing models have typically considered the performance of all student actions. However, this practice ignores the difference between students’ initial… Expand
Tutor Modeling vs . Student Modeling
The current paradigm in student modeling, Knowledge Tracing, has continued to show the power of its simplifying assumption of knowledge as a binary and monotonically increasing construct, the value… Expand
Investigating Knowledge Tracing Models using Simulated Students
Intelligent Tutoring Systems (ITS) are widely applied in K-12 education to help students to learn and master skills. Knowledge tracing algorithms are embedded in the tutors to keep track of what… Expand

TLDR
ModPFA was developed by adding the hinting parameter to the original PFA formula and has scoring procedure and knowledge level estimation for each student, and results have shown great improvement in terms of performance estimation in the ModPFA compared to PFA. Expand
Generalized Knowledge Tracing: A Constrained Framework for Learner Modeling
TLDR
It is argued that to be maximally applicable a learner model needs to adapt to student differences, rather than needing to be pre-parameterized with the level of each student's ability, to strengthen the applicability to learning technology. Expand
Modeling Student Knowledge: Cognitive Tutors in High School and College
TLDR
The role of student modeling in making the transition from the research lab to widespread classroom use is examined, university-based efforts to empirically validate student modeled in the ACT Programming Tutor are described, and a description of the key role that student modeling plays in formative evaluations of the Cognitive Algebra II Tutor is described.

Going Online: A simulated student approach for evaluating knowledge tracing in the context of mastery learning
Knowledge tracing algorithms are embedded in Intelligent Tutoring Systems (ITS) to keep track of students’ learning process. While knowledge tracing models have been extensively studied in offline… Expand
Predicting Individualized Learner Models Across Tutor Lessons
TLDR
It is found that best-fitting student parameters trained on previous lessons do not directly transfer to new lessons; however, one can effectively predict the student parameters for the new lesson by using features derived from prior lessons, and prior to tutor text-reading transaction data. Expand
Tutor Modeling Versus Student Modeling
TLDR
Harnessing the same simplifying assumption of learning used in student modeling, this model can be turned on its head to effectively tease out the tutor attributes causing learning and begin to optimize the tutor model to benefit the student model. Expand
Using Bayesian Networks to Manage Uncertainty in Student Modeling
TLDR
The basic mechanisms that allow Andes’ student models to soundly perform assessment and plan recognition, as well as the Bayesian network solutions to issues that arose in scaling up the model to a full-scale, field evaluated application are described. Expand

TLDR
Apparently, this transfer mechanism acts on declarative propositional representations of the production rules, suggesting that it is more similar to comprehension processes than to conventional practice mechanisms, or to Anderson’s learning principles. Expand
