Turbinia-Vyasa is an instructional system that trains operators in diagnostic problem solving in the domain of marine power plants. It is comprised of a steam power plant simulator and an intelligent tutoring system. The simulator, Turbinia, is based on a hierarchical representation of subsystems, components, and primitives together with necessary physical and logical linkages among them. Vyasa...

In order to develop tutoring systems that strike a better balance between system control and student control, or systems that provide guidance and feedback in order to help students learn help-seeking skills, we need a better understanding of (actual and ideal) help seeking. In this paper, we take modest steps toward this goal: First, we continue to assess students help-seeking behaviour in the...

The current paradigm in student modeling has continued to show the power of its simplifying assumption of knowledge as a binary and monotonically increasing construct, the value of which directly causes the outcome of student answers to questions. Recent efforts have focused on optimizing the prediction accuracy of responses to questions using student models. Incorporating individual student pa...

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 of which directly causes the outcome of student answers to questions. Recent efforts have focused on optimizing the prediction accuracy of responses to questions using student models. Incorporating i...

The MATHESIS Algebra Tutor [1] is a model-tracing tutor for expanding and factoring algebraic expressions. The tutor teaches a breadth of 16 top-level math skills (operations): monomial multiplication, division and power, monomial-polynomial and polynomial-polynomial multiplication, parentheses elimination, collect like terms, identities (square of sum and difference, product of sum-difference,...

With the advancements in mobile technology and its utilization in every facet of life, mobile popularity has enhanced exponentially. The biggest constraint in the utility of mobile devices is that they are powered with batteries. Optimizing mobile’s size and weight is always the choice of designer, which led limited size and capacity of battery used in mobile phone. In this paper analysis of th...

We present an automated detector that can predict a student’s future performance on a transfer post-test, a post-test involving related but different skills than the skills studied in the tutoring system, within an Intelligent Tutoring System for College Genetics. We show that this detector predicts transfer better than Bayesian Knowledge Tracing, a measure of student learning in intelligent tu...

This article describes an intelligent, integrated, web-based school for tutoring expansion and factoring of algebraic expressions. It provides full support for the management of the usual teaching tasks in a traditional school: Student and teacher registration, creation and management of classes and test papers, individualized assignment of exercises, intelligent step by step guidance in solvin...
