Following Computer Aided Instruction systems, 2nd generation tutors are Model-Tracing Tutors (MTTs) (Anderson & Pelletier, 1991) which are intelligent tutoring systems that have been very successful at aiding student learning, but have not reached the level of performance of experienced human tutors (Anderson et al., 1995). To that end, this paper presents a new architecture called ATM ("Adding a Tutorial Model"), which is an extension to model-tracing, that allows these tutors to engage in a… Expand
Rule-based Cognitive Modeling and Model Tracing for Symbolization in a Math Story Problem Tutor
Intelligent Tutoring Systems (ITSs) are intended to help in tutoring students in specific domains, typically by improving their problem solving skills. An important aspect of such ITSs is the abilityExpand
Authoring Problem-Solving Tutors: A Comparison between ASTUS and CTAT
TLDR
This chapter presents a study performed to evaluate the strengths and weaknesses of ASTUS compared to the well-known Cognitive Tutor Authoring Tools (CTAT) framework and built a multi-column subtraction tutor (model and interface) with each framework. Expand
An Intelligent Tutoring System for the Accounting Cycle: Enhancing Textbook Homework with Artificial Intelligence
TLDR
An electronic tutoring system, developed using principles of artificial intelligence (AI), to help students learn the accounting cycle is described and it is shown that the tutor group’s test performance increased approximately 27% points, whereas the textbook group's test performance improved by only 8% points. Expand
Rule-based expert systems to support step-by-step guidance in algebraic problem solving: The case of the tutor PAT2Math
TLDR
This paper describes the expert system (ES) module of an Algebra ITS, called PAT2Math, and describes how it was reduced from O(nd) to O(d), where n is the number of rules in the knowledge base, by implementing some meta-rules that aim at inferring the operations students applied in order to produce a step. Expand
Decision-Making in Cognitive Tutoring Systems
TLDR
This chapter describes how some of this AI is put to work in artificial tutoring systems to reach decisions on when and how to intervene, and takes a particular interest in pursuing the path of “natural” AI for tutors systems, using human cognition as a model for artificial general intelligence. Expand
Teaching Algebraic Model Construction: A Tutoring System, Lessons Learned and an Evaluation
TLDR
This paper describes the lessons learned during the iterative development process of a short, intensive course in algebraic model construction, which combines human teaching with a tutoring system. Expand
Designing a Knowledge Representation Approach for the Generation of Pedagogical Interventions by MTTs
TLDR
This paper shows how Astus, as an MTT framework, strive to attain a higher level of automation when generating pedagogical interventions compared to other MTT frameworks such as TDK and CTAT's MTTs by designing a knowledge representation approach in which each type of knowledge unit has a clearly defined semantic on which the MTT’s pedag logical module can rely on. Expand
A Decision-Theoretic Tutor for Analogical Problem Solving
We describe a decision-theoretic tutor that helps students learn from Analogical Problem Solving (APS), i.e., from problem-solving activities that involve worked-out examples. This tutor incorporatesExpand
Computational Intelligence Approaches for Student/Tutor Modelling: A Review
  • S. Sani, T. N. M. Aris
  • Computer Science
  • 2014 5th International Conference on Intelligent Systems, Modelling and Simulation
  • 2014
TLDR
The aim of this paper is to investigate the most recent state of art in the development of the tutor model and student model of the intelligent tutoring systems. Expand
A Systematic Literature Review of Intelligent Tutoring Systems With Dialogue in Natural Language
TLDR
The results of this review reveal that most ITSs are directed toward science, technology, engineering, and mathematics (STEM) domains at the university level, and the majority of the selected ITSs implement the expectations and misconceptions tailored approach. Expand

Tutorial Dialog in an Equation Solving Intelligent Tutoring System
TLDR
Preliminary results using a very small sample size showed that E-tutor capabilities performed better than the control, and shows promising opportunities to improve learning performance by adding tutorial dialog capabilities to ITSs. Expand
Tutoring rules for guiding a case method dialogue
TLDR
This paper describes the rule-based formalism used by MYCIN-like programs, and argues that these programs are not sufficient in themselves as teaching tools, and claims that it is desirable to represent teaching expertise explicitly, using a flexible framework that makes it possible to easily modify tutorial strategies and communicate them to other researchers.

AutoTutor: A simulation of a human tutor
TLDR
This work has dissected the discourse and pedagogical strategies these unskilled tutors exhibit by analyzing approximately 100 hours of naturalistic tutoring sessions. Expand
Supporting Constructive Learning with a Feedback Planner
TLDR
This paper proposes a modular and reusable architecture for tutorial dialogue systems and discusses how a reactive planner in the context of this architecture can implement multi-turn tutorial strategies. Expand
Tutoring Techniques in Algebra
Although one-to-one tutoring has been regarded as the most effective method of teaching (Bloom, 1984), surprisingly little is understood about tutoring expertise. Much educational research focuses onExpand
Cognitive Tutors: Lessons Learned
TLDR
The 10-year history of tutor development based on the advanced computer tutoring (ACT) theory is reviewed, finding that a new system for developing and deploying tutors is being built to achieve the National Council of Teachers of Mathematics (NCTM) standards for high-school mathematics in an urban setting.

The Need for Tutorial Dialog to Support Self-Explanation
TLDR
An exploratory experiment with a tutor version that did not do any natural language processing, strongly suggested the need for natural language dialog, and students provided few free-form explanations in response to the tutor's prompts. Expand
Intelligent tutoring systems have forgotten the tutor: adding a cognitive model of human tutors
I propose that a more effective intelligent tutoring system (ITS) for the domain of algebra symbolization can be made by building a cognitive model of human tutors and incorporating that model intoExpand
Eye movements and algebra tutoring
TLDR
The possibilities for broadening the bandwidth of information available to a computer tutor by providing it access to a student's eye movements are investigated, and the conclusion is that an inductive support design is the better design for teaching algebra symbolization. Expand
