Efficient language learning is one of the keys to social inclusion. In this paper we present some work aiming at creating a virtual language tutor. The ambition is to create a tutor that can be engaged in many aspects of language learning from detailed pronunciation training to conversational practice. Some of the crucial components of such a system are described. An initial implementation of a...

We have been developing an Intelligent Tutoring System to teach students to analyze and debug C++ programs for semantic and run-time errors. In this tutor, we have used Model-Based Reasoning for domain modeling and explanation generation. In addition, we plan to use it for program animation. In this paper, we will present our design of the tutor, and results from evaluating one instance of the ...

In this work is proposed that an adaptation tool that is for the automatic generation and personalization of courses of a general-purpose LCMS that is named A Tutor. A Tutor is a Learning Content Management System. The architecture of the adaptation tool that allows a personalized sequencing of LOs in A Tutor for the learner’s learning goals, learning styles and cognitive state is presented.

ion/specification relations Abstract:instance (instance:abstract): S2 instantiates the abstraction stated by S1, or S2 abstracts over the information presented by S1. Tutor: How can the acceleration be 0 if there are forces on it? Student: The sum of the forces equal 0 for there to be no acceleration. Tutor: That’s exactly right. The weight and the normal force are (in this case) equal and oppo...

In this paper, we use sensor-free affect detection [4] and a discovery with models approach to explore the relationship between affect occurring over varying durations and learning outcomes among students using Cognitive Tutor Algebra. Researchers have suggested that the affective state of confusion can have positive effects on learning as long as students are able to resolve their confusion [1...

We have developed a prototype web-based homework environment (Homework Tutor) for delivering a physics homework assignment. The prototype provides students with feedback, incentives and interactivity while addressing known difficulties of the topic chosen. The questions are provided in an inquiry-based format. Students can manipulate the different physical parameters before answering the questi...

Based on the research of [Stil 1998] [Maurer 1992] [Lennon 1994] [Elliot 1995] [Colbourn 1995] [Reeves 1997] [Lugner 1997], the application of an expert system as an interactive multimedia knowledge module with explanation features named Virtual Tutor (VT) was developed. For students, the individual dialogue based session with the VT, provides the possibility to apply the knowledge acquired in ...

Problem-based learning (PBL) is a teaching and learning method designed to develop clinical reasoning skills. Tutor performance in PBL affects both the process and outcome of student learning. In this study, we investigated the factors that influence the evaluation by undergraduate students on the performance of tutors in medical education. From April 2009 to February 2010, 49 PBL sessions were...
