Intelligent tutoring systems (ITSs) are computer programs that provide instruction adapted to the needs of individual students. Dialog communicate with human users by using natural language. This paper presents a systematic literature review address ITSs incorporate dialog and have been implemented in last twenty years. The found 33 focused on answering following five research questions. a) What language dialogue developed? b) is main purpose each system? c) pedagogical features teaching...

In recent years, recommender systems have been used as a solution to support tourists with recommendations oriented maximize the entertainment value of visiting tourist destination. However, this is not an easy task because many aspects need be considered make realistic recommendations: context destination visited, lack updated information about points interest, transport information, weather forecast, etc. The concerning must linked interests and constraints tourist. research, we present...

Data mining is known to have a potential for predicting user performance. However, there are few studies that explore its student behavior in procedural training environment. This paper presents collective model, which built from past logs. These logs first grouped into clusters. Then, an extended automaton created each cluster based on the sequences of events found The main objective this model predict actions new students improving tutoring feedback provided by intelligent system. proposed...

This article presents an investigation on the educational value of virtual worlds intended for acquisition procedural knowledge. takes as a case study laboratory biotechnology. A remarkable feature in this is automatic tutor that supervises student’s actions and provides tutoring feedback when it appropriate. The presented covers two different aspects system. First, analyzes impact world learning some concepts related to biotechnology practice; second, surveys students’ opinion by means...

This paper describes the preliminary results of an educational innovation project in which virtual world technologies have been used to build up a set laboratories oriented engineering studies. Focusing on architecture biotechnology laboratory created this project, we describe how will also be adopted other labs under construction, so that these can take advantage same benefits. Instead relying commercial software solution, with open source infrastructure named OpenSim. The limitations found...

Applying virtual reality (VR) in combination with intelligent tutoring systems (ITSs) is a promising approach to computer based learning and training. However, the classical structure of ITSs has not been conceived deal new sources information interaction provided by VR environments. The resulting structures combining both technologies often renounce traditional modular separation pursuit increasing efficiency, but making very difficult reusing their components. In this paper it described...

This paper addresses the challenge of integrating a dialog system with an ITS created for supporting procedural training in 3D virtual environment. To this end, we first describe desired features to be provided students such system. Then, explain some technical issues our proposal as architecture; design manager; and construction answers students' questions by leveraging ontology related world. Next, present pilot study validate approach. In study, utilized prototype that encompasses...
