The role of instructors as users/authors of ITS authoring tools is very important for the effectiveness of the produced ITSs. In order for authoring tools to benefit the most from the involvement of instructors, they should provide individualised feedback to them throughout the ITS’s life cycle. In most cases the addition of an instructor modelling(More)
Authoring tools for Intelligent Tutoring Systems (ITSs) are meant to provide environments where instructors may author their own ITSs in varying domains. In this way, painful constructions of ITSs, which are not reusable, may be avoided. However, the construction of an authoring tool is associated with many problems, such as the generality of the techniques(More)
This paper describes the development of a web-based authoring tool for Intelligent Tutoring Systems and focuses on its instructor modelling capabilities. The tool is called WEAR and aims to be useful to teachers and students of domains that make use of algebraic equations. Specifically, the tool provides assistance to human teachers while they are(More)
WEAR is a Web-based authoring tool for the construction of Intelligent Tutoring Systems (ITSs) in Algebra-related domains, such as physics, economics, chemistry, etc. In WEAR’s authoring environment instructors are able to construct problems and tests and also build adaptive electronic textbooks. In return, WEAR generates a learning environment in which(More)
WEAR is a Web-based authoring tool for Intelligent Tutoring Systems in Algebra related domains. Apart from modelling the student which is a common practice in almost all ITSs and ITS authoring tools, WEAR deals also with modelling the other class of its users: the instructors. Student and instructor models in WEAR interact with each other by exchanging(More)
This paper reports on an empirical study concerning the use of LEGO Mindstorms Robotics kit as an instructional tool in technical and vocational secondary education. In particular, a robot car was developed and programmed in order to be utilized in teaching classes in the field of Mechanical Engineering. The paper describes the rationale for that(More)
This paper describes the evaluation of a speech-driven cartoon agent that has been embodied in the interface of a Web-based Intelligent Tutoring Systems (ITSs) authoring tool. The agent is mainly used in the student interface of the ITSs that are produced by the authoring tool and represents either a student or an instructor. The agent was evaluated during(More)
