The Extensible Problem-Specific Tutor (xPST): Evaluation of an API for Tutoring on Existing Interfaces
نویسندگان
چکیده
The Extensible Problem-Specific Tutor (xPST) system was created to facilitate the creation of intelligent tutoring systems (ITSs) on existing software and web-based interfaces. This research introduces xPST and describes an exploration of the ease of authoring an xPST tutor for three web-based tasks. Participants demonstrated a quick learning curve and alternated their attentional focus regularly among the three components of the xPST authoring system.

Easy Authoring of Intelligent Tutoring Systems for Synthetic Environments
We describe how the Extensible Problem Specific Tutor (xPST), an open source engine for intelligent tutoring systems, has been adapted to provide training within game-engine based synthetic environments. We have designed a web-based tutor-authoring tool and have conducted a study that shows that xPST can be used by authors with minimal programming experience to create tutors for 3D game environ...
متن کاملIntelligent Tutoring System Authoring Tools for Non-Programmers
An intelligent tutoring system (ITS) is a software application that tries to replicate the performance of a human tutor by supporting the theory of “learning by doing” and providing customized instruction to a student while performing a task within a problem domain such as mathematics, medical diagnosis, or even game play. ITSs have been shown to improve the performance of a student in wide ran...
متن کاملExpansion of the xPST Framework to Enable Non-programmers to Create Intelligent Tutoring Systems in 3D Game Environments
Our previous work has demonstrated that the Extensible Problem Specific Tutor (xPST) framework lowers the bar for nonprogrammers to author model tracing intelligent tutoring systems (ITSs) on top of existing software and websites. In this work we extend xPST to enable authoring of tutors in 3D games. This process differs substantially from authoring tutors for traditional GUI software in terms ...
متن کاملFrom SDK to xPST: A New Way to Overlay a Tutor on Existing Software
Our past work has investigated the use of the Cognitive Model Software Development Kit (SDK) for creating the cognitive models that underlie model-tracing Cognitive Tutors. Though successful at increasing the number of people who could author such a cognitive model, for certain kinds of situations the Cognitive Model SDK proved cumbersome. The present work discusses a new authoring system, xPST...
متن کاملEvaluation of Two Intelligent Tutoring System Authoring Tool Paradigms : Graphical User Interface - Based and Text - Based
We describe an evaluation of two intelligent tutoring system authoring tool paradigms, graphical user interface-based and text-based by taking the examples of CTAT and xPST respectively, in two domains, statistics and geometry. We conducted a study with 16 tutor-authors divided into 2 groups (programmers and non-programmers). Our results showed that the GUI-based approach, aided by the visualiz...
