A generic architecture for interactive intelligent tutoring systems

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 07/06/2001.This research is focused on developing a generic intelligent architecture for an interactive tutoring system. A review of the literature in the areas of instructional theories, cognitive and social views of learning, intelligent tutoring systems development methodologies, and knowledge representation methods was conducted. As a result, a generic ITS development architecture (GeNisa) has been proposed, which combines the features of knowledge base systems (KBS) with object-oriented methodology. The GeNisa architecture consists of the following components: a tutorial events communication module, which encapsulates the interactive processes and other independent computations between different components; a software design toolkit; and an autonomous knowledge acquisition from a probabilistic knowledge base. A graphical application development environment includes tools to support application development, and learning environments and which use a case scenario as a basis for instruction. The generic architecture is designed to support client-side execution in a Web browser environment, and further testing will show that it can disseminate applications over the World Wide Web. Such an architecture can be adapted to different teaching styles and domains, and reusing instructional materials automatically can reduce the effort of the courseware developer (hence cost and time) in authoring new materials. GeNisa was implemented using Java scripts, and subsequently evaluated at various commercial and academic organisations. Parameters chosen for the evaluation include quality of courseware, relevancy of case scenarios, portability to other platforms, ease of use, content, user-friendliness, screen display, clarity, topic interest, and overall satisfaction with GeNisa. In general, the evaluation focused on the novel characteristics and performances of the GeNisa architecture in comparison with other ITS and the results obtained are discussed and analysed. On the basis of the experience gained during the literature research and GeNisa development and evaluation. a generic methodology for ITS development is proposed as well as the requirements for the further development of ITS tools. Finally, conclusions are drawn and areas for further research are identified

Examining Motivational Feedback For Sensor-Free Detected Frustration Within Game-Based Learning

Social interactions, decision-making, perceptions, and learning are all influenced by affect. Frustration, anxiety, and fear in particular can draw cognitive resources away from successful task completion, causing the learner to focus on the source of the emotion instead. Serious games offer an ideal environment to investigate how feedback influences student affect and learning outcomes, particularly when feedback is delivered via computer system detection. This dissertation discusses the results of an experiment run in September 2015 to investigate which motivational feedback condition yields the most significant correlation to positive learning gains when a computer system intelligently generates and delivers feedback based on the detection of frustration while participants played the serious video game, vMedic, a combat casualty care simulation which includes triage tasks. Of the three motivational feedback conditions examined (self-efficacy, social-identity, and control-value), the self-efficacy motivational feedback interventions yielded positive, statistically significant learning gains when compared to the social identity and control-value feedback conditions, as well as the non-motivational feedback control condition, and the no feedback control condition

Google Glass App for Displaying ASL Videos for Deaf Children – The Preliminary Race

Glass Vision 3D is a grant-funded project focused on the goal of developing and researching the feasibility & usability of a Google Glass app that will allow young Deaf children to look at an object in the classroom and see an augmented reality projection that displays an American Sign Language (ASL) related video. Session will show the system (Glass app) that was developed and summarize feedback gathered during focus-group testing of the prototype

CIB International Conference 2014: W55/65/89/92/96/102/117 & TG72/74/81/83 Construction in a changing world: Book of Abstracts

It is no exaggeration to say that CIB is the world's foremost platform for international cooperation and information exchange in the area of building and construction research and innovation. What takes place at CIB events is the very essence of CIB's raison d'être and, outside the triennial CIB Congress, an unprecedented number of CIB working commissions and task groups are represented at this Conference and we have worked to facilitate interaction with a rich mix of specialist streams, opportunities for informal networking and a series of challenging keynotes. With its focus of “Construction in a Changing World”, the Conference provides a forum for researchers worldwide to debate and exchange ideas and experiences on a broad range of issues. Driven by technology innovation, demographic growth, environmental change, a new economic order and a strong undercurrent of social and political desire for change, the world is changing quickly. Construction doesn’t exist in isolation and, in a fast-changing world, the sector has the vital role of providing the requisite built environment to meet the challenges presented by these changes. In order to deliver value, maintain competitiveness and address the needs of society, the construction industry will need to develop its capabilities for managing innovation and technical change. The Conference will bring together resources and knowledge across different fields, technologies and disciplines to deal with the major challenges that construction professionals will be confronted with in the coming years
