A paperless classroom, when all materials required to complete a class are available in an electronic form, has been shown to have positive impacts on student and teacher motivation, engagement, productivity, and efficiency. Recent trends suggest that of all of the technological tools available, tablet PCs can support many aspects of a paperless…

Detecting the student internal state during learning is a key construct in educational environment and particularly in Intelligent Tutoring Systems (ITS). Students' uncertainty is of primary interest as it is deeply rooted in the process of knowledge construction. In this paper we propose a new sensor-based multimodal approach to model…

The need for emotional interaction has already influenced various disciplines and industries, and online museums represent a domain where providing emotional interactions could have a significant impact. Today, online museums lack the appropriate affective and hedonic values necessary to engage art enthusiasts on an emotional level. To address…

Since the days Internet traffic proliferated, measurement, monitoring and analysis of network traffic have been critical to not only the basic understanding of large networks, but also to seek improvements in resource management, traffic engineering and security. At the current times traffic in wireless local and wide area networks are facing…

The main goal of this research study was to develop a conceptual model for the design of public library websites for teens (TLWs) that would enable designers and librarians to create library websites that better suit teens' information needs and practices. It bridges a gap in the research literature between user interface design in human-computer…

In this thesis, we study the importance of background knowledge in relation extraction systems. We not only demonstrate the benefits of leveraging background knowledge to improve the systems' performance but also propose a principled framework that allows one to effectively incorporate knowledge into statistical machine learning models for…

The demands of an increasingly knowledge-based society and the dramatic advances in mobile phone technology are combining to spur the growth of mobile learning (mLearning). However, for mLearning to attain its full potential, it is essential to develop pedagogy and instructional design tailored to the needs of this new learning environment. At…

This dissertation bridges the fields of haptics, engineering, and education to realize some of the potential benefits haptic devices may have in Science, Technology, Engineering, and Math (STEM) education. Specifically, this dissertation demonstrates the development, implementation, and assessment of two haptic devices in engineering and math…

Natural Language Generation (NLG) is the process of generating natural language text from an input, which is a communicative goal and a database or knowledge base. Informally, the architecture of a standard NLG system consists of the following modules (Reiter and Dale, 2000): content determination, sentence planning (or microplanning) and surface…

With the advent of ubiquitous computing, interaction design has broadened its object of inquiry into how smart computational artifacts inconspicuously act in people's everyday lives. Although user-centered design approaches remains useful for exploring how people cope with interactive systems, they cannot explain how this new breed of…

The context for this work is two-agent team decision systems. An "agent" is an intelligent entity that can measure some aspect of its environment, process information and possibly influence the environment through its action. In a collaborative two-agent team decision system, the agents can be coupled by noisy or noiseless interactions…

The article aims to illuminate the character of Web 2.0 based on a reading of Martin Heidegger in order to provoke new epistemological questions about Web 2.0 and knowledge formation. The article applies the ontological grounds on which Heidegger described being-in-world and worldliness to the phenomenon of Web 2.0. The article states that Web 2.0…

It was just a generation ago that computers entered the workplace. Back then, they only "represented" the work we did, nothing else. But today, some sort of computing device is involved in how we play, how we communicate, how we get our news and of course, how we work. What this means is that today almost all aspects of our lives are "represented"…

The primary purpose of this study was to replicate and extend a study by Gravina, Austin, Schroedter, and Loewy (2008). A similar self-monitoring procedure, with the addition of self-monitoring accuracy training, was implemented to increase the percentage of observations in which participants worked in neutral postures. The accuracy training…

The significance of teaching the basics of engineering education in middle- and high-schools is generally acknowledged by policy makers, teachers and researchers in the U.S.A. as well as a number of developed and developing countries. Nevertheless, engineering topics are rarely covered by precollege curriculums. A key contributing factor is that…
