    The general goal is to provide the technology required to build systems that can provide intelligent tutoring in IDEF (Integrated Computer Aided Manufacturing Definition Method) modeling. The following subject areas are covered: intelligent tutoring systems for systems analysis methodologies; IDEF tutor architecture and components; developing cognitive skills for IDEF modeling; experimental software; and PC based prototype

    Adaptive Layout for Interactive Documents

    This thesis presents a novel approach to create automated layouts for rich illustrative material that could adapt according to the screen size and contextual requirements. The adaption not only considers global layout but also deals with the content and layout adaptation of individual illustrations in the layout. An unique solution has been developed that integrates constraint-based and force-directed techniques to create adaptive grid-based and non-grid layouts. A set of annotation layouts are developed which adapt the annotated illustrations to match the contextual requirements over time

    Model-Based Systems Engineering Pilot Program at NASA Langley

    NASA Langley Research Center conducted a pilot program to evaluate the benefits of using a Model-Based Systems Engineering (MBSE) approach during the early phase of the Materials International Space Station Experiment-X (MISSE-X) project. The goal of the pilot was to leverage MBSE tools and methods, including the Systems Modeling Language (SysML), to understand the net gain of utilizing this approach on a moderate size flight project. The System Requirements Review (SRR) success criteria were used to guide the work products desired from the pilot. This paper discusses the pilot project implementation, provides SysML model examples, identifies lessons learned, and describes plans for further use on MBSE on MISSE-X

    Comprehension constitutes the main purpose of reading, one of the most important human skills. Furthermore, reading and therefore comprehension are perplexing procedures, that are built through the interaction of the cognitive functions. Comprehension occurs in a cognitive and metacognitve level. Meta-comprehension indeed, constitutes an important interpretive factor of learning, especially in the field of text comprehension. The present review study attempts to emphasizes and interpret a variety of research protocols, which have as an ultimate goal text comprehension evaluation and improvement in adult population. Implications for integrating different comprehension-monitoring experimental designs to improve text comprehension in adults are discussed

    Using Film as a Multimodal Text in the Language Classroom

    Film is a powerful medium for language acquisition; Not only does viewing films allow learners to experience language used in various real-life contexts, but the medium of film itself is a form of communication. Through the active viewing of films, students can explore how people with diverse backgrounds, accents, and cultures communicate using multiple modes such as gestures, images, and sounds. When learners are familiar with the techniques used by filmmakers to convey meaning, they can use the medium of film themselves to tell their stories and share their perspectives through filmmaking projects. Such projects can be collaborative and engaging and build on the four skills as well 21st century skills. This thesis establishes a theoretical foundation by introducing key theories related to the use of film for language learning and how they can be beneficial if implemented effectively. The author then examines teacher preparedness for implementing film viewing and filmmaking in the classroom, first by reviewing the literature of studies that have been done, then goes on to discuss the results and implications of original research conducted by the author of teachers and their experiences and perceptions of using film in their classrooms. The paper concludes with the lessons learned from the design and delivery of multiple iterations of a professional development workshop for educators interested in using film
