Teaching and research in physiology encompass increasingly complex notions of the system under study. Computer modeling fosters understanding by extending the ability to formulate, test, and evaluate hypotheses about the system, and to describe experimental data. The exploration of the model system's behavior serves teaching and investigation in…

Describes a computer-aided tracking system for recording and analyzing the location pattern of teachers in the classroom. The technique will enable researchers to monitor teacher classroom mobility and to design correlational and time-series experiments. The results could lead to a better understanding of the nonverbal teaching-learning process.…

Examines issues related to real-world applications of higher education planning models, describing four different models as representative examples of the model spectrum. Also reviews situations in which qualitative considerations relegate the use of models to a low priority and situations in which information generated by models may be misused.…

This proceedings from the 2003 Symposium on Applications and the Internet (SAINT) contains papers from sessions on: (1) mobile Internet, including a target-driven cache replacement policy, context-awareness for service discovery, and XML transformation; (2) collaboration technology I, including human-network-based filtering, virtual collaboration…

Points out differences between the "instructional design" and "authoring" approaches to creating courses and courseware for computer-assisted instruction (CAI). Describes models and procedures for designing effective CAI packages. (Author/RW)

Identifies design variables directly related to the development of computer-based instruction (CBI) and shows how those variables can be applied in the actual development of a course. The design is for a computer literacy course concerned with both content and student attitudes about that content. (Author)

Examines traditional and interactive models that have emerged in information retrieval (IR), and proposes an interactive IR model based on different levels in the interactive processes. Analyzes strengths and weaknesses of the traditional model. Concludes with general remarks on the state of IR interaction research. (Author/AEF)

Design considerations for speech training systems include the types of information about speech to be used in training, whether acoustic or physiologic; and the use of models of speech production, whether partially perceptual and partially knowledge-based or explicit data-based models. A taxonomy of speech training systems is presented.…

The paper describes dynamic orometric instrumentation and procedures developed to measure, display, and guide changes in vowel and consonant production through visual articulatory modeling and feedback routines. Sensors are placed in the mouth to detect tongue shapes, positions, and actions during speech of hearing-impaired talkers, and online…

Discusses the design of computer applications, focusing on understanding design representations--what makes design representations work, and how, in different contexts. Examines the place of various types of representation (e.g., formal notations, models, prototypes, scenarios, and mock-ups) in design and the role of formalisms and representations…

Compares traditional mathematical models with computer simulations. Shows the strengths and flexibility of algorithmic computational simulations through a program designed to investigate and extend understanding in one of the most enduring questions in social choice research. Discusses solutions to this problem from each approach--analytic and…

The model presented in this paper is directed toward the improvement of the individualized instructional process by providing student achievement profiles, diagnostic reports, and suggested instructional prescriptions. (Author)

Because increased need for child protective services exceeded the Texas Department of Human Services' capacity for timely response, a 2-year Case Decision Project was implemented with the aim of applying automation to parts of the case investigation process. The project produced a Case Investigation Decision Support System with two sections: a…

The applications of a recently developed computer program for microcomputers in developing models in an institutional research environment are considered. The VISICALC program requires no user programming skills, is available for all major brands of microcomputers, and provides for easy exchange of information between users of different computing…

The SPADE theory, which uses linguistic formalisms to model the planning and debugging processes of computer programming, was simultaneously developed and tested in three separate contexts--computer uses in education, automatic programming (a traditional artificial intelligence arena), and protocol analysis (the domain of information processing…
