Research over the past 15 years concerning parametric and nonparametric statistics and 10 recently developed nonparametric techniques for testing interactions in experimental design are reviewed. The new nonparametric techniques are robust, powerful, versatile, and easy to compute. A fabricated dataset is used to illustrate the technique. (TJH)

Provides an overview of technology solutions for young children who have developmental concerns. Discusses the rationale for developmentally appropriate assistive technology and the use of high-tech computer-based solutions. Issues related to selecting appropriate hardware and software applications and a review of play-based software options are…

Focuses on computer systems that support groups who complete tasks together despite separations in space, time, or variations in team size. Reviews the literature on the history of the technology, application packages, case histories, and current research, and includes a synopsis of activity in academic and commercial institutions. Contains 217…

Using survey data, the authors examined the relationship between intensity (as opposed to duration) of a technology-focused professional development program and specific participant characteristics in predicting successful outcomes. The four participant characteristics chosen were: teachers' feelings of preparedness to support student technology…

As the frequency with which Classroom Response Systems (CRSs) are used is increasing, it becomes more and more important to define the affordances and limitations of these tools. Currently existing literature is largely either anecdotal or focuses on comparing CRS and non-CRS environments that are unequal in other aspects as well. In addition, the…

This report, profusely illustrated with color photographs and other graphics, elaborates on the Department of Energy (DOE) research program in High Performance Computing and Communications (HPCC). The DOE is one of seven agency programs within the Federal Research and Development Program working on HPCC. The DOE HPCC program emphasizes research in…

This report examines statewide planning and budgeting for educational technology in the 15 states covered by the Southern Regional Education Board (SREB), with a focus on state-level expenditures for telecommunications networks, microcomputers, software, and other technology. Capsule descriptions of each state's current activities are provided,…

This paper provides an idea of how to improve computer-assisted instruction effectiveness by incorporating teachers' images and voices into computers. Efforts to increase students' motivations by improving computer-assisted instruction feedback systems through the use of arcade-style video games and animation have proven to be ineffective and…

Intended to stimulate discussion rather than present solutions, this report summarizes how digital technology applies to preservation problems beyond the preservation of print materials. Specifically it describes the problems new kinds of media such as audio and videotape and computer disks pose to librarians and archivists in terms of long-term…

This paper examines how visual information strategies may be used to facilitate the development of mental models. Topics covered include: definition of mental models; mental models and visual information; mental modeling concepts; power of modeling, including examples related to physical science, mathematics, writing, and depth of processing;…

Schools throughout Australia both teach about computers and use computers as a medium for teaching at all levels of the educational system, but teachers use the computer to support existing pedagogic practice rather than looking to the computer as an agent of curriculum change. Drawing in a descriptive way upon a number of recent studies and…

The purpose of this study was to better understand teachers' perceptions of collaborative learning and to explicate how they use computer activities to promote cooperative learning experiences. Based on questionnaire responses and group meetings, the Office of Research, Evaluation, and Assessment (OREA) identified seven New York City teachers of…

Arguing that females need instruction in visuo-spatial skills before adolescence, when they begin to lag behind males in the development of these skills that are so strongly correlated with success in technical careers, this paper discusses the use of the three-dimensional and spherical graphics of ExperLOGO to develop spatial skills in students…

Part of the Communications Design Center's (CDC) on-going research on communication and document design, this report emphasizes the importance of a multi-level computer help system that goes beyond simple command descriptions to include assistance with goals and strategies within the application domain--in this case, automated authoring. The help…

The first of five sections in this report places intelligent computer-assisted instruction (ICAI) in its historical context through discussions of traditional computer-assisted instruction (CAI) linear and branching programs; TICCIT and PLATO IV, two CAI demonstration projects funded by the National Science Foundation; generative programs, the…
