Presented is the change-point estimation which is a variation on point estimation for a two-sample problem. This variation relies on the elementary properties of the expected value and variance operators, is intuitive and is easily accessible for introductory statistics courses. Data for this exercise may be produced by a BASIC program which is…

This note describes an inexpensive means for making high resolution analog voltage measurements using the parallel printer port of a standard IBM PC or compatible. (PR)

Addresses some basic aspects of Archimedes' law. Focus is on potential energy relationships so as to elucidate some common misunderstandings and to facilitate making bridges with other physical topics. A spreadsheet model is used as a simulation tool. (Author/NB)

As the largest university in the state, Virginia Polytechnic Institute and State University has developed a reputation as a computer-intensive, technology-rich environment. A case study examines the growth of this environment, the evolving relationship between technology and teaching and learning, and how assessment has recently assumed an…

This article discusses how laptop computers can be used in gifted education to create learner-centered environments, promote independent inquiry, stimulate creativity, risk taking, and development of passions, encourage complexity of ideas and higher level thinking, offer a variety of grouping options, and provide for flexibility and mobility.…

This article describes how the East Tennessee Technology Access Center is coordinating the use of new computer math programs designed for elementary children with and without disabilities. The use of the computer software to develop math skills, improve literacy, and increase the independence of students with disabilities is discussed. (Contains…

Presents a theoretical and empirical analysis of social interactions in computer-based learning environments. Explores technology use to support reciprocal understanding between teachers and students based on three technology-based learning environments in Finland and the United States, and discusses situated learning, cognitive apprenticeships,…

Discussion of the use of wide area computer networks to facilitate community-building and educational reform in elementary-secondary education focuses on a project in Pittsburgh called Common Knowledge: Pittsburgh that is seeking to develop new environments for teaching and learning. Guidelines for other school districts are presented. (LRW)

Discusses findings of the U.S. Congress' Web-Based Education Commission that examined how the Internet is being used to enhance learning opportunities for students. Addresses each of the seven areas in which the Commission suggested there is a strong need for action: broadband access; professional development; research and development; quality of…

Five preschool students with disabilities received direct instruction on matching shapes, colors, and numbers or letters, followed by guided practice using constant time delay under two conditions: computer-assisted instruction (CAI) with interactive software and teacher-assisted instruction (TAI). CAI was either equal or superior to TAI across…

A survey of faculty (n=60) and students (n=1,682) at Northwest Missouri State University concerning student expectations about information technology (IT) use in the classroom found that students expect IT use in all subject areas but desire it for between 40-50 percent of classroom activities. Students reported that PowerPoint and the document…

What uses of computers have effects on student engagement that seem most predicative of important learning? This research provides some evidence about this, examining empirical associations between kinds of software students use, teachers' pedagogical motivations behind their use, and one measure of student engagement: teachers' estimates of the…

Describes the United Kingdom Open University's FirstClass(TM) Computer conferencing system and its role in student support, taking as an example the way it is used for course choice. Suggests that while there are students who use it freely and apparently derive benefit from it, there are also substantial issues to be addressed about its relative…

Outlines fruitful areas of information and instructional technology (IIT) in education research: pedagogy of online environments; simulation, visualization, and modeling; mind-tools or cognitive tools; assessment tools; wireless computing; tools for learning communities; tools for project work and authentic tasks; integration of media, tools, and…

Researchers spent four months observing and interviewing students in French and Spanish language classrooms. Several themes emerged from the data which characterize the phenomenon of learner interaction in technology-enhanced language learning environments. This article presents a more contextualized picture of the implementation of technology in…
