Difficulties in implementing effective instruction for at-risk students arise from two challenges: the transfer of evidence-based knowledge and the lack of economic resources. Computer-assisted programmes offer a suitable solution, providing quality instruction using low-cost resources. Thirty-two first-grade students with early learning…

In an ongoing study, RAND researchers are evaluating the effectiveness of Carnegie Learning's Cognitive Tutor Algebra I (CTAI) curriculum, a technology-based curriculum that combines classroom instruction with individualized instruction by a computer-based tutor. While the effectiveness of the curriculum in raising student achievement is the main…

This paper reviews current research on the effectiveness of interventions and reforms that seek to improve the math preparedness and success of high school students entering college. Based on gaps in the research knowledge, it also provides recommendations for further inquiry in particular areas. The studies reviewed here are selected from…

Virtual learning is not for every student, but it's not science fiction, either. Right now in Michigan, it's being used by thousands of students in hundreds of virtual courses in urban, rural and suburban school districts. In fact, Michigan has been seen as a national leader in virtual learning. This study analyzes the financial costs and academic…

Electrical stimulation of nerve and muscle tissues is frequently used for teaching core concepts in physiology. It is usually expensive to provide every student group in the laboratory with an individual stimulator. This article presents the design and application of a low-cost [about $100 (U.S.)] isolated stimulator that can be controlled by two…

There is intense interest in computer games. A total of 65 percent of all American households play computer games, and sales of such games increased 22.9 percent last year. The average amount of game playing time was found to be 13.2 hours per week. The popularity and market success of games is evident from both the increased earnings from games,…

This guide in the selection of instructional computer systems compares four systems representing different cost categories in terms of 25 parameters. Costs and benefits of each system are enumerated, and problems associated with cost benefit analysis are discussed. (Author/JEG)

Some studies of school technology demonstrate that cost-effective analysis allows similar programs to be compared. Cites a report "Power On! New Tools for Teaching and Learning," available from the Government Printing Office. (MLF)

The purpose of this article is to discuss hardware issues and help educators assess their hardware needs in order to determine the best computer hardware for their school program. Good and bad features, flexibility, reliability, cost effectiveness, and optimum classroom configuration are given particular attention. (LMO)

A potentially powerful instructional delivery system, "intelligent videodisc" may fit CAI to the institutional structure of education for the first time. However, it will probably face traditional barriers, including teacher unwillingness and tight budgets. (JEG)

Teachers appreciate online services with tailored education features--such as Classroom Prodigy, the Scholastic Network on American Online, and dedicated portions of Compuserve and Delphi Internet Services. Online services are speedier and more accessible than Internet, allow interstudent communications, and offer teachers a low-cost menu of…

Computers may someday replace teachers at essay grading. In recent research, a blind test has demonstrated that a computer can simulate the judgment of a group of human judges on a brand-new set of essays. Moreover, the PEG (Project Essay Grade) program can do a better (and more cost-effective) job than the usual two human readers while providing…

This discussion of the use of computer-assisted instruction in universities focuses on the quality of motion video used in hypermedia educational software. An evaluation experiment shows that end-users are not deterred by lower quality motion video that costs less. (LRW)

Operating on the premise that different approaches to computer-assisted instruction (CAI) may use different configurations of hardware and software, different curricula, and different organizational and personnel arrangements, this study explored the feasibility of collecting evaluations of CAI to evaluate the comparative cost-effectiveness of…

Examines teletraining as a cost-effective, high quality alternative in distance education. Teletraining methods include: audio-only, audio-graphic, computer-conferencing, one-way video broadcast, one- or two-way video with audio interaction, and desktop videoconferencing. (AEF)
