This memorandum contains engineering information relevant to the use of communication satellites for educational purposes. Information is provided for ground terminals as well as satellites. Satellite related issues addressed include: (1) expected life of service of various satellites, (2) constraints on the availability of the satellites, (3)…

This paper presents a study on the effects of various data compression methods from the viewpoint of central computer to terminal communications on a large graphics oriented timesharing system, PLATO IV. The desired goal is to increase terminal display speed without significant increase in the transmission error rates. While the major emphasis in…

This report presents a cost-effectiveness model for preservice and inservice teacher training in Australia, using a microteaching technique, relating educational (student-centered) factors and cost (management-centered) factors. The report is divided into four parts: (a) a literature survey and the experimental study; (b) attachments to Part A;…

This report is one of eight volumes in the National Institute of Education's Compensatory Education Study which describe the findings and procedures of the Instructional Dimensions Study, an indepth assessment of the relationships between selected instructional constructs and students' achievement. Program cost analysis was included in the study…

Cost estimates for Computer Assisted Instruction (CAI) depend crucially upon the particular assumptions made about the components of the system to be included in the costs, the expected lifetime of the system and courseware, and the anticipated student utilization of the system/courseware. The cost estimates of three currently operational systems…

Location theory was extended into the domain of information-processing firms by attempting to optimally place a federal research and development agency according to its information-processing functions. The techniques used consisted of identifying possible locations within the continental United States, examining the costs of performing the…

The investigation assessed participant perceptions of the costs and benefits of earning a GED high school equivalency certificate. Regression analyses revealed that current income is a better predictor of future earnings than age, anticipated schooling, and anticipated occupation and salary increases for 1968 to 1971, collectively.

A Davenport, Iowa, school district has remodeled a department store into a vocational and technical school currently housing 250 students on half-day programs. (Author/MLF)

A cost analysis shows an all-electric Illinois middle school actually operating at less than the original estimate. (Author)

The technique of intermittent control systems for air quality control as developed and used by the Tennessee Valley Authority is investigated. Although controversial, all Tennessee Valley Authority sulfur dioxide elimination programs are scheduled to be operational this year. Existing or anticipated intermittent control systems are identified. (BT)

Presents a brief summary of a detailed multidisciplinary research study of the services provided to handicapped children by the Rand Corporation and suggests that through coordination of efforts in prevention, identification, direction, medical treatment and vocational training we could achieve greater benefits, with long-range cost-effectiveness.…

Municipalities and industry are being forced to seek alternatives to sanitary landfills and incineration as means of eliminating solid wastes. Based on the Columbia study, the two most cost-effective, environmentally acceptable alternatives are the high temperature, oxygen-fed pyrolysis process and the co-combustion of refuse-derived fuel in…

The article defines the major elements (fundamental questions, basic assumptions, anticipated costs, projected savings, and return on investment) of a cost model, discusses the function and importance of each of these elements, and illustrates the development and construction of a cost model through an analysis of a hypothetical speed reading…
