Preschoolers 4 and 5 years of age were found to use four strategies differing in temporal characteristics as they solved simple addition problems with sums of 10 or less. Three strategies had visible and/or audible aspects, and one was covert, involving retrieval from memory. The harder the problem, the more often the children used an overt…

This monograph defines and describes research in the study of adoption of electronic text services in higher education institutions. Electronic text here includes text and graphic information encoded and transmitted via broadcast, signal, or cable, under user control. It places the diffusion of electronic text in higher education within the…

This paper reports on a computer simulation of cloze retrieval tasks. It first outlines the ideas that were assembled and translated into the model used to compose the simulation and describes the method used in developing the simulation. It then reports on a comparison of the time required by a computer and by human subjects in responding to…

This bibliography lists publications describing the scope, time span, depth, variety, and relevance of the satellite work done by the Institute for Telecommunication Sciences from 1958 through 1976. Works cited are listed by author with six categories: propagation, antennas, modulation or signal design, electromagnetic interference and frequency…

The simulation of a sampled-data system is described that uses a full parallel hybrid computer. The sampled data system simulated illustrates the proportional-integral-derivative (PID) discrete control of a continuous second-order process representing a stirred-tank. The stirred-tank is simulated using continuous analog components, while PID…

This paper concerning the development of simulation materials for training correctional counselors in family counseling is oriented toward developing sequential counseling materials which will have positive consequences for the trainees' use. An offender family counseling training module is presented utilizing a series of transparencies depicting…

A simple deterministic macroeconomic computer model was tested in a junior-senior level economic statistics course to demonstrate how and why some common errors arise when statistical estimation techniques are applied to economic relationships in empirical problematic situations. The computer model was treated as the true universe or real-world…

This three-part book, a collection of articles by some of the foremost researchers in language comprehension, examines the thought processes involved in listening to conversation or in reading a page of text. The first part of the book deals with what the reader stores from a page during and after comprehension; it investigates the reader's use of…

The mission of Project SWEP (Skyline Wide Educational Plan) was to conceptualize the secondary school of the years 1980-2000 and to develop a viable working model of such schooling. The staff first sought a comprehensive description of the society of the 1980s and beyond, with emphasis on how education might be impacted by various facets of that…

The major purpose of this evaluation report is to scrutinize the Skyline Wide Educational Plan (SWEP) research methods and analytical schemes and to communicate the project's constituency priorities relative to the educational programs and processes of the future. A Delphi technique was used as the primary mechanism for gathering and scrutinizing…

The purposes of this terminal evaluation report are to determine the extent to which the major goals of the Skyline Wide Educational Plan (SWEP) project were achieved, to evaluate the utility of the products of SWEP studies, and to communicate the results to appropriate audiences. Information relative to four major project components is presented;…

This paper describes and discusses three studies concerned with the representation of children's knowledge as revealed in the ways that children, ages 5 to 17, perform a scientific induction task. A variant of Piaget's balance scale prediction problem was chosen as the experimental task; a formal model for different levels of children's knowledge…

A simulation study of library-based information retrieval systems is described. Basic models for each of several important aspects are presented: (1) user behavior, emphasizing response to quality and delays in services; (2) the scheduling of services and the organization of the machine-readable files; and (3) the distribution of conventional…

Beginning January 1, 1969, Systems Research Group (SRG) undertook a project to develop operational cost simulation models of three of the colleges of applied arts and technology in Ontario. These models, and the data needed to feed them, have been developed and are now operating. SRG describes their progress to date and identifies the remaining…
