Hybrid computation facilities have been in operation at Louisiana State University since the spring of 1969. In part, they consist of an Electronics Associates, Inc. (EAI) Model 680 analog computer, an EAI Model 693 interface, and a Xerox Data Systems (XDS) Sigma 5 digital computer. The hybrid laboratory is used in a course on hybrid computation…

This report outlines the revised form of a program developed at the Research Institute of Logopedics and Phoniatrics (University of Tokoyo) for testing students' pronunciation and comprehension abilities, and discusses some refinements which have been made in the general approach. (See AL 002 685 for a description of the basic program.) Under this…

A potpourri of talks and discussion at a symposium on instructional strategies for computer-assisted (CAI) instruction are summarized in this report under these topic headings: Conference objectives; Are instructional strategies critical to CAI; The classification of instructional strategies; What is a strategy; Operational definitions of…

Progress is reported on four research tasks. An experiment tested the effectiveness of a computer-based phonology instructional system for second-language learning. In research on models of human-computer interactions, experiments were performed demonstrating that the provision of certain incentives to the users of a time-sharing system can have…

Psychologists and educational researchers who may be interested in installing a computer system in a behavioral science laboratory may learn from the experience gained in the development and operation of the Computer Facility at the Learning and Research Development Center of the University of Pittsburgh. Built around a PDP-7 computer, using a…

This 9-item questionnaire surveyed past, present, and projected media use in the Illinois junior colleges. Data were provided by the audio-visual or learning resources director of each responding institution. Some of the more important findings follow. In the past, opaque projectors (58 per cent), silent filmstrip projectors (46 per cent),…

A research program was planned to develop a first, experimental computer-assisted instruction system that would permit interaction with students in a subset natural English. At the base of this system was a model of cognition that would represent the knowledge content of the material to be taught and the student's current knowledge of it. A…

In decision-theoretic psychometrics, to determine the worth of individualizing instruction, equations are developed for expressing the cost and gain for applying an instructional sequence. This report is divided into three parts: first, a logical analysis of guessing; second, the effect of guessing on the quality of personnel and counselling…

Much work in computational linguistics, e.g. the preparation of concordances and text files, has dealt strictly with the surface of language, treating it as nothing more than strings of characters or phonemes. The "classical" scheme, developed as a result of dissatisfaction with the inability of such surface systems to deal with problems such as…

Evergreen State College is an unprecedented flexible, sophisticated educational instrument designed to avoid depersonalization. Students are treated as responsible adults and are expected to work closely, as colleagues, with their teachers. Curriculum planning reflects the belief that graduates would change their career pattern and life styles at…

The Air Force has been plagued with the rising cost of technical training and has increasingly turned to computer-assisted instruction (CAI) for better cost effectiveness. Toward this aim a trial of PLATO IV, a CAI system utilizing a graphic display and centered at the University of Illinois, was initiated at the Chanute and Sheppard training…

INSCAL multidimensional scaling, an objective methodology for formulating effective technical information sequences for computer-assisted instruction, was shown to be of value with respect to defining the information complexity of technical material, developing sequences of key concepts within technical material, and providing an index of expert…

From some simple and schematic assumptions about information processing, a stochastic differential equation is derived for the motion of a student through a computer-assisted elementary mathematics curriculum. The mathematics strands curriculum of the Institute for Mathematical Studies in the Social Sciences is used to test: (1) the theory and (2)…

Computers can effectively promote learning, but only if they are used in ways which are consistent with the natural processes of learning. The analysis of several computer-assisted instructional (CAI) projects reveals that computer-related learning environments are most successful when they closely resemble the natural learning environment found…

Activities conducted during the period January 1966-June 1966 as part of the Pennsylvania State University computer-assisted instruction (CAI) project are reported. The objectives of the project are described in a previous document (IR 000 511). This report first provides information on the physical facilities and equipment used in this stage of…
