Ninety-six 9th, 10th, and 11th grade students, randomly selected to include equal numbers from each grade level, from both sexes, and from each ability quartile were randomly assigned to either experimental or control procedures. The experimental group used the computer to select courses, while the control group was assisted by the counselor.…

The major advantages in computer-assisted instruction (CAI) are the potential for the individualization of instruction and the savings in instructional time. CAI's major disadvantages include the large amount of time required for course development, personnel required, initial outlay of funds, and the total cost. Other disadvantages, due to the…

Student motivation is a central issue in computer-aided instruction (CAI), since even the most sophisticated teaching programs will require directed and sustained effort at the learning task. Technical students, who have to master long and difficult courses, present special motivational problems. A review of the literature indicates that…

Three characteristics of computer-assisted instruction (CAI) make it suitable for individualizing instruction: adaptive response by the student, continual evaluation of the student's responses, and adaptability of instruction to the individual's responses and his achievement levels. CAI systems are being used for laboratory computing, record…

SCHOLAR is a computer-assisted instruction (CAI) system which is capable of true man-computer dialog. Using a subset of English, the system is capable of generating questions, answering questions, analyzing responses, and producing subsequent actions. SCHOLAR has a data base that is a complex but well defined information structure in the form of a…

Industrial education, because of expanding technology, must acknowledge the changing realities of the world in which it functions and for which it prepares individuals to participate. Therefore, the purpose of this study was to examine selected public schools, at the elementary, secondary, and higher educational levels, for the purpose of…

The PLATO IV computer-based instructional system consists of a large scale centrally located CDC 6400 computer and a large number of remote student terminals. This is a brief and general description of the proposed input/output hardware necessary to interface the student terminals with the computer's central processing unit (CPU) using available…

An audiovisual teaching machine (AVTM) presents programed audio and visual material simultaneously to a student and accepts his response. If his response is correct, the machine proceeds with the lesson; if it is incorrect, the machine so indicates and permits another choice (linear) or automatically presents supplementary material (branching).…

The Paris Faculty of Science is developing programs in computer-assisted instruction (CAI). Their first goal is to develop "questionnaires" (instructional sequences) administered by teletype machines which check on a student's knowledge in an area and draw his attention to basic concepts, definitions, and theorems in that area. Using an…

This booklet outlines guidelines for choosing a teaching technique and describes a wide variety of techniques. It is intended as an aid to teachers of all subject matters. The first chapter develops a number of principles for choosing a teaching technique appropriate to a given situation, and divides techniques into three categories: 1) real-life,…

This paper defines the structure of a semantic network for use in representing discourse and lexical meanings. The structure is designed to represent underlying semantic meanings that, with a lexicon and a grammar, can generate natural-language sentences in a linguistically justifiable manner. The semantics of natural English can be defined as a…

Computer programs which teach concepts and processes related to biology, earth science, and chemistry are presented. The seven biology problems deal with aspects of genetics, evolution and natural selection, gametogenesis, enzymes, photosynthesis, and the transport of material across a membrane. Four earth science problems concern climates, the…

The design, development, and evaluation of a computer-assisted instruction (CAI) program in first-year college chemistry is described in this report. The program was centered around the concept of chemical equilibrium and used a systems approach with explicitly stated guidelines. The purpose of this experiment was not to measure the effectiveness…

The requirements for a theory of instruction can be described in the following list of criteria: 1) a model of the learning process; 2) specification of admissible instructional actions; 3) specification of instructional objectives; 4) a measurement scale that permits costs to be assigned to each of the instructional actions and payoffs to the…

The guidelines and procedures for the development of course materials for presentation by a computerized instructional system are described in this report. The tutorial mode of the instructional model is emphasized. The guide is intended to furnish the experienced instructional programer with a ready reference which can be used to facilitate the…
