Two studies were conducted to determine the effects of gender, reasoning level, and inductive and deductive computer-simulated experiments (CSE) on problem-solving abilities in introductory general chemistry. In the pilot study, 254 subjects were randomly assigned to control (computer-assisted-instruction tutorials), inductive or deductive CSE…

Articles and activities written for the senior secondary level explore the complex links between militarization and underdevelopment. The articles discuss choices between missiles and food in developing countries, the internal and external causes of militarism, and the hidden costs of militarism. Case studies of the Kwajalein Atoll and Ethiopia…

This report characterizes human problem solving in digital circuit design. Protocols of 11 different designers with varying degrees of training were analyzed by identifying the designers' problem solving strategies and discussing activity patterns that differentiate the designers. These methods are proposed as a tentative basis for assessing…

DIMTEST is a statistical test procedure for assessing essential unidimensionality of binary test item responses. The test statistic T used for testing the null hypothesis of essential unidimensionality is a nonparametric statistic. That is, there is no particular parametric distribution assumed for the underlying ability distribution or for the…

Problems in the measurement of gain in adult literacy programs were investigated through repeated testing of a group of students in adult basic education and General Educational Development classes and through computer simulations. Ninety-two students were tested at 3 different times over 7 months with a battery of norm-referenced reading and…

This paper contains the results of a study on the importance of discovery learning using computer simulations. The purpose of the study was to identify what constitutes discovery learning and to assess the effects of instructional support measures. College students were observed working with an assignment and a computer simulation in the domain of…

The field of instructional technology is characterized by its products, such as instructional media, and its processes, such as instructional design. The process of instructional technology has been shaped by advances in learning and instructional theory over the past 50 years. Much of the development work of the field to date has been on direct…

Whether item response theory (IRT) is useful to the small-scale testing practitioner is examined. The stability of IRT item parameters is evaluated with respect to the classical item parameters (i.e., p-values, biserials) obtained from the same data set. Previous research investigating the effect of sample size on IRT parameter estimation has…

The graded response model for two-stage testing was applied to an attitudes toward science scale using real-data simulation. The 48-item scale was administered to 920 students at a grade-8 equivalent in Singapore. A two-stage 16-item computerized adaptive test was developed. In two-stage testing an initial, or routing, test is followed by a…

As drill and practice programs in computer assisted instruction (CAI) in English give students a chance to test their understanding and free the teacher from test grading, they seem a legitimate if unexciting use of the computer; but what seems less defensible is that, according to some estimates, 90% of available CAI software is of this drill and…

Advantages of using the microcomputer as an interactive electronic blackboard are discussed, and programs and programming techniques are described to illustrate the construction, design, storage, and modification of colorful and animated graphic displays. The methods described are based on use of an Atari 800 microcomputer but could be used on…

This supplement updates the first supplement to the original catalog of available PLATO systems instructional materials. The original catalog was published in April 1980 and the first supplement in November 1981. The lessons described in the current publication have been used in actual instructional situations or have had adequate testing to…

A 2-phase project in which fifth grade students create their own country is described. The project offers a strategy for teaching a comprehensive, interdisciplinary unit on economics. In the first phase, students and teacher create an imaginary country. Separate sections outline the teaching procedure involved in this phase: locating the country;…

One of a series of units introducing secondary school students to business issues, this packet focuses on the television industry and its social and political influence. A teacher's guide and student materials are provided in two separate sections. Following an overview of objectives and activities, the teacher's guide outlines five daily lessons.…
