Describes how Logo has been used to introduce primary children to mathematical concepts often considered to be too difficult for them. Outlines how Logo has been used to introduce the estimation of distance, the estimation of angles, symmetry, rules of precedence, the concepts of random, and the use of variables. (TW)

Discusses a new computer modelling system and compares a teaching strategy that uses computers to explore exponential decay with a teaching method employing the Cellular Modelling System in which the monitoring of a real experiment and the development of a model representing the experiment are done at the same time. (CW)

Provides an introduction to new educational technology. Describes interactive video as a means to enhance learning not to improve teaching. Outlines some of the fears, apprehensions, and antipathies associated with this technology and suggests ways to alleviate them. (CW)

Describes a five year research project in plant ecology by successive teams of students. The aim was to identify environmental factors which were determining the distribution of the vegetation on a pitheap. Includes descriptions of vegetation, soil properties, and computer assisted analysis of results. (Author/CW)

Describes some developmental changes in children's free creations with pattern blocks and demonstrates how to build on this natural interest to teach Logo programing. (PK)

Discussed are field analyses of data involving paleocurrent directions using a goniometer and special programs for a pocket computer. States that on-site evaluation can provide immediate realization and verification of anomalous results. Includes computer programs and directions for building a goniometer. (CW)

Discusses the trends in education toward computer equipment and computer assisted learning in England. Surveys some of the attitudes of educators and students toward home-based, computer-aided learning, hardware and software. Anticipates future developments in technology for education. (CW)

Discusses the snowflake curve as a way to introduce the topic of sequences and series. Computer programs which produce graphic results are included. (PK)

Discusses the use of a computer program designed to solve the mathematical model associated with soil nutrient uptake by plant roots and to predict the nutrient uptake. Describes a user-friendly personal computer version of this program. (TW)

Describes survey of public school administrators in Allegheny County, Pennsylvania, which was conducted to determine how their perceptions of computer training needs vary across administrative categories. The needs assessment questionnaire is described, ranking of computer competencies is discussed, and implications for educational planners for…

Describes direct and indirect voltage input techniques and their applications to voltage measurements with a microcomputer. Details circuitry that can be used for this with a gameport. Gives examples of circuit modifications, application of voltage measurement, and alternatives to this method. (CW)

Discusses the mathematical properties of magic squares. Includes a computer program that will test magic square criteria. (PK)

Describes methods and software for graphing representation of a complex function of a complex variable. Includes an application of a graphical interpretation of the complex zeros of the cubic and their properties. (PK)

Presents the results of statistical analyses and interpretations of data obtained from students in two engineering fundamentals courses on an attitudinal survey. Indicates positive and significant improvement in student attitudes toward their own drawing abilities and the importance of drawing in their lives and careers. (CW)

Describes five computer software packages; four for MS-DOS Systems and one for Apple II. Included are SPEC20, an interactive simulation of a Bausch and Lomb Spectronic-20; a database for laboratory chemicals and programs for visualizing Boltzmann-like distributions, orbital plot for the hydrogen atom and molecular orbital theory.
