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)

Discussion of educational applications of new information technologies in Japan highlights the use of microcomputers. Surveys of elementary and secondary schools are reported; inservice teacher training is described; and government involvement in educational policy is discussed, focusing on two appended reports on microcomputers and software…

Investigates whether elementary school students can construct operations of thought for integers and integer addition crucial for understanding elementary algebra. Two sixth graders were taught using a computer. Results included both students being able to construct mental operations for negating arbitrary integers and determining sign and…

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)

Presents reviews of three software packages. These are "Ant Farm," a game of problem solving using guess and check or trial and error; "Learning Place Value"; and a set of three utility programs--"Mastering Math: Diagnostic System,""Mastering Math: Worksheet Generator," and "Mastering Math: Management System." (PK)

Defines cognitive computer tools as software programs that use the control capabilities of computers to amplify, extend, or enhance human cognition; suggests seven ways in which computers can aid learning; and describes the "Learning Tool," a software package for the Apple Macintosh microcomputer that is designed to aid learning of…

Discusses program designed by the Educational Computer Consortium of Ohio (ECCO) to address the problems of equity in computer technology among minority, female, economically disadvantaged, and handicapped students. Six projects focusing on elementary and secondary school girls, minorities and economically disadvantaged students are described, and…

Suggests that microcomputers permit even young children to investigate mathematical relationships and to solve problems. Activities, both on the computer and off the computer, are suggested. (PK)

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 results of a survey of British secondary school students which was conducted to obtain information about microcomputer use both in school and at home. Highlights include gender differences, students' attitudes toward computers, experience with computers, assessment of programming ability, and characteristics of competent programmers. (LRW)

This special theme issue is dedicated to topics related to courseware in higher education. Aspects addressed include faculty development of software; new technologies and their effects on knowledge; microcomputer-based software; courseware publishing; information sharing and software distribution; and future teaching and research projects. (LRW)

Compares knowledge and attitude levels of elementary, secondary science, and other secondary teachers on water resources. Evaluates an interactive computer simulation, the "Water Resource Management Simulator" (WRMS), as a training tool for inservice teachers. Users of WRMS exhibited higher knowledge scores than nonusers. No differences…

Groups of retarded and nonretarded children were investigated as they learned three rules underlying problems adapted from the Raven Progressive Matrices Test: rotation, imposition, and subtraction. Results were seen as consistent with theories that emphasize transfer flexibility as one potential source of individual and comparative differences in…

Describes the creation of a series of interactive video modules on dental hygiene at Luzerne County Community College. These modules are intended to supplement instruction in a community dentistry and health education course and to guide students in an assignment to develop and implement dental health projects in their community.
