Provides a short BASIC program, RANVAR, which generates random variates for various theoretical probability distributions. The seven variates include: uniform, exponential, normal, binomial, Poisson, Pascal, and triangular. (MVL)

Describes an interface that uses semiconductor metal oxides to detect low gas concentrations. Notes the detector has long life, high stability, good reproducibility, low cost, and is able to convert the gas concentration to an electrical signal with a simple circuit. Theory, schematic, and applications are provided. (MVL)

This paper describes a computer simulation of Buffon's needle problem. The problem considers the probability that a needle will cross a line when the needle is thrown in a random way onto the parallel lines a certain distance apart. The paper provides the algorithm and computer program. (YP)

Reviews empirical studies on the effects of computer use in education, covering research published up to mid-1988. Focuses on the issues of computer use effects at various grade levels, suitable types of programs, differences in usage in different programs, changes in students' attitudes, social effects, effects on low achievers, and future…

Presents the results of a survey of Purdue University students' knowledge of, use of, and attitudes toward computers as they enter the technical writing class. Contrasts the technical students with upper division humanities students and draws conclusions about documentation requirements and appropriate computer use goals for the students surveyed.…

Two incidents involving novice teachers with classes in grades 7 and 10 are presented. Then considered are the nature of intuitive mathematics and contributions computers can make to such intuitive mathematics, particularly in Algebra. (MNS)

Discussed are several designs for integrating computers into the instructional program of the school. Included are the classroom based computer, the laboratory model, and the mini-lab model. Floor plans and suggestions are included. (CW)

Information technology will be an important influence in education in the future. This article discusses the use of instructional technology for science teaching and considers the impact of technology on what is taught and how science is taught. (Author/CW)

Presents a study that investigates the knowledge and skills that relate to computer programing. Finds that knowledge and procedural skills are related to computer programing. Recommends that since instruction in computer programing facilitates problem-solving, computer programing courses should be augmented to include teaching template and…

Investigated were the effects of interactive computer-generated homework on unit tests, a final examination, and a comprehensive test given near the end of a Physical Science I course. The results indicated that the use of the homework reduced the effectiveness of the American College Test scores as a predictor of course achievement. (YP)

Summarized are six journal articles from five journals published in 1988. Included is one article which summarizes other studies. Sources of other similar articles are listed and discussed. Topics noted here include BASIC programing, computer-based instruction, student preparation, text density, and teacher workload. (CW)

Reports on a comparison of computer instruction at Japanese and American universities and colleges. Discusses hardware, education of students, computer graphics, and cooperative efforts. States that computer hardware in Japan is of high quality, abundant, and inexpensively accessed, and in America there is a stronger, direct instructional…

Examines the interaction between mode of computer assisted instruction and cognitive style on the understanding of concept relationships and mastery of factual information. Finds learners are more effective when matched to the appropriate mode of computer assisted instruction. (MVL)

Reports on acquiring and analyzing enzyme kinetics data using Apple microcomputers. Describes the experimental background and procedures, instrumentation, cautions, and construction aids. Cites applications which illustrate the use of a computer in a laboratory exercise. (RT)

Reports a protocol study of a freshman composition student to examine how significant a problem it actually is to learn to operate a computer, how influential students' expectations about computers are, whether the use of a computer promoted the importance of invention strategies, and whether computers encourage revision.
