Investigated the effects of units using computers and computer-administered tests. The greatest benefit was attained by those using the units and attending lectures. Students using both the units and tests did not perform as well as the lecture only group. Explores the correlation between high school grades and the methods. (Author/YP)

Described is an exercise which examines the effect of reading aloud a technical passage of science material while the heart is monitored by a computer. The experimental setup, design, and data analysis are discussed. (CW)

Discusses the sociohistorical approach to tools and change. Explores the possibilities of computer-supported cooperative work. Discusses formative experiments on the educational environment as research opportunities. Illustrates the organizational impact of school technology by describing a project intended to create an environment for…

Discusses the use of the mathematics classroom for discovering the relationship among computers, mathematics, and real-world problems. Provides three probability problems and compares the results of three methods, actual trial, computer simulation, and mathematical solution. (YP)

Discusses using the computer to promote versatile learning of higher order concepts in algebra and calculus. Generic organizers, generic difficulties, and differences between mathematical and cognitive approaches are considered. (YP)

Describes a five-dice game, horse. Discusses the offensive player's strategy using the ideas of probability, such as counting outcomes, mutually exclusive events, conditional probabilities, zero sum games, and the use of computer. (YP)

The impact and uses of new technologies in science teaching are discussed. Included are computers, software, sensors, integrated circuits, computer signal access, and computer interfaces. Uses and advantages of these new technologies are suggested. (CW)

Described is an approach that uses a computer spreadsheet program to calculate entropy change at constant temperature and pressure. The calculated values can be used in an associated graphing program. (CW)

Results of a study involving 300 high school and middle school students indicated that students whose homes were called with a computer dialing device when the child was absent from school had a better overall attendance record than students whose homes were not called. (IAH)

Describes several phenomena in which interesting properties of numbers are demonstrated. Includes discussions of amicable, perfect, and sociable numbers. Presents computer programs for conducting a number chain search. (RT)

Shows that graphs can reveal much about feedback systems that formula conceal, especially as microcomputers can provide complex graphs presented as animations and allow students to interact easily with them. Describes feedback systems, evolution of the system, and phase diagram. (YP)

Describes a process of mathematical investigation involving generalized Fibonacci sequences. Provides the derivation using expressions, BASIC programs, and numerical verification. (YP)

This annotated bibliography provides 302 references to materials in English and in French dealing with the introduction and development of computer technology in secondary education systems in various countries. Topics covered by the bibliography include national policies, teacher training, human resources development, informatics as a subject,…

Computer-assisted learning programs are assessed relative to the types of knowledge and ways of learning, the connection with actual experience, motivational factors, and responsiveness. Results indicate that computer-assisted programs impart cognitive skills as well as complex knowledge. Motivational factors are quite prevalent, however learning…

Describes a computer program presenting four genetics problems to monitor the problem solving process of college students. Identifies three main areas of difficulty: computational skills; determination of gametes; and application of previous learning to new situations. (Author/YP)
