The ability and to make good estimates is essential, as is the ability to assess the reasonableness of estimates. These abilities are becoming increasingly important as digital technologies transform the ways in which people work. To estimate is to provide an approximation to a problem that is mathematical in nature, and the ability to estimate is…

A study is reported in which 7 children (2 girls and 5 boys, 11 to 12 years of age) with a year of LOGO Programming experience were asked to think aloud about how a LOGO procedure would work, and then to predict by hand-simulation of the programs, what the graphics turtle "pen" would draw when the program was executed. While all children…

Examines effects of deductive versus inductive learning strategies on performance, comprehension monitoring, and response confidence, using combinations of computer-based tutorials and simulations of Newton's laws of motion. Participants were 353 fifth graders. Deductive learning was defined as the tutorial combined with the structured or…

This study focuses on the effectiveness of "Solutions Unlimited," a computer software program developed to teach problem solving to middle level students. Fifty-one fourth, fifth, and sixth graders (21 girls and 30 boys) attending a private school in a small mid-west community were the subjects for this experiment; none had received…

Describes a geometry database unit for elementary classrooms in which students determine geometric attributes of a variety of shapes, and then set up a database that can be used to answer questions about the figures. Activities described include creating a database record format, simulating searches, and applying search criteria strategies. (five…

Creating a stock market simulation for the classroom computer reinforces math skills and can help students gain a good sense of how current events affect the economy, how to manage money and understand profit and loss, and how to use spreadsheet software. (IAH)

The article presents technology projects that provide real-life reasons for students to learn geography. A variety of online networks take students on online field trips, linking them with scientists, zoologists, archaeologists, and explorers. Other interactive software is available to simulate trips to various locations around the world. (SM)

Mathematics problem solving skills need to be developed through meaningful interactions. Computer simulations combined with cooperative learning methods provide students a context within which to construct an understanding of mathematics problem solving. This study examines the distribution and sequence of events that result in acquisition of…

Compares retention of popular science material by fifth grade students using either computer simulation software or expository text as the instructional tool. Finds a statistically significant superiority in favor of the expository text group. (RS)

This study involved students using simulation software in all phases of the learning cycle. Research on the use of simulations in science education has shown that the simulations can be used effectively in preinstructional and exploratory activities. Preinstructional and exploratory activities elicit and challenge students' alternative…

Describes a computer simulation game and database package, "Palestine in the First Century," developed for upper primary and secondary school religious education in Scotland and designed for use on a microcomputer with a printer. The effect of this type of software on the role of teachers and students is considered. (Author/LRW)

Reports on a pilot study that examined use by sixth-grade students in Costa Rica of a mathematical microworld written in LOGO. The investigation had three phases: (1) open exploration of the microworld; (2) group discussion and sharing of hypotheses; and (3) guided discovery and problem solving. (Contains 11 references.) (SLW)

A systematic study was conducted with a group of 10- to 12-year-olds using computer assisted instruction in a unit on fire which included a computer simulation of combustion. Three research questions were addressed to learn more about how the computer experience challenged the students' preconceptions: what the students thought the computer knew,…

This collection of case studies of classroom experiences in middle and secondary schools throughout the European Community describes the use of computers in mathematics education. The 16 studies are organized in four main groups: (1) experience in geometry using educational software and Logo in grades 5-10; (2) arithmetic number concepts,…

Discusses the integration of technology into the curriculum and how to design an interactive technological learning environment based on the concept of scientific sense-making. Highlights include the importance of sense-making in science education and an experiment on curriculum design for a fifth- to sixth-grade unit on seasonal change. (Contains…
