Teachers interested in fostering science learning through inquiry or projects must play a complex role in discourse with students. They must scaffold student activities in the classroom without taking away students' active roles. This paper provides a framework for a specific form of scaffolding open-ended science inquiry based on the notion of…

The purpose of this study was to investigate the effects of a problem solving based instructional model on earth science students' achievement and alternative frameworks. Students' opinions toward the instructional method were also investigated. The investigations employed a pretest/posttest control group design to detect any significant change.…

This study evaluates the effectiveness of a mnemonic approach to teaching about the solar system to non-leveled Grade 9 students versus a traditional outline format. A mixture of 54 regular and special education students participated in the control group receiving facts about the solar system through lecture and transparencies and recorded the…

The theme of the fifth annual World's Largest Math Event (WLME 5) is "The Power of Nature." This theme encourages students to explore natural forces that affect humankind, including phenomena such as hurricanes, earthquakes, and snowstorms, and the mathematics that underlies their study. The 15 activities for WLMES have been grouped into five…

This paper presents a literature review related to the time spent teaching science and a study designed to test the hypothesis that student achievement in science is related to classroom hours devoted to science instruction. The study involved testing two groups of eighth grade earth science students (N=200) over instructional material presented…

Describes the joint effort of Canada and NASA in monitoring the Canadian environment using remote-sensing techniques. The project involves the Earth Resources Technology Satellite and has been used to observe seasonal changes, extent of snow cover, crop growth, sea ice, and land use patterns. (GS)

Describes the use of remote sensing methods in Europe and explores the problem of interpretation of the raw data obtained. (GS)

Describes the services of the National Referral Service of the Library of Congress which assists people with questions in science and technology by referring them to organizations which can answer those questions. (BR)

An earthquake is a shaking of the ground resulting from a disturbance in the earth's interior. Seismology is the (1) study of earthquakes; (2) origin, propagation, and energy of seismic phenomena; (3) prediction of these phenomena; and (4) investigation of the structure of the earth. Earthquake engineering or engineering seismology includes the…

The Federal Republic of Germany's space policy is designed to promote basic research, contribute to the development of space technology, and apply the findings in the public and private sectors. It is also aimed at enhancing the competitiveness of the West German space industry and helping countries of the Third World to solve their development…

This continuum is designed to be used as a guide to aid science educators, elementary teachers, administrators, and others in developing elementary school science curricula. It is divided into five major competency areas: (1) processes of science; (2) biological science; (3) physical science; (4) earth and space science; and (5) attitudes (toward…
