The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…

This book provides a complete Scope Sequence and Coordination teaching module. First, craters are introduced as a generally observable phenomena. Then, by making craters and by investigating the results, students gain close-up, hands-on experience with impact events and their products. Real crater examples from the Moon and elsewhere are included…

This book offers a large collection of Earth science projects and project ideas for students, teachers, and parents. The projects described are complete but can also be used as spring boards to create expanded projects. Overviews, organizational direction, suggested hypotheses, materials, procedures, and controls are provided. The projects…

This book suggests an approach to science instruction that integrates literature as an alternative form of instruction or to enrich textbook instruction. It uses conceptually and factually correct works of fiction and outlines activities where students are allowed to do the majority of the work and the teachers act as facilitators. Though the…

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…
