This research examined the significance of facet selection in a multi-facet Rasch model analysis. The residuals or remaining error in a multi-facet Rasch model were further studied in the context of a full and reduced data-to-model fit chi-square, given the specific design. In addition, main effect facet contributions to person measures and the…

Part of the Understanding Our Environment project that is designed to engage students in investigating specific environmental problems through concrete activities and direct experience, this unit places Earth in the context of its environment-the Universe-then focuses on Earth as seen from satellites. Students analyze patterns formed by the…

This book contains 25 experiments designed to help students understand some of the science used every day. Each experiment includes a list of materials, a series of easy-to-follow steps, an explanation of the scientific principle demonstrated, and additional scientific facts and information. No special or expensive materials are required.…

In 1991, a survey questionnaire concerning undergraduate education in geology was sent to a nationally representative sample of 597 four-year colleges and universities. Of these, 275 had an undergraduate geology department or a department with a geology program, and met the criteria for inclusion in the study. Responses were received from 262 of…

Where on Earth are you? Where is your home, your school, or the bookstore on the globe we call Earth? The activities in this book are designed to show children how to orient themselves on this planet. The book is divided into three main sections. Section 1, "Finding North, No Matter What," contains the following subsections: (1) Finding…

National concerns about the quality and effectiveness of science teaching have resulted in several efforts directed at restructuring the United States' science curriculum. This digest discusses recent initiatives of the Earth Systems Education. Topics discussed include: (1) efforts to understand the planet Earth; (2) the Program for Leadership in…

Technologies can play a role in restructuring schools, but they can also effectively support existing school structures depending on how they are designed and used. This paper contrasts the organizational impact of two technology systems in terms of the physical location in the school, the curriculum, how time is scheduled, and the opportunities…

Uses a vortex device as a model to study low-pressure systems and other related investigations. (LS)

Explains the arrangement of materials in a classroom to simulate land or weather conditions. On each desk in the room pertinent bits of information are placed. Students gather bits of information and synthesize material into an overall map of the area. (CP)

Considers cosmic rays and relationship to fields of geophysics and astrophysics. Reveals importance of solar eclipses in the study of cosmic radiation. (CP)

Suggests that current crust-evolution research can and should be used in courses K-12. The NAGT is going to develop suitable materials to provide teachers with the necessary concepts and understandings as well as materials for students in an effort to provide a more rapid response to and use of the constant progress and change occurring in…

Presents developments in the teaching of earth science in Venezuela, Brazil, Uruguay, Argentina, Bolivia, and Colombia. (GS)
