This document provides administrative, management, supervisory guidance, and other information necessary to successfully conduct and support science symposia for grades 7-12. This text was originally developed by the Pacific Region Junior Science and Humanities Symposium program for participating schools and school districts in the Department of…

This study explores how an Inquiry-Based Demonstration Classroom (IBDC) professional development program affects the extended inquiry instruction of secondary science teachers and how teachers view their extended inquiry practice while involved in the IBDC professional development program. To assess the impact of the program on participants'…

This study incorporated classroom observations and taped interviews designed to reveal what each teacher believed about such matters as the nature of science and knowledge, the nature and purpose of education in general and science education in particular, and basic beliefs regarding God and purpose in life. Classroom practices of the…

The purpose of this study was to determine what representations of content existed in a secondary environmental science class and what happended to those representations during curriculum occasions. Initial data construction involved attention to what was actually going on during class sessions. Following this, a reanalysis of the data corpus with…

The concept of the mole and its relationship to chemical algebra is difficult for many high school chemistry students to master. This paper describes a study of the use of proportional reasoning when teaching mole relationships and its effect on developing critical thinking skills. The Test of Logical Thinking (TOLT) was used as a pre- and…

The mission of the National Center for Improving Science Education, a partnership between the NETWORK, Inc., and the Biological Sciences Curriculum Study (BSCS), is to promote changes in science curricula, science teaching, and assessment of student learning in science. The center analyzes and makes recommendations for policy and practice at the…

The Spacesuit wall chart to which this guidebook is a supplement, portrays Astronaut Bruce McCandless on his historic first untethered spacewalk using the Manned Maneuvering Unit during Shuttle mission 41-B (February 3-11, 1984), when he ventured 100 meters from the Shuttle's cargo bay and returned safely. The guidebook provides an in-depth…

From a science perspective, inquiry-oriented instruction engages students in the investigative nature of science. Inquiry involves activity and skills, but the focus is on the active search for knowledge or understanding to satisfy a curiosity. This digest further describes the distinguishing features of inquiry-oriented science instruction and…

Reports about U.S. schools have indicated the need for improvement of science teaching and learning. One of the solutions advocated calls for classroom contexts that allow for authentic practice under the guidance of teachers who model pertinent skills as practitioners in the field of study. The metaphor used to describe such teaching-learning…

The purpose of this guide is to educate young people about the problems associated with solid waste. The activities encourage them to think about options for reducing the amount of waste they generate and how they can help by recycling and learning about other waste management alternatives. The lesson plans deal specifically with garbage and…

The Second IEA Science Study (SISS) was carried out in 1983 in 24 countries. In the United States a second phase of testing was undertaken in 1986. This document describes the organization of the study in the United States and highlights some of the results and their possible implications for science education. The countries included in the SISS…

Each year, beginning in the early spring, Department of Defense Dependent Schools, Pacific Region conducts a Junior Science and Humanities Symposium program. The information for putting together such a program is contained in this document. Students are invited to conduct original research in the sciences, mathematics, the humanities, and computer…

Part of the Concepts in Science Project at the University of Surrey is to explore the complex structure and organization of ideas and meaning that children bring with them to their science lessons. To examine these ideas and meanings, a distinction is made between children's intuitive understanding of their world (children's science) and the…

This module is an activity/discussion-centered unit focusing on the importance of shoreline surface area. The module is part of a series designed to be used by teachers, students, and community members to help them utilize community resources in developing and teaching environmental concepts and responsibility, and in seeking ways to solve…

The primary task in solving a physics problem is to select ways of viewing the problem in terms of physical systems whose behavior is described by physical laws. The physical systems are, in general, only approximate models of the real-world systems. As models of real-world systems are made more accurate, the equations involved quickly become…
