Aims to acquire better understanding of how informal learning experiences may interface with classroom science instruction by investigating one aspect of science learning, that of scientific reasoning ability. Investigates possible differences in students' scientific reasoning abilities relative to their informal learning environments, classroom…

Introduces a grassroots environmental club in which members trained intensively in chemistry and biology for field testing. Discusses projects on endangered pitcher plants and biodiversity. (YDS)

Describes an experiment in which students use candy and containers of water to spark their interest in investigating. Students work in groups and make observations about what happens to the candy as it is placed in water. Features an experiment template for students to record their findings. (SAH)

Compares two first-grade teachers' hands-on approaches to teach measurement concepts. One, a constructivist, allowed students to figure out the dimensions of a Mayflower ship outline; the other immediately showed kids how to use a yardstick to estimate a whale's dimensions. Although initially more confused, the first class got more out of their…

Argues that inquiry is not merely using a "new" set of instructional practices, but rather involves a theoretical shift in viewing curriculum, students, learning, and teaching. (SR)

Presents an alternative approach to bonding and geometry--the electron domain model--which avoids some of the problems with the conventional approach. Discusses difficulties with the orbital model at the introductory level, electron spin and the Pauli exclusion principle, electron pair domains, nonequivalent domains, multiple bonds, and origins…

Shows how ionization energies provide a convenient method for obtaining electronegativity values that is simpler than the conventional methods. Demonstrates how approximate atomic charges can be calculated for polar molecules and how this method of determining electronegativities may lead to deeper insights than are typically possible for the…

This article discusses using questioning techniques for encouraging purposeful inquiry among gifted students in elementary grades through college levels. A variety of questioning strategies is recommended, focusing primarily on the higher end of Bloom's taxonomy to engage students in higher level thinking. A classroom example is provided.…

Explains the role and importance of standards in inquiry-based science teaching and preservice teachers' understanding of Science Teaching Standard A. Focuses on History Content Standard G of the National Science Education Standards (NSES). (YDS)

Introduces an inquiry-based unit in which students investigate characteristic environmental changes during outdoor activities. Integrates technology with data analysis, virtual field trips, and multimedia projects. Focuses on Content Standard A of the National Science Education Standards (NSES). (YDS)

Presents three science activities targeted to help urban students learn about nature: (1) observing coloration patterns of pigeons; (2) measuring local rainfall and comparing it to other areas; and (3) conducting a biodiversity study by observing a patch of lawn. (YDS)

To embed ongoing learning opportunities in routine school practices, superintendents must help schools create the collaborative cultures that enable teachers to work together, engage in collective inquiry, and learn from each others' experience. Suggestions for fostering quality staff development, clarifying priorities, and improving capacity are…

Explains how student projects enable second-year chemistry students to gain their first experience studying a chemistry-based problem before undertaking a major project during the third year of their chemistry studies. (DDR)

Discusses five realms to explore when distinguishing the efficacy of images. Explores six ethical issues that the use of images raise, such as misconception and sensationalism. Proposes a strategy for analyzing controversial images and illustrates the use of this methodology by analyzing the use of "Joe Camel" in advertising. (CMK)

Describes and evaluates an elementary science methods course in which the nature of science and scientific inquiry are embedded and explicitly taught. As a result of the course, incoming conceptions of science as primarily a body of knowledge changed to a more appropriate, blended view of science as a body of knowledge generated through the active…
