Background: The goal of this research was to determine students' perceived self-efficacy in science classes through involving students in expanding disciplinary core idea (DCI) and interdisciplinary core idea (ICI) maps, as a method to visualize knowledge (utilizing mind mapping and concept mapping) to support students to integrate…

Rarely are scientific phenomena isolated to a single discipline such as biology, chemistry, physics, Earth science, or others. Rather, these phenomena span multiple disciplines and often require bringing together content and understandings from multiple disciplines to engage with or explain the target phenomena. This study uses a model-based…

A model estimating the contributions of sulfur compounds by natural and human activities, and the rate of removal of sulfur from the atmosphere, is based on a review of the existing literature. Areas requiring additional research are identified. (AL)

Describes construction of two inexpensive three-dimensional models (tetrahedrons) using glass tubing and colored plastic sheeting. Diagrams show how these models are used in explaining how a point is plotted in a four-component system and how the composition of a point is deduced from its position in the model. (CS)

Two programs are described for teaching earth science and introductory chemistry to secondary students with learning disabilities. Development of the two models involved curriculum revision to engage students in higher order thinking, teaching fewer topics in more depth, and design of materials to provide an integrated, problem-solving basis for…

Described is a report outline for geologic reports. Essential elements include title; abstract; introduction; stratigraphy; petrography; geochemistry; petrology; geophysics; structural geology; geologic history; modeling; economics; conclusions; and recommendations. (Author/CW)

SCIENCE EQUIPMENT, TEACHING AIDS, AND MODELS THAT HAVE BEEN OR ARE BEING DEVELOPED THROUGH THE NATIONAL SCIENCE FOUNDATION'S SCIENCE TEACHING EQUIPMENT DEVELOPMENT PROGRAM ARE DESCRIBED IN THIS BULLETIN. REPORTS FROM ALL PROJECTS SUPPORTED UP TO MARCH 15, 1963, ARE INCLUDED. ITEMS ARE CLASSIFIED ACCORDING TO DISCIPLINE AND APPROPRIATE…

The Virtual Museum of Minerals and Molecules (VMMM) is a web-based resource presenting interactive, 3-D, research-grade molecular models of more than 150 minerals and molecules of interest to chemical, earth, plant, and environmental sciences. User interactivity with the 3-D display allows models to be rotated, zoomed, and specific regions of…
