This document presents activities in the physical sciences. Activities are grouped in the following chapters: (1) "Science and Measurement"; (2) "Measurement Units"; (3) "Introduction to Chemistry"; (4) "The Periodic Table"; (5) "What is Inside an Atom?"; (6) "Bonding"; (7) "Formulas and Equations"; (8) "The Bursting Atom"; (9) "Relationships…

This book provides a basic introduction for the student to hazardous materials chemistry. Coverage of chemistry, rather than non-chemical hazards, is particularly stressed on a level which the layman can understand. Basic terminology is emphasized at all levels, as are simple chemistry symbols, in order to provide the student with an introductory…

A concept-map assessment consists of a task that elicits structured knowledge, a response format, and a scoring system. Variation in tasks, response formats, and scoring systems produce different mapping techniques that may elicit different knowledge representations, posing construct-interpretations challenges. This study examined two mapping…

This study investigates and compares American and Chinese secondary students' science achievement, their attitudes toward science, and other factors influencing science learning. The subjects, in Grades 7-12, include Chinese students (N=495) and American students (N=469). A survey of attitudes towards science developed by the authors was employed…

This paper reports on an interdisciplinary theoretical framework for the characterization of models and modeling that can be useful in application to chemistry education. The underlying argument marks a departure from an emphasis on concepts that are the outcomes of chemical inquiry about how knowledge growth occurs through modeling in chemistry.…

This study presents a quantitative method for scoring concept maps generated by students learning introductory college chemistry. Concept maps measure the amount of chemical information the student possesses, reasoning ability in chemistry, and specific misconceptions about introductory and physical chemistry concepts. They provide a visualization…

This document reviews the literature in the collections of the Library of Congress on electric vehicles. Not intended as a comprehensive bibliography, this guide is designed as the title implies, to put the reader "on target." This is of greatest utility to the beginning student of the topic. (AA)

The purpose of this investigation was to identify and describe the differences in the methods used by experts (university chemistry professors) and nonscience major introductory chemistry students, enrolled in a course at the university level, to solve paired algorithmic and conceptual problems. Of the 180 students involved, the problem-solving…

Presented are two studies examining effects of using expressive writing in the science classroom. The first study, "Writing to Think About High School Chemistry," was conducted by a high school English teacher who enrolled in a high school chemistry course. The course was typical with the exception that students were encouraged to keep a…

This report, which examines expected major trends in ocean research up to the year 2000, focuses on the most important ocean research problems that should receive particular attention during the next decades, what major advances should be expected and what kinds of research should be encouraged for them to be achieved, and impediments to achieving…

Examines the effect of three different modes of task orientation on observational attainment in practical chemistry. Results include the overall performance on the chemistry observation test and an analysis of the influence of the complexity of observational tasks on observational attainment. (Author/GS)

Presents a set of integrated experiments for the undergraduate inorganic chemistry laboratory, designed with the belief that a related set of syntheses, reactions, and characterization techniques sums to a greater learning experience than an equal number of unrelated experiments. (MLH)

Describes the apparatus of a chemistry kit that also contains a pupil's manual and a teacher's guide. (LS)

Describes a supplementary first-year chemistry course offered to selected students also enrolled in the regularly scheduled first-year chemistry course.
