Approximately 30 experiments related to environmental problems comprise this manual. The three conceptual themes under which these lessons are organized deal with: (1) change; (2) the interaction of custom, rule, and law in society; and (3) economy, life style, and individual attitudes. Provided are materials for both students and teachers.…

This is a guide for introductory college chemistry students who are new to the subject of chemistry and who have been exposed to linear and second-order algebra equations and the concept of slope. The guide presents directions on the following topics: (1) How to prepare for lectures and take notes; (2) How to study chemistry outside of class using…

The gain in chemistry knowledge made by high school chemistry students whose cognitive patterns were similar to those of their teachers was compared to the gain of students whose cognitive patterns differed from their teachers'. Seven cognitive factor tests were administered to 13 teachers who were participating in three Chemical Education…

The purpose of this study was to determine how students' perceptions of the proportionality schema are related to achievement in introductory chemistry. A total of 309 tenth-grade students, comprised of an ALCHEM materials sample (N=168) and a CHEM study sample (N=141), enrolled in four urban senior high schools, was tested under normal classroom…

This is one of several short-term courses developed to assist in the training of waste water treatment plant operational personnel in the tests, measurements, and report preparation required for compliance with their NPDES Permits. This Staff Guide provides step-by-step guidelines on course planning, development and implementation involving…

This paper summarizes what the author considers to be the best advice available at this time for applying Piaget's theory in the chemistry classroom to understand the difficulties that some students have. The identification of students who are operating at the concrete operational or formal operational level is discussed along with the actual…

This manual reviews chlorination practices in the treatment and disposal of wastes from the earliest known applications. The application of chlorination for various purposes is described but no attempt has been made to compare chlorination with other methods. Included are chapters on the development and practice of wastewater chlorination,…

This manual is designed for use by instructors who will have to teach others the basic laboratory skills needed to perform National Pollution Discharge Elimination System (NPDES) Analyses. It includes topics related to the presentation of training courses in which the NPDES analyses would be taught. These topics include: examples of course…

This publication is the fourth of a series of seven supplementary investigative materials for use in secondary science classes providing up-to-date research-related investigations. This unit is structured for grades 9 through 12. It deals with physical factors that affect color changes in plant foods during processing and in the preparation of…

This study, part of an instructional development project, explores the effects of three different representations of functional algorithms in an introductory chemistry laboratory. Intact classes were randomly assigned to a flowchart, list, or standard prose representation of the procedures (algorithms). At the completion of 11 laboratory sessions,…

This document provides computer programs, written in BASIC PLUS, for presenting fundamental or remedial college chemistry students with chemical problems in a computer assisted instructional program. Programs include instructions, a sample run, and 14 separate practice sessions covering: mathematical operations, using decimals, solving…

Presented is a manuscript for an introductory boiler water chemistry course for marine engineer education. The course is modular, self-paced, audio-tutorial, contract graded and combined lecture-laboratory instructed. Lectures are presented to students individually via audio-tapes and 35 mm slides. The course consists of a total of 17 modules -…

Presented is a report of a program of the American Society for Metals, designed to introduce materials science principles via solid state chemistry into high school chemistry courses. At the time of the inception of this program in the mid-sixties, it was felt that high school students were not being adequately exposed to career opportunities in…

The activities comprising the career education resource guide explore careers in chemistry or chemistry-related fields with limited treatment given to other science-related occupations. Units providing a general framework of chemical principles and related activities alternate with the career units. The career concepts most applicable to each unit…

The primary objective of this study was to determine the characteristics that should constitute an auto-tutorial program in first-year general chemistry at the junior college level. Specifically, this study was concerned with developing an auto-tutorial model for a first-year general chemistry class at Claremore Junior College using the derived…
