This study was designed to assess the effects of the problem-oriented method compared to those of the traditional approach in general chemistry at the college level. The problem-oriented course included topics such as air and water pollution, drug addiction and analysis, tetraethyl-lead additives, insecticides in the environment, and recycling of…

The purpose of this research was to develop hierarchies of behavioral objectives for the chemistry content of a one-semester course in physical science for preservice associate degree nursing students. Each of three content objectives was expressed by a series of behaviorally stated objectives which included a terminal objective for a unit of…

The purpose of this study was to design a course and to determine its effects on learners' perceptions of certain scientific literacy concepts. A science-related semantic differential instrument was used. Student-instructor collaboration resulted in the selection of objectives and learning strategies in order to establish an environment favorable…

Described is the Wyndham science component of the program designed for the six years of secondary schooling for students in New South Wales, Australia. A subjective evaluation of the program and suggestions for improving course materials and teaching are given. There are six major sections in the report: (1) a general outline of the structure and…

This resource guide is an update, covering the years 1970-1973, to a compendium of astronomy educational materials published in 1970. Included are English-language materials of all kinds, and at all levels, which would be of interest in astronomy education. The materials are classified according to type and are graded according to level where…

Lists 40 things to do to have a safer chemistry laboratory. Discusses the evolution of these guidelines for schools from safety suggestions originally developed by industry. Categorizes the 40 steps into those requiring minimal cost and those requiring moderate expense. (TW)

Compares the amount of research being published by personnel from 37 undergraduate institutions of higher learning during the 1970's with the amount published from 1980-1985. Lists the number of student co-authored publications in chemistry from the leading 11 institutions for 1980-1985. (TW)

Discusses the properties of carbon dioxide in its solid "dry ice" stage. Suggests several demonstrations and experiments that use dry ice to illustrate Avogadro's Law, Boyle's Law, Kinetic-Molecular Theory, and the effects of dry ice in basic solution, in limewater, and in acetone. (TW)

Proposes that preparative chemistry is an important and integral part of chemistry as a whole, and an excellent way to introduce students to descriptive chemistry. Provides an outline for students to follow for converting and transforming salts. Suggests a set of general guidelines for studying anion and cation transformations. (TW)

Describes a microcomputer program that can be used in teaching the basic physiological aspects of acid-base (AB) balance. Explains how its game format and graphic approach can be applied in diagnostic and therapeutic exercises. (ML)

Discusses the need to develop laboratory practical examinations in chemistry which attempt to measure students higher order thinking skills and conceptual understanding rather than simply their laboratory skills. Examples of examination questions being used in general chemistry laboratory courses at the State University of New York at Cortland are…

Describes a chemistry experiment where an alkaline ice-cold permanganate solution is reduced by adding dropwise a cold diluted hydrogen peroxide solution. Outlines the course of the reduction through the various oxidation states of manganese with their characteristic colors. (TW)

Outlines an approach to chemistry experiments designed to help students appreciate the importance of each step in an experimental procedure. Describes an experiment involving Charles's Law to illustrate this idea. (TW)

Describes an undergraduate biochemistry course required to be taken by all students at Beijing Medical University. Provides the outline of the lectures and the specific content areas covered by them. Stresses the need for students to know the biochemical literature and to think scientifically. (TW)

Discusses some of the problems associated with requiring a highly structured set of laboratory exercises in undergraduate biochemistry courses. Describes a program where students perform short-term independent projects after completing experiments which introduce basic concepts and techniques. Provides lists of the experiments and some typical…
