THREE APPROACHES TO INSERVICE TEACHER EDUCATION WERE EXAMINED TO DETERMINE WHICH WAS MOST EFFECTIVE IN PREPARING TEACHERS TO USE A NEW CURRICULUM IN SCIENCE. THE CURRICULUM, "SCIENCE - A PROCESS APPROACH," HAD BEEN DEVELOPED THROUGH EFFORTS OF THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE FOR SCIENCE INSTRUCTION IN GRADES K-3.…

An instructional television program, "Place of Doors," developed by the New York State Education Department's Bureau of Educational Communication to teach science, ecology, health, social studies, and consumerism to fourth graders was evaluated. The program was used to provide mainline rather than supplemental instruction. Nine hundred…

This handbook is designed to assist teachers of technical mathematics in developing practically-oriented curricula for their students. The underlying assumption is that, while technology students are not a breed apart, their needs and orientation are to the concrete, rather than the abstract. It describes the nature, scope, and content of…

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)

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 consider students' pre-existing conceptual schemes when teaching chemistry. Reports on a study done in Spain which indicates that the existence of adolescents preconceptions about gases is important to consider when teaching the principles of conservation of substance, mass, and weight. (TW)

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)

Reviews the purposes, underlying assumptions, and curriculum development model for the United Kingdom's "Children's Learning in Science Project." Explains the general features and phases of the constructivist approach to learning that the program advocates. Identifies theoretical developments on children's ideas, the constructivist view…

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…

Describes a program for sixth grade students developed by the Methacton School District (Norristown, PA) Planetarium staff. Provides brief outlines of eight teaching units designed to provide students with hands-on activities in astronomy. Includes a reproducible worksheet for an activity which involves students in creating and decoding…
