Describes three criteria for evaluating educational software; classification of software types, the presence or absence of process skills, and educational practices. This article provides background for a software evaluation form to appear in a subsequent issue. (CW)

This Evaluation Brief examines the BSCS approach to improving secondary science education, and illuminates some of the lessons learned from its five years of work with districts across the nation. It highlights selected findings from the full study report and discusses the broader implications for the field. Specifically, this Brief examines the…

Assesses the current state of computer-assisted instruction in schools. Reviews educational issues of teacher productivity, teacher preparation, software selection, and curriculum integration. Examines legislative actions directed at greater computer use in classrooms. (JM)

Provides a brief account of the discovery and theory of antimatter and describes several activities relevant to the study of antimatter on the secondary level. (MLH)

Boyle's Law and basic relationships between volume and pressure of a gas at constant temperature are presented. Suggests two laboratory activities for demonstrating the effect of temperature on the volume of a gas or liquid. (CS)

A new system for the experiments on intermolecular forces is presented in the interest of laboratory safety. (GS)

Described is a novel approach to the teaching of projectile motion of sixth form level. Students are asked to use an analogue circuit to observe projectile motion and to graph the experimental results. Using knowledge of basic dynamics, students are asked to explain the shape of the curves theoretically. (Author/MA)

Analyzed and classified were Individualized Science Instruction System (ISIS) minicourse performance objectives and criterion-referenced test items according to Bloom's cognitive "Taxonomy" to determine levels of cognition emphasized. The findings indicate that ISIS minicourse test objectives are written primarily at the knowledge and…

Describes how to collect micrometeorites and suggests a number of related activities such as determining the number of meteors entering the atmosphere and determining the composition of the micrometeorites. (BR)

Describes some functional group interconversions that can be carried out on a small scale. The reactions are examples of transformations found in A-level, ONC and HNC courses for British chemistry students. (Author/GS)

A sample run of a program intended for use by students with access to a teletype or visual display computer is shown. The program is satisfactory for the testing of the law for up to about 20 generations using any valid set of frequencies for genotypes. (AJ)

In this insect morphology exercise, students study the external anatomy of the worker honeybee. The structures listed and illustrated are discussed in relation to their functions. A goal of the exercise is to establish the bee as a well-adapted, social insect. (MA)

Suggests a study of plant dyes as a way of stimulating student interest and enthusiasm; provides an example of a student report on this subject. (GS)

Explains the separation of the constituents of mixtures on one piece of chromatography paper. The example presented involves a vitamin C tablet, a disprin tablet, and a glucose tablet. Outlined are two methods for separating the constituents. (GS)
