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…

Reviews the initiatives taken by six states in promoting precollege Science, Technology, Society (STS) education. Discusses the exemplary efforts undertaken in Florida, Maryland, Michigan, New York, Washington, and Wisconsin. (ML)

Differentiates between problems, exercises and algorithms. Discusses the role of algorithms in solving problems and exercises in chemistry. Suggests that very real differences exist between solving problems and exercises, and that problem solving steps can be and should be taught in chemistry education. (TW)

Describes a spreadsheet computer program which can be used with an Apple Macintosh computer to perform a multitude of calculations. Discusses two types of calculations taught in general chemistry. Demonstrates how to use the spreadsheet to calculate mass percent and the formula of a compound. (TW)

Discusses the concept of "science for all" as it has applied to curriculum reform movements in Great Britain. Enumerates areas in science education that are in need of improvement and outlines important aspects of a coherent science curriculum. Suggested are several implications for the learning and teaching of science. (CW)

Reviews the history of alchemy including personalities and methods. Discusses the philosophy associated with various early chemists and alchemists. Attempts to show that it was not unreasonable for ancient alchemists to believe in the possibility of transmutation. (CW)

Discusses the use of a microcomputer in the assessment of middle school pupils in science classes. Describes experimental details, the computer program, test procedures, and results. Concluded that pupils benefit from the immediate feedback provided by computer assessment compared to traditional methods. (CW)

Introduces the unique interfacing equipment for measuring muscle strength over time. Explains the materials, setup method, operation, and typical display. Suggests other activities with which to utilize this device. (YP)

Discusses the main objectives of ecohistory and sources of information for this study. Details five themes that are important for students to know about the history of ecology including the history of Earth, fauna and flora, the human species, human civilization, and changes in the human environment. (CW)

Describes the procedures used to demonstrate transpiration with the common sunflower. Discusses the results expected from such an activity. Provided is a sample data sheet. (CW)

Presented is a sample hybridoma assay which can be used in a research or classroom laboratory setting for instructional purposes. Described are experimental methods, materials, and observations made during this activity. (CW)

Suggests a way to change the role of physics teacher. Discusses the teacher as a coach, reducing anxiety, team cooperation, and a grading system including "forgiving learning" which recognizes student's progress. (YP)

Presents examples to show the ubiquitous nature of geometry. Illustrates the relationship between the perimeter and area of two-dimensional objects and between the area and volume of three-dimensional objects. Provides examples of distribution systems, optimum shapes, structural strength, biological heat engines, man's size, and reflection and…

Suggests that the process view of science is flawed. Argues that (1) it is superficial and misleading to portray the method of science in process terms; (2) many of the processes have no special association with science; and (3) there is no evidence that performance is improved. Speaks of the challenge facing science education. (RT)
