Intentional, conscious speech is composed of both scientific and artistic components and thus requires instruction from both perspectives. Teachers often employ nonvalidated propositions--derived from personal and vicarious experience, results of scientific investigations, or folk wisdom--to advise students on speech performance. Care must be…

An analysis of classroom discourse is reported in which the use of questions by science teachers is assessed in terms of arguments to establish knowledge claims. Questions are analyzed not for their form or frequency but for their function in the development of arguments which establish claims rationally. Seen in the context of rational argument,…

TO DETERMINE THE RELATIVE IMPORTANCE OF CHEMISTRY AND PHYSICS FOR INSTRUCTION IN ELECTRICAL AND ELECTRONIC TECHNOLOGY, 51 TECHNICAL WORKERS, 51 JUNIOR COLLEGE INSTRUCTORS, AND 11 EXPERTS RATED 240 SCIENTIFIC PRINCIPLES AS TO THEIR VALUE IN A TECHNICIAN'S WORK. THE THREE GROUPS AGREED ON THE RANK ORDER OF 15 TOPICS--(1) CURRENT ELECTRICITY, (2)…

The changes which occurred in man's view of the solar system from the time of Ptolemy to that of Galileo are presented. Contained is a brief review of the chain of events which resulted in the acceptance of a heliocentric system. Ptolomy's theory is described and a diagram illustrates the paths of the epicycle of Mars according to his geocentric…

This volume contains chapters 19 to 25 of the ACS "Modern Chemical Technology" (CHemTeC) curriculum material which is intended to prepare chemical technologists. Laboratory techniques and procedures are emphasized. The chapters cover the areas of the techniques of sampling, the techniques of weighing, sample preparation, the measurement of pH,…

Semiotic research increasingly reveals the basic importance of structure at all levels of genetic, linguistic, and social process. The paradox that structure not only liberates but also imprisons has been familiar to members of many different cultures, and the search for personal release in transcendent states of feeling contrapuntally illuminates…

The two student notebooks in this set provide the basic outline and assignments for the fourth and last year of a senior high school unified science program which builds on the technical third year course, Science IIIA (see SE 012 149). An introductory section considers the problems of survival inherent in living systems, matter-energy…

The two student notebooks in this set provide the basic course outline and assignments for the first year of a four year senior high school unified science program. The first volume consists of these three units: The Universe and Man; Man's Attempt to Understand and Relate to the Process of Change; and Man's Ideas About the Structure of Matter.…

The purpose of this essay is to examine some of the major similarities and differences between science and religion, as well as to attempt a synthesis to resolve what is more an apparent rather than a real contradiction of the two disciplines. The rationale for such an undertaking is based primarily upon the need for explicit definition and…

Discusses teaching the nature of science as well as teaching the subject matter of science. (SL)

Numerous science and mathematics activities which can be performed with sporks (plastic spoon-forks) that are packaged in cellophane with a napkin and a straw and distributed with school lunches are described. (CP)

Peer-reviewed, classroom-tested, and tailored specifically for introductory science courses, Favorite Demonstrations is a complement to every college instructor's lesson plans. The book is an all-in-one compilation of 36 popular classroom demonstrations published since 1993 in the "Favorite Demonstration" column of NSTA's Journal of College …

The purpose of this paper is to explore the possibility of using the principle of "superposition of states" (commonly illustrated by Schrodinger's Cat experiment) to understand the process of using standardized testing to measure a student's learning. Comparisons from literature, neuroscience, and Schema Theory will be used to expound upon the…

The second-year, shared experience curriculum for Iowa Wesleyan College, Mount Pleasant, Iowa is an Integrated Science course linking science and art. The Integrated Science Linking Science and Art promoted a better understanding of basic scientific principles and literacy, by initially showing linkages to art. As the course developed, it became…
