The collection of primary data in laboratory classes enhances undergraduate practical and critical thinking skills. The present article describes the use of a lecture program, running in parallel with a series of linked practical classes, that emphasizes classical or standard concepts in exercise physiology. The academic and practical program ran…

Making connections is an emerging education theme of the 21st century. Science teachers are encouraged to connect new learning with prior knowledge, learning with student interests and experience, and classroom activities with the history and nature of science. Strategies that facilitate these connections enrich and enhance instruction. In this…

This case study examines the alignment between the Intended Curriculum, Implemented Curriculum and Achieved Curriculum of a fourth grade inquiry based unit, "Food Chains and Webs." Specifically addressed are how the curriculum was modified to meet state standards, how teachers were trained, and how assessment of curricular implementation was…

The purpose of this study was to investigate the impact of a summer science camp teaching experience on preservice elementary teachers' science teaching efficacy, science content knowledge, and understanding of the nature of science. Master's degree students enrolled in the elementary Fairfax Partnership Schools (FPS, n = 21) cohort served as the…

A previous study showed that elementary teaching majors enrolled in an inquiry-based physical science course developed chemistry content knowledge comparable to that of students enrolled in traditional lecture-based courses. This current study compares the views of these elementary teaching majors regarding how chemistry is taught and learned to…

This book shows how physics relates to daily life. Chapters included are: (1) "Physics of Fun" (dealing with the concepts of friction, Bernoulli's principle, lift, buoyancy, adhesion, cohesion, surface tension, gas expansion, waves, light, mirror images, and solar cells); (2) "Physics of Nature" (illustrating the concepts of inertia, static…

A reaction kinetics experiment for the chemical engineering undergraduate laboratory course was developed in which in-situ Fourier Transfer Infrared spectroscopy was used to measure reactant and product concentrations. The kinetics of the hydrolysis of acetic anhydride was determined by experiments carried out in a batch reactor. The results…

The impact of science on society is examined in this publication's coverage of a series of public lectures that commemorated the 25th anniversary of the National Aeronautics and Space Administration. Edited versions of four speeches are presented which address the impact of science on society from the time of humanity's first significant…

The teaching of science in the K­-12 classroom has been less than successful. Students typically do not develop science literacy and do not understand the role and relevance of science in society. Inquiry­-based learning is an approach which promises to improve science teaching by engaging students in authentic investigations, thereby achieving a…

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…
