Reviews the life of Sir Isaac Newton, stressing his contributions to science and society. (CS)

Examines 24 revolutionary scientific figures mentioned in the "Structure of Scientific Revolutions" to determine whether young scientists are more likely to make revolutionary discoveries than older scientists. Suggests that middle-aged scientists are responsible for initiating more scientific revolutions than young scientists given the proportion…

Many in the science education community identify Kuhn with a sociological approach as opposed to a philosophical approach. Attempts to liberate Kuhn from too close an association with the sociology of scientific knowledge. (Author/CCM)

Discusses the nature of science education as an essential aspect of the phase-model of scientific development. (Author/CCM)

An experiment that can be used to directly study the local chemical environments of phosphorus in solid amorphous materials is demonstrated. The experiment aims at familiarizing the students of chemistry with the principles of solid-state NMR, by having them synthesize a simple phosphate glass, and making them observe the (super 31)P NMR spectrum,…

A theoretical analysis of single-slit diffraction based on the Fourier transform between coordinate and momentum space is presented. The transform between position and momentum is used to illuminate the intimate relationship between single-slit diffraction and uncertainty principle.

Exfoliated-compressed graphite materials are examined. A chemical explanation for the pseudo-exfoliation phenomenon is proposed.

There are numerous studies in literature related to the use of cartoons in physics, chemistry and mathematics education. However the studies on the use of cartoons as an alternative assessment tool are highly limited. This study was concerned with the use of cartoons as an alternative assessment method. There were five cartoons prepared related to…

Drawing on historical research, this paper draws attention to Dewey's oft-neglected, but no less brilliant work published in 1929, The Sources of a Science of Education. Dewey's critique of efforts in his day to seek "quick-fixes" to practical educational and curricular issues by employing premature scientific investigations and findings has…

This edited collection synthesizes current research on the most promising methods and models for designing coherent science instruction. Arising from the National Science Foundation-funded Delineating and Evaluating Coherent Instructional Designs for Education (DECIDE) project, this volume combines the insights of researchers from two Centers for…

The graduate of the Field Heat Treatment Technician apprenticeship program is a certified journeyperson who will be able: (1) use heat treatment equipment to apply heat to materials in order to change a material's properties; (2) Use their knowledge of the properties of heat, industry codes and specifications to determine how heat treatment will…

The focus of research in technology education has evolved throughout its history as the field changed from industrial arts to technology education (Spencer & Rogers, 2006). With the move to technology education, the field has begun to broaden its focus to better understand the teaching, learning, curriculum, and policy implications of preparing…

The aim of this study was to elicit students' conceptions about big bubbles in boiling liquids (water, ethanol and aqueous CuSO[subscript 4] solution). The study is based on twenty-four students at different ages and grades. The clinical interviews technique was conducted to solicit students' conceptions and the interviews were analyzed to…

In one of the classic free-fall experiments, a small mass is attached to a strip of paper tape and both are allowed to fall through a spark timer, where sparks are generated at regular time intervals. Students analyze marks (dots) left on the tape by the timer, thereby generating distance-versus-time data, which they analyze to extract the…
