Describes and evaluates one assignment from a unit designed to teach basic science concepts and instructional strategies to primary school teachers, specifically, the control of variables. (SK)

Discusses how the concept of organoleptic chemistry permeates every modern chemical experiment. Six approaches for developing organoleptic attitudes which are crucial to the experimental aspects are also presented. (HM)

Describes a new pedagogical approach to electromagnetic theory, in which the displacement current and the Galilean relativity principle are introduced before discussion of the Faraday induction term. Rationale for the alternate order of introducing these concepts and laws is explained, relative to their historical development. (CS)

Describes simulation games involving random phenomena concepts. Reviews the role of such games in teaching abstract scientific concepts. (SK)

Freshmen college students (N=290) were asked, "What is an atomic orbital?" as a measure of their knowledge after completing high school chemistry. Results suggest that high school chemistry be divided into two levels: (1) procedures and interpretations of classical chemistry and (2) introduction of elementary quantum chemical concepts.…

Describes an undergraduate experiment which measures the energy gap in silicon and germanium. Theory, procedure, and results of this experiment are included. (HM)

Discusses the simplest three-body problem, known as Euler's problem. The article, intended for students in the undergraduate mathematics and physics curricula, shows how the complex equations for a specific three-body problem can be solved on a small calculator. (HM)

Reported is a study designed to determine conceptualizations of scientific concepts, laws and theories (linguistic structure of science) held by 80 Kwara State, Nigeria, secondary school science teachers relative to conceptualizations identified with seven philosophers of science. (Author/DS)

Presents three simple distinct operational procedures for transforming the empirical notion of speed into a formal concept. The relationship between these three procedures and Galilean velocity and Einsteinian relativity is also included. (HM)

The motivation and interpretation of the Fizeau experiment are reviewed, and its status as a test of special relativity is discussed. It is shown, with the aid of a simplified, purely mechanical model of the propagation of light in matter, that the experiment actually cannot discriminate between Galilean and relativistic kinematics. (Author/SK)

Discusses a method used at DePaul University of Chicago, Illinois, in a relativity course for students who are not science majors, emphasizing logical reasoning rather than memory of facts. (HM)

Discusses how the frequency domain (line widths) and time domain (coherent optical transients) are related to the concept of transverse relaxation time in the study of high resolution optical spectroscopy. (HM)

Presents the first of a series of articles that discuss the perception of sound and music. This series of articles is intended to provide an introduction to the broad subject of high-fidelity sound recording and reproduction. (HM)

The experiments described in this article discuss the versatility of the linear variation method in quantum chemistry and the ease with which it can be used with a simple computer program. (SA)

Describes laboratory experiments of a chemistry course on advanced process control. The equipment for the process around which these experiments were developed by the University of Louisville was constructed from data provided by Exxon Oil Company. (HM)
