Outlines a variety of laboratory procedures, discussions and demonstrations including the preparation and analysis of a square planar copper (11) complex, thermit reactions in a sand mould, product solubility, an aid for learning common oxyanions, thermal decomposition of nitric(v) acid. and nine others. (GS)

Outlines a variety of laboratory procedures, discussions, and demonstrations including a no-solder circuit board, damped to maintained oscillations with L-C circuits, polaroid strobe photos, resistive putty, soldering and circuit checking exercise, electromagnetic radiation, square pulses in C-R circuits, and testing an oscillating system. (GS)

Presents notes on the objectives of laboratory instruction, the design of assessment systems on the principles of criterion-referenced measurement, student ability to measure, and student attitudes toward the importance of physics. (GS)

Presents arguments for and against the viewpoint that the teaching of chemistry and of physics should fall in line with modern mathematics. Concludes that modern mathematics has been beneficial in some respects and harmful in others. (CS)

Presents examples of combination, decomposition, replacement metathesis, and neutralization chemical reactions. Suggests that students will gain knowledge of some general trends in the chemical properties of the main group and transition elements by examining reaction types. (JN)

Discusses the use of games to facilitate learning scientific concepts and principles. Describes the Cell Game, which simulates plant and animal cells; the Energy Quest, which requires players to buy property that generates largest amounts of electricity; the Blood Flow Game, which illustrates circulation of blood through the human body. (CS)

Describes a one-dimensional model for an ideal gas to study development of disordered motion in Newtonian mechanics. A Monte Carlo procedure for simulation of the statistical ensemble of an ideal gas with fixed total energy is developed. Compares both approaches for a pseudoexperimental foundation of statistical mechanics. (Author/JN)

Describes method for locating images in simple and complex systems of thin lenses and spherical mirrors. The method helps students to understand differences between real and virtual images. It is helpful in discussing the human eye and the correction of imperfect vision by the use of glasses. (Author/SK)

Describes an exercise involving the use of kinematics to decide if one should stop or try and get through an intersection when the traffic light turns yellow. Gives students' experience in recording data, doing simple calculations and connecting classroom studies to real world experiences. (Author/SK)

Reports the results of a survey of practicing scientists, recent graduates, and undergraduates about their perceptions of undergraduate laboratory programs in biology, chemistry, and physics. Scientists and graduates regard laboratory experiences in pragmatic terms stressing the scientific process skills while undergraduates regard laboratories as…

The Australian Web of Life biology course is evaluated as to its philosophy and mode of instruction. The study reveals that the use of inquiry-oriented practices is relatively low and that teachers consider the objectives of the course more important than do their classes. (Author/DS)

Describes the use of a microcomputer in studying a model experiment (Brownian particles colliding with thermal particles). A flow chart and program for the experiment are provided. Suggests that this experiment may foster a deepened understanding through mutual dialog between the student and computer. (SK)

Investigates the effects of teaching 120 first grade children specific strategies for nonvisual seriation on their performance on post-tests and retention tests. Results show that simple seriation can be learned and retained. (HM)

Describes the mandatory continuing education requirements, for professional engineers that have been enacted into law in some states. The requirements could be satisfied by taking a certain number of professional development hours (PDH), continuing education units (CEU), or any other activities acceptable to the state board. (GA)

Presents an experiment which uses readily available starting materials and inexpensive equipment for synthesis of transition metal carbonyls at 1000 atm and which is intended to give students experience in techniques used in research and industry. Safety precautions are emphasized. (Author/SA)
