Presents a procedure used in sophomore level organic chemistry which has been particularly useful for organic qualitative analysis. Uses a nine-well spotplate and one-two mg of solid and three-four drops of eight different solvents. Solubility is checked at different temperatures. Provides a solubility table. (MVL)

Describes an experiment to determine the density of air within a 10 percent error range using a basketball and a triple beam balance. Provides the typical data and a graph. (YP)

In this second part of an article on affective research in environmental education, nine recommendations for the improvement of environmental education in the affective domain are provided. A four-step approach is stressed. Listed are 15 references. (CW)

Examines the relationship between science locus of control (SciLOC) orientation and attitudes toward teaching science among 104 preservice elementary school teachers. Path analysis of the proposed causal model accounts for 57 percent of the variance in expressed attitudes and 11 percent of the variance in SciLOC orientation. (Author/YP)

Describes the nature of cognitive research. Misconceptions research in mechanics and electricity are reviewed. Research results on expert/novice differences in knowledge organization and problem solving are reviewed. Implications for classroom teaching are discussed. Lists 34 references. (YP)

Describes three demonstrations: (1) "A 'Rocket' Cart" (using a fire extinguisher and a child's truck); (2) "Angular Momentum Conservation" (providing materials and calculations); and (3) "Cavendish Experiment" (including the building method and examples of calculations). (YP)

Discusses the calculation of free energy in reactions between silicon dioxide and carbon. Describes several computer programs for calculating the free energy minimization and their uses in chemistry classrooms. Lists 16 references. (YP)

Provides some significant figure rules used in chemistry including the general theoretical basis; logarithms and antilogarithms; exponentiation (with exactly known exponents); sines and cosines; and the extreme value rule. (YP)

Surveyed is a pre-physician assistant program by giving: definition of the career, a historical basis, medical practice settings, education, advantages, and an evaluation of the student population. Included is a table which shows the distribution of acceptances into the physician assistant programs for the medical and clinical phases of training.…

Describes a lesson in which instruction is initiated through the right cerebral hemisphere by using visualizations as concrete aids to learning. Explanations include a hand model which is used to illustrate the dynamics of guard cell activity of stomates and a paper folding model to show increase in surface area. (RT)

Provided is information on stipends from the last 3 surveys for 12 engineering disciplines. Notes that in 1987-88 the highest GTA and GRA stipends were awarded in the same field; materials science/metallurgical engineering. (MVL)

Reports that 26 of 199 responding colleges require the Fundamentals of Engineering examination. States that of the 26, 16 require it to be taken college-wide and 3 require the student to pass. It was estimated that fewer than half of all graduating engineering students take the exam. (MVL)

A procedure where homework assignments are collected, graded, and returned each week is suggested. Students were used to grade each other's homework against copies of the solutions according to criteria established at the beginning of the course. Student response has been positive. (MVL)

Discusses three broad classes of magnetic behavior: diamagnetic, paramagnetic, and ferromagnetic. Presents a simple lecture demonstration using an overhead projector to synthesize triiron tetraoxide and to show its interaction with a magnetic field and comparing it to a paramagnetic material. (MVL)

Described are the technology training principles, student selection, program content, postgraduate program, graduate program, undergraduate program, and expenses of the Nokia Group in Finland. (YP)
