This experiment, mixing solutions of potassium iodide and lead nitrate to give a bright yellow lead iodide precipitate, often leads students into other topics such as making paint from the precipitate. (BB)

Investigates how student ability, anxiety level, question wiseness, and relative difficulty of questions influence students' opinions of and performance on a chemistry examination. Examines strategies employed by students in selecting questions. Concludes that the major problem for test candidates is anxiety. (Author/DB)

Reviews exercises in the analysis of samples and interpretations of results from the geochemical survey portion of a three year teacher education program in geology presented at Salisbury College of Advanced Education. (SL)

Reports the results of an investigation of sex stereotyping in 17 high school chemistry textbooks. Results indicate definite sex bias in all books reviewed with a greater portrayal of male roles and activities. (SL)

Described are a method of cultivating Euglena, a method for presenting and solving mole equations, and a design of a simple solar collector. (SL)

The validity of the Test of English as a Foreign Language was examined in relation to prediction of success of fifty Asian students in engineering, chemistry, or mathematics. The test was significantly correlated with grade point average. (Author/JKS)

Summarizes the Ising model of ligand binding as it applies to cooperative binding to long chain molecules. Also presents some illustrations which help to visualize the connection between the interaction parameters and the shape of the binding isotherm. (Author/MR)

A precise method of determining absorption maxima where Gaussian functions occur is described. The method is based on a logarithmic transformation of the Gaussian equation and is suited for a mini-computer. (MR)

Identifies specific content changes in secondary school chemistry courses since 1968 and evaluates the reform in terms of student achievement by each grade level. (AV)

Recommends that high school students be taught about interdisciplinary relationships among the sciences, specifically chemistry and physics. Explains how schools can coordinate class schedules and course content to complement learning in both sciences. (AV)

Presents four science experiments for the junior high level relating to electric switches, a chemical card game, combustion energy, and chromatography. (SL)

Safety checklists (week, term, annual) for secondary school science departments are provided. (CP)

Describes a computer simulation of reaction kinetics in atmospheric photochemistry. (SL)

Describes a nuclear and radiation chemistry course offered to second and third year students at the University of New South Wales, England. (SL)

Reports the construction and field testing of an electronic device intended to serve as a replacement for Piaget's first chemical task. Validity of the electronic task was established in testing 64 secondary school age students. Results obtained by the chemical and electronic tasks were highly correlated. (CP)
