Faculty from various disciplines were interviewed to determine their attitudes toward computer-based education (CBE). Experience with computer grading of tests and use of objective tests, coupled with the fact that two-thirds of the faculty members had direct/indirect experience with CBE, indicate a base of knowledge conducive to use of CBE.

Presents highlights of the Seventh International Conference on Chemical Education as reported by a high school chemistry teacher who attended the conference. Tables showing the secondary school structure in Belgium, China, England/Wales, France, Kenya, South Africa and Switzerland are included. (JN)

Describes a quantitative evaluation of an interactive videodisc program in which students measure the temperature dependence of the solubility product of lead chloride by titration of chloride with silver nitrate using a Mohr titration. Student reaction (based on responses made using the program, quiz answers, and laboratory performance) was…

Describes a chemistry course designed, in cooperation with local public school districts, to intellectually challenge a group of 8th, 9th, and 10th grade students. Organic chemistry and biochemistry are integrated into the course (titled Chemistry and Everyday Life) to emphasize practical applications of chemistry. The course syllabus is included.…

A special five and one-half year program for training upper secondary school chemistry teachers has been developed and tested over the past decade at Roskilde University near Copenhagen. The program (which emphasizes project work) and a student project on epoxy glue are described. Program graduates are generally problem-oriented and…

A pilot project was initiated in 1979 at the University of Delhi to develop low-cost, locally produced science equipment. This article: (1) describes the pilot project; (2) presents examples of the low-cost equipment produced; and (3) discusses how the approach used rather than the equipment developed is disseminated. (JN)

Background information, materials needed, and procedures used are provided for potentiometric fluoride, halide, orthophosphate, and sulfate titrations. Typical results obtained are also provided for each type of titration. (JN)

Describes the use of an inexpensive apparatus (based on a butane lighter fluid can and a standard tire pressure gauge) in measuring the atomic/molecular mass of an unknown gas and in demonstrating the mass of air or the dependence of pressure on the mass of a gas. (JN)

Presents a buffer demonstration which features visualization of the effects of carbon dioxide on pH. Background information, list of materials needed, procedures used, and a discussion of results obtained are included. (JN)

Describes an experiment which requires only qualitative observations, is suitable for general chemistry students, prompts an understanding of thermodynamic spontaneity, gives chemical meaning to electrode potentials, requires non-electrochemical equipment, and allows estimates of the standard potential for the reduction of Vanadium (V) to V (IV).…

Background information, procedures used, and typical results obtained are provided for a simple homogeneous precipitation preparation of chromium(II) acetate. (JN)

Describes the equipment, procedures, and results for the determination of caffeine in beverages by high performance liquid chromatography. The method is simple, fast, accurate, and, because sample preparation is minimal, it is well suited for use in a teaching laboratory. (JN)

Describes an experiment that: (1) has a derivation step using readily available reagents; (2) requires limited manipulative skills, centering attention on methodology; (3) can be completed within the time constraints of a normal laboratory period; and (4) investigates materials that are easy to acquire and are of great technical/biological…

Discusses polymerization evaluation by spectrophotometric measurements by considering: (1) association degrees and molar absorptivities; (2) association degrees and equilibrium constants; and (3) absorbance and equilibrium constants. (JN)

Describes the absorption and containment (AC) approach to laboratory chemical-spill cleanup. Discusses currently recommended chemical-spill cleanup procedures and evaluates commercially available cleanup materials. Promotes the use of the AC method in terms of its relative safety, availability of materials, and ease of instruction. (TW)
