Presented is a photoelectric colorimeter which can be assembled by the student. Reports that it can do many of the same analyses as the SPEC 20 but at a greatly reduced cost using older technology. Presents several experiments to use with the colorimeter. (MVL)

Discusses a method for teaching time pulsed NMR principals that are as simple and pictorial as possible. Uses xyz coordinate figures and presents theoretical explanations using a Fourier transformation spectrum. Assumes no previous knowledge of quantum mechanics for students. Usable for undergraduates. (MVL)

Describes the use of "CACHE IBM PC Lessons for Courses Other than Design and Control" as open-ended design oriented problems. Presents graphics from some of the software and discusses high-resolution graphics workstations. Concludes that computing tools are in line with design and control practice in chemical engineering. (MVL)

Evaluates and compares common eyewash stations currently being used in laboratories. Discusses types available, installation, water supply needs, and maintenance. Lists current OSHA eyewash station standards. (ML)

Follows the development of a course in nuclear and radiochemistry at Penn State. Lists specific nuclear science topics covered in the undergraduate level course. Describes audio-visual materials that have been developed for the course and includes a survey of students taking the course. (ML)

Describes a simple laboratory procedure for changing sodium carbonate into sodium chloride by adding concentrated HCl to cause the reaction and then evaporating the water. Claims a good stoichiometric yield can be obtained in one three-hour lab period. Suggests using fume hood for the reaction. (ML)

Recommends using iodide ions and peroxodisulfate ions for studying rate laws instead of the standard iodine clock for kinetic study. Presents the methodology and a discussion of the kinetics involved for a laboratory experiment for a high school or introductory college course. (ML)

Describes a biophysical chemistry experiment that introduces students to globular protein conformation and microcomputer analysis of initial rate data for the unfolding of proteins. Presents background, materials needed and methodology. Uses a visible spectrometer for analysis. Lists educational benefits derived from the experiment. (ML)

From an analysis of 14 secondary student's actions and thought processes, it was found that technology's level of information affected the focus of student observations. The microcomputer group focused primarily on the graph while other groups exhibited multiple foci. The discussion data also reveal that students have three main ideas about how…

A high school teacher examined how using technology in his chemistry classroom would affect students' attitudes and motivation. Observations, interviews, and surveys indicated that students stayed on task longer, wanted to come in to finish labs, wanted to know how they could improve, and felt they understood certain concepts better. (SM)

A teacher shares three instructional aids that she used to teach blind as well as sighted students the basic principles of chemical bonding.(ZWH)

Describes activities that can be added to any chemistry curriculum and can offer students an opportunity to gain and practice skills in research, written and verbal communication, and database creation and use while working as a part of a problem-solving team. (JRH)

Results involving 701 female and 933 male advanced science students in the United States from the Second International Science Study are discussed. Focus was on differences between females and males. Gender differences were found, particularly in opinions regarding science and society, and with respect to general questions about school. (TJH)

Presents results of intensive clinical interviews with 11 high school chemistry students representing a broad range of achievement levels as selected from 180 students who completed a written test upon completion of an instructional unit on chemical change. Results indicate that students commonly experience difficulties in chemical knowledge,…

A symposium that focused on the education of chemistry teachers in China at predominately the middle and high school levels is discussed. The topics of curriculum and textbook reforms, instructional uses of modern technology, science-technology-society, collaborative efforts with educational psychologists, hands-on laboratory work, and the…
