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…

Demonstrations that can be used to lead students to wonder and write about basic scientific principles are presented. Each demonstration includes the concept demonstrated, a list of materials, and procedures. Concepts include density and temperature of liquids, contracting matter with heat, atmospheric pressure, dramatic color changes, fireproof…

Describes a simulation of chemical reactions to help students understand factors that affect the rates of chemical reactions. (PR)

Identified are potential dichotomies that must be confronted by the would-be popularizer of science--science and technology, the applications and misapplications of science, simplification and complication, certainty and speculation. The importance of writing scientifically is urged. (KR)

The demonstrations presented in this article relate to everyday life, address interdisciplinary aspects, and have implications for the life sciences. Topics of the demonstrations are electricity calculations, astronomy, electrolysis of water, ester synthesis from butyric acid and pentanol, catalysis, and minerals. (PR)

Describes activities to help students understand pH scales and acid rain. (PR)

Describes a three-week environmental minicourse in a general chemistry class. The minicourse consisted of two distinct phases, a one-week introduction to environmental chemistry and a two-week project involving a particular environmental problem. (PR)
