Summarizes 12 papers presented at the Fourth Biennial Conference on Chemical Education that dealt with suggested modifications in the ideas and terminology taught in a variety of chemistry courses. (MLH)

Describes the use of various indicators to demonstrate chemical reactions; the display of sodium as a shiny metal; and the illustration of the attainment of chemical equilibrium with beakers of chemicals and an overhead projector. (MLH)

Describes a pilot study in which a two-year junior college program designed to train chemical technicians was taught to a group of high school students. The concrete-operational program, entitled Modern Chemical Technology (MCT), was well received by the students. (MLH)

Describes a computerized experiment in which the student determines the pk of an acid-base indicator from absorption spectra of the indicator at various concentrations. (MLH)

Students perception of the social learning environment in secondary school science courses were examined. The different environments that were perceived within the individual science courses and results, examined in light of student interest in science, are discussed. (BT)

Presents laser demonstrations of the surface photoelectric effect and the measurement of the laser beam wavelength; recommended for teaching the relationship between light energy and wavelength. (MLH)

Describes 20 chemical demonstrations designed for elementary school science classes. These can be presented as a magic show, but each illustrates one or more of seven basic chemical concepts. (MLH)

Describes a biochemistry experiment that illustrates the methodology of affinity chromatography by attaching avidin, a glycoprotein in egg white, to a Sepharose matrix in order to bind biotin-containing proteins. (MLH)

Discusses research on the structures of metalloproteins and the role of iron in biological transport systems. (MLH)

Describes a card game that uses chemical symbol and number cards to represent chemical formulas. Also discusses an end-of-term review game that utilizes competing teams. (MLH)

Discusses the special aspects of chemical higher education programs in Africa, the influence of government in African universities, and university research programs and facilities. (MLH)

What criteria should be used to include or exclude particular topics within a country's science curriculum? It will be argued here that gold/gold mining is a suitable and relevant topic for inclusion in PNG's science curricula and suggestions towards achieving that end will be offered. The teaching of the mining of copper ore and the metal's…

There is evidence to suggest that first-year chemistry learning experiences may discourage students from studying further chemistry courses. This paper reports on an investigation on the influence of first year learning experiences in two first year chemistry courses on students' chemistry enrollment choices. Students enrolled in first year…

This book, part of The Exploratorium science "snackbook" series, explains science with a hands-on approach. Activities include: (1) "3-D Shadow"; (2) "Bits and Bytes"; (3) "Circuit Workbench"; (4) "Diamagnetic Repulsion"; (5) "Film Can Racer"; (6) "Fractal Patterns"; (7) "Hoop Nightmares"; (8) "Hydraulic Arm"; (9) "Hyperbolic Slot"; (10) "Light…

Proceedings from the first three History and Philosophy of Science and Science Teaching Conferences are examined to identify the profile of papers in science content areas. Those papers with a chemistry education emphasis are investigated more closely. Results indicate that papers with physics content dominate. Chemistry and biology content were…
