Presents two hydroboration-alkylation sequences, each requiring a three-hour laboratory period, that demonstrate the synthetic utility of the organoboranes. (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)

Describes the quantitative analysis of a gaseous mixture using peak heights and ratios between the peak heights. (MLH)

Some of the problems associated with setting up a computer simulation are examined. Uses of computer simulation as a teaching tool in the life sciences are detailed with some examples presented from courses at Sturt College of Advanced Education. (BT)

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

Described is an introductory life science course which introduces students to questions relating social values and science. Suggested lecture, laboratory, and discussion exercises are included. (SL)

Described is a physics experiment in which carbon dioxide cartridges mounted on a wheel with a spark timer can be utilized to measure the energy release of the cartridges. (SL)

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)

Examines some of the objections of secondary school teachers to the application of the Personalized System of Instruction (PSI) or Keller Plan and provides reasons why these objections are not valid. (PEB)

Describes the design, construction, and performance of a low-cost, transversely excited molecular nitrogen laser. Suggests simple experiments and demonstrations using this laser. (MLH)

The purpose of this study was to explore and discover classroom management problems encountered by undergraduate science teaching assistants (TAs). Information about TA perceptions of classroom management problems was obtained to better understand how gender, teaching experience, and academic discipline affected their classroom management…

This National Science Foundation (NSF) report, prepared by NSF's Division of Undergraduate Education (DUE), analyzes the role the Foundation plays in recognizing and supporting the critical function of community colleges in science, mathematics, engineering, and technology (SMET) education. The Foundation aims to improve and strengthen SMET…

This chemistry textbook presents a beginning course for schools or colleges. It presents a more complete classification than usual according to chemical analogies, the explanation of chemical phenomena in ordinary language, as well as symbols, and the addition of a complete set of formulae in the appendix. A number of recent and important…
