Investigates the effectiveness of guided inquiry laboratories for the first semester general chemistry course for science majors at the University of Oklahoma, Norman, Oklahoma. The focus is on three skills: data interpretation, hypothesis formation and the experimental testing of hypotheses. (HM)

In this experiment, the observation that, for meta- and para-substituted styrene derivatives, the magnitude of the C-13 shielding value for the beta-carbon is linearly related to sigma for the ring substituent is used to determine sigma. (BB)

In one option for this project, the rotation-vibration infrared spectra of a number of gaseous diatomic molecules were recorded, from which the fundamental vibrational wavenumber, the force constant, the rotation-vibration interaction constant, the equilibrium rotational constant, and the equilibrium internuclear distance were determined.…

Explains a laboratory exercise where 2-methylpyrazinepentacyanoiron (II) is synthesized by thermal and photochemical pathways. (GA)

A framework of selected administrative guidelines is presented for language laboratory directors and supervisors. Internal administration and operation, relations with faculty, and roles outside the university are covered. (SW)

Describes three simple experiments using Fermat's principle; a single reflection, Schwarz's triangle problem, and light triangle inscribed inside a circle. (GA)

The demonstrations and experiments described in this article are appropriate for junior high school and older students, including beginning students in college biology or botany. Included are culture and observation of zoospores, zoospore attraction to plant roots, and other topics. (BB)

Presents the following chemistry lecture demonstrations and experiments: (1) a versatile kinetic demonstration; (2) the Bakelite Demonstration; (3) applying Beer's law; and (4) entropy calculations. (HM)

Presents a formulations laboratory project in which secondary school students attempt to prepare a common household product from laboratory chemicals. (HM)

Presents two experiments concerned with mapping skills. Directions are given for calculating the circumference of the earth and for developing a model of the solar system using familiar territory as a frame of reference. (MA)

Traces physics curriculum innovation in Southeast Asia since the 1950s. The unique features of such innovation in Indonesia, Malaysia, Philippines, Singapore, and Thailand are highlighted. Forecasts for the future of physics education in part of the world are also discussed. (Author/HM)

Reviews several previously published uses of disposable plastic syringes and presents ten new uses in several different areas of physical science. (Author/GA)

Video cassette demonstrations are useful in teaching experimental techniques and instrumentation. This article describes how the recorded demonstrations save instructor and student time, how they can be integrated into a multimedia teaching format, and how recordings support student independence. (Author/BB)

The National Network for Curriculum Coordination in Vocational-Technical Education has become a significant national medium for exchange of vocational curriculum information and materials, the authors state in reviewing the network's organization and accomplishments. However, funding arrangements have created friction within the networks. (MF)

The use of basic oceanography equipment in junior high and senior high school science applications is described. (CP)
