The aim of this guide is to aid elementary teachers in individualizing instruction. Eight general objectives of teaching mathematics are listed, 11 topics are identified as being the scope of elementary mathematics, a one-page mathematics curriculum flow chart for grades K-8 is provided, student and teacher needs and evaluation are discussed in…

Describes a chemical engineering laboratory course based on the modelling and computer simulation of dynamic experimental conditions. (MLH)

Discusses the advantages of using color slides and accompanying objective questions to evaluate engineering laboratory students. (MLH)

Describes a procedure which utilizes a laser beam and an interferometer to determine the stability of a holography system. Equipment set-up, operation, and interpretation of results provided. (CP)

A guided/open-ended format for general chemistry laboratories is used at the University of Oklahoma. This format is much more reflective of the scientific enquiry processes than the traditional verification format, and it allows students to investigate chemistry at a level consistent with their level of intellectual development. (BB)

An apparatus is described for storing laboratory glassware in freshman organic chemistry laboratories. The glassware is mounted on pegboard using hardware gripper clips, and the pegboard is fitted in a slot down one side of the storage cupboard. (BB)

Presents a simulation model approach to the study of evolution. This model combines both practical and theoretical aspects of evolutionary biology course work. The author has used laboratory hardware for this simulation with 20 working groups of students. (HM)

Described is the construction and use of an environmental garden. The garden serves as a source of both indoor and outdoor laboratory materials, including vascular plants, fungi, algae, mosses, zooplankton, and macroscopic invertebrates. (BB)

This experiment uses the effect of the relativistic mass increase of electrons on the results of x-ray photoelectron spectrometry to obtain the rest energy of electrons. (BB)

This symposium centered on the choice of content in chemistry courses. (BB)

A chemical demonstration book project was described. (BB)

Presented here are improvements in the original design of an introductory statistical thermodynamics experiment with the result that heat capacities of metals are routinely obtained within ten percent of literature values. (BB)

In this paper an experiment is described in which the equilibrium constants necessary for determining the composition and distribution of lead (II)-oxalate species may be measured by linear sweep voltammetry. (Author/BB)

This experiment develops the students' ability to carry out a simple recrystallization effectively, and demonstrates how a solvent may be selected or rejected for the recrystallization of a specific organic compound. (Author/BB)
