Describes an apparatus which attempts to give a direct visual impression of the random detection of individual photons coupled with the recognition of the classical intensity distribution as a result of fairly high proton statistics. (Author/GA)

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)

Presents several new products and equipment for teaching college science courses such as laser optics bench, portable digital thermometer, solar energy furnaces and blackboard optics kit. A description of all equipment or products, cost, and addresses of manufacturers are also included. (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)

Describes an experiment to demonstrate the influence of a magnetic field on the behavior of a single Langmuir probe. The experiment introduces the student to magnetically supported plasma and particle behavior in a magnetic field. (GA)

Investigates the reasons for students' failure in an introductory volumetric analysis course by analyzing test papers and judging them against a hypothetical ideal method of grading laboratory techniques. (GA)

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)

Three experimental kindergarten curriculum enrichment approaches were tested in relation to their effect on reading readiness with a total of 106 children. (DLS)

A computation learning lab was planned, implemented, and evaluated as a way of helping learners conquer computation problems. Features include: emphasis on a premotivation activity; the use, on a regular basis, of eight instructional strategies; and active parent support. The lab students showed dramatic gains. (MP)

This informal report describes uses of single-user, personalized computer systems at the University of Michigan and discusses the implications of new technologies for improving access to higher education. (Author/MP)
