Describes an experiment, easily repeated in the classroom, designed to determine whether members of the species Drosophila melanogaster show selective preference in choice of mates. (PEB)

Presented is a discussion focusing on teaching radioactivity in the schools. The author suggests equipment available and experiments that can be performed. (PEB)

A number of activities are described by which a class can collect biological data about the students in the class. Brief instructions are given. (RH)

This article reviews the conceptualization, measurement, and design of brief experimental analysis for oral reading fluency problems. It presents examples from the literature of how brief experimental analysis results have been used to generate effective treatments for a variety of different applications (e.g., parent tutoring, small group,…

Author focused on the basic principles that should inform educational theory and methodology. (Author/RK)

This second report from the Analytical Chemistry Subcommittee presents ideas for using real-life samples for student analysis and for introducing the topic of developing procedures for analysis. (DT)

The National Science Foundation has awarded four companies over a million dollars to carry out solar energy space-heating experiments at different schools in Massachusetts, Minnesota, Maryland, and Virginia. (MLF)

Describes an experiment designed to familiarize students with the operation of a precision spectrophotometer, the effects of changes in operating variables, and the characteristics of such components as sources and detectors. (SLH)

Describes four experiments designed to introduce students to the methodology associated with the construction, evaluation, and use of ion-selective electrodes. (SLH)

Describes a method for the accurate determination of partial specific volume of a protein. Method is simple enough to include in the undergraduate physical chemistry laboratory but requires patience and careful handling which provide good training in laboratory techniques. (SLH)

Describes an interesting, inexpensive, and highly motivating experiment to study uniform and accelerated motion by measuring the position of a car as it crashes into a rigid wall. Data are obtained from a sequence of pictures made by a high speed camera. (Author/SLH)

A required course for graduate teaching assistants on improving the quality of instruction in the undergraduate laboratories is described. As a principal feature of the course, the graduate students improved existing laboratory experiments or developed new ones. Both self-evaluation and evaluation by faculty members were applied to the final…

The purpose of this research was to determine if students taking the experimental course, Crises in Human Relations, showed significant reductions in dogmatism and if changes occurred, how these changes compared to those found for other students exposed to specified University experiences and for control groups.
