Discusses the design and operation of a high Q acoustical resonant chamber which can be used to demonstrate wave phenomena such as three-dimensional normal modes, Q values, densities of states, changes in the speed of sound, Fourier decomposition, damped harmonic oscillations, sound-absorbing properties, and perturbation and scattering problems.…

Students in a methods course on teaching elementary mathematics participated in a mathematics laboratory in a public school. Evaluation indicated that reactions and attitudes were favorable toward the experience. (JP)

Describes experiments that can be carried out by freshmen in general science courses. All experiments are prepared with inexpensive equipment and materials. Quantitative data are analyzed intuitively using graphical representations. (JP)

Describes a circuit which can produce patterns consisting of epicycle curves. The appearance and mathematical nature of some of the patterns is explained. Details are given for the conversion of an oscilloscope to display the patterns demonstrating the practicality of such experiments in most introductory physics laboratories. (JP)

Describes and analyzes an innovative learning program in which first-year graduate social work students were assigned to distinct neighborhoods to use for experientially learning about social welfare, social work, and the consumers of the services. (Editor)

Article discussed computer assisted instruction in the form of TICCIT and the responsibility of the community college in its implementation. (RK)

Describes methods of developing and using cultures of microoganisms suitable for use in elementary school science classes. Emphasis is placed upon the characteristics and culturing of amoeba, paramecia, euglena, rotifers, and algae. (JR)

Describes a grade card system for charting student progress. (SB)
