A number of possible self-experiments in nutrition are listed. (JR)

Discusses the use of two television sets with UHF coverage and a window screen or aluminum foil reflector to conduct a take-home experiment in physics. (CC)

Discusses the philosophy and operation of a self-instructional laboratory at MIT which utilizes visual materials reinforced by audio tapes and is designed to give the student a taste of how to collect, display, and interpret data. Indicates that the approach results in the flexibility needed to serve self-paced courses. (CC)

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.…

Discusses the controversy about the discovery of element 72, involving Urbain's isolation of celtium, Dauvillier's reexamination of celtium samples, and Coster and Hevesy's announcement of the existence of hafnium. Indicates that the Copenhagen workers are finally accredited for the element discovery in their x-ray spectral studies. (CC)

Study was concerned only with the impact of tutoring on the tutor's learning and attempted to determine whether tutors cognitively restructure the material in anticipation of teaching it to someone else. (Author/RK)
