The author, in this new edition of a 1945 classic on film theory, proposes that films have a greater influence on the minds of the general public than any other art form; therefore, a careful study of film is necessary to control and direct its potential influence. He delineates the early history of films, pointing out that not until 10 or 12…

The relative educational effectiveness of color vs. black and white television has not been exhaustively explored. While previous studies have concentrated on the factual retention of subject matter--bypassing the subjective attitudes--this study was designed to thoroughly analyze both areas. Using Osgood's Semantic Differential and the Liking…

Classroom environmental factors that promote or inhibit a climate facilitating learning are discussed, and general principles that may serve as a guide to developing effective classroom settings are presented. (MJB)

Presents the options and limitations available in microcomputer-based graphic systems. Factors that must be considered when selecting a system--resolution, color, video-compatibility, and cost--and the relationship between these factors are discussed. (MBR)

Reports on the colors observed during titrations of 15 natural indicators obtained from common fruits and vegetables. These edible indicators can be used for a variety of teacher demonstrations or for simple student experiments. (JN)

A simple device used to demonstrate the main features of primary color addition is described. Materials needed to construct the device, procedures used, and typical results are discussed. (JN)

Examines the physical basis for colors of noble metals (copper, silver, gold) developed from energy conservation/quantum mechanical view of free electron photoabsorption. Describes production of absorption edges produced by change in density of occupied valence electron states in the d-band, which allows stronger absorption in the visible photon…

The Visual Communication section of the Proceedings contains the following seven papers: "Teaching the Use of Color: A Survey of Visual Communication Division Members" (Lyle D. Olson and Roxanne Lucchesi); "The Development of Self- Efficacy in Young Women in Relation to the Perception of Attention to Sexuality as Power in…

In this activity, students test whether the color of a material affects how much heat it absorbs. An ice cube is placed in a box made of colored paper (one box per color; white, yellow, red, and black) which is then placed in the sun. Students predict which color will melt the ice cube first and record the order and time required for the ice cubes…

Most people certainly take light for granted. But understanding the basic nature of light can open up a whole new world! All about Light takes kids on a fun journey to answer questions like: "Why does light shine through some things and not others?" and "Why can we see our reflections in water, but not in a rock?" Students learn how light travels…

Why does light behave the way it does? How does it travel from its source to the objects it illuminates and then to human eyes? Students will learn about waves, including the concepts of reflection, absorption, refraction and how light is related to the colors that can be seen. With a hands-on activity and real-life examples, these concepts are…

Experiment was designed to examine the relationship between intelligence, stimulus meaningfulness and stimulus selection. (Authors)

Discusses a comparative study of three approaches used to minimize reading difficulties: words in color, the initial teaching alphabet, and the Lippincott Basic Reading Program. (SW)

Describes an experiment enabling students to apply concept of diffraction, determine limits of their color perception, learn how to measure wavelength with a simple apparatus, observe continuous and line spectra, and associate colors with corresponding wavelengths. The homemade diffraction-grating spectrometer used is easily constructed. (JN)
