By converting functional equations to cylindrical coordinates, plotting points on cardboard, and connecting these points with thread, one can make three-dimensional string figures illustrating the behavior of functions for which the derivative is not always defined. (SD)

A discussion of how to visually interpret a piece of music. (HB)

Describes the use of 35 mm slides consisting of a diagram of photograph and 15 to 60 words of text to augment laboratory instruction. (GS)

The purpose of this study is to explore the potential uses of photography and its practical implications as a qualitative evaluation technique. Potential uses are proposed: (1) systematic recording of a program activity; (2) highlighting specific events; (3) illustrating a point; (4) leading the evaluator to specific persons, activities, and…

Visual knowledge is an enormously important part of our total knowledge. The psychological study of learning and knowledge has focused almost exclusively on verbal materials. Today, the advance of technology is making the use of visual communication increasingly feasible and popular. However, this enthusiasm involves the illusion that visual…

The past decade has seen a substantial growth in methods and schemes for the display of multivariate data. This paper encompasses a sketch of the history of multivariate displays, from the pre-Columbian Quipu to Chernoff's Face; examines a number of techniques; describes their construction; illustrates their use; and comments on their efficacy.…

In order to investigate the relative effectiveness of specific media attributes on student performance on criterion tests, a comparison was made of the effectiveness of two levels of stimulus explicitness in visuals in facilitating student achievement on criterion tests of knowledge, comprehension, and total understanding. Subjects were 171…

Examines reasons for the declining use of cassette film loops in British classrooms in recent years. (JR)

A method largely utilizing pictures and charts is proposed, whereby the learning and manipulation of French verbs would be facilitated. (Text is in French.) (TL)

Since continuing education students have their own set of characteristics, visual presentations used to instruct them should be reexamined. Six suggestions for improving the content, impact, and effectiveness of teacher-prepared slide presentations are offered. (AG)

This paper considers the case of two predictor variables. Figures are obtained which show the regions of significance of joint regression coefficients, regression coefficients considered separately, and the multiple correlation. The intersection of these regions of significance and non-significance illustrates how the various apparent…

The paper suggests ways in which the teacher of English as a second language may use slides to stimulate students by teaching through, and not just about, the slides. Slides are useful when used as a tool to uncover the students' creative and imaginative faculties, which may fail to be discovered through conventional language teaching. The use of…
