Presents author's view of how computer graphics produced in the classroom enhance mathematical concepts teaching. Specific concepts and related graphics presented include the convergence of power series and the Central Limit Theorem. Formal versus informal instruction, computer assisted instruction versus teaching, and requirements for future…

Because class size often limits student opportunity to handle individual models, teachers use stereoscopic projections to demonstrate structural features. Describes three-dimensional pointers for use with different projection systems so teachers can indicate a particular atom or bond to entire classes, avoiding the perspective problems inherent in…

Described is a visual aids facility created to enhance college classroom work in land use, planning, urban administration, local government, and real estate. The facility has two major features: mounted aerial photographs and a visual aids display case that houses a transparent overlay system. (RM)

A sanitarian uses a model to demonstrate installation and operation of a subsurface disposal system. The model contains a septic tank, inlet and outlet T's, distribution box, and drain lines in various stages of construction. The model is used to inform mobile home owners about environmental health practices. (MR)

Describes the use of various indicators to demonstrate chemical reactions; the display of sodium as a shiny metal; and the illustration of the attainment of chemical equilibrium with beakers of chemicals and an overhead projector. (MLH)

In response to online discussions regarding whether communication educators should teach students in public speaking how to utilize Microsoft PowerPoint for developing visual aids, this paper identifies arguments both for and against the practice. The paper begins by delineating the three relevant questions and describes the positions offered by…

The overhead projector is shown to be a superior alternative to the chalkboard. Uses and advantages include these: planned visual instruction with key ideas featured in color, face-to-face instruction with lights on or off, progressive revelation or serialized transparencies, and clarity of information presentation.
