How can audio-visual aids be used to advantage in the teaching of plane geometry

Abstract

Scope of Study: Audio-visual materials have long been accepted as a valuable teaching aid in many subject areas. Teachers of plane geometry, however, have not made proper use of the potential that lay in this medium. This report attempts to present the audio-visual methods and techniques that are available to the teacher. It stresses the practicality and usefulness of the various types of audio-visual materials. The opaque projector, the felt board, models, motion pictures and filmstrips are discussed. There are suggested uses of the opaque projector; several felt board demonstrations are included; the construction and uses of several models are discussed. The correct steps in showing a film or filmstrip are given in detail. There is also included a list of thirty-six motion pictures and filmstrips that are available for the use of the teacher. It gives the title, length, producer or distributor, and a resume of each film and filmstrip. Materials used in this report are chiefly from recent periodicals and texts in the field of audio-visual materials.

Finding and Conclusions: There are many excellent methods and techniques available for the teacher of plane geometry. The ease of presentation, adaptability, and financial cost of the filmstrip probably make it the most practical and useful -of all the audiovisual materials. The opaque projector is a very versatile piece of equipment and can be used to great advantage in the classroom, particularly in showing teacher-made materials. The motion picture can best be used as an aid in teaching units where motion is inherent for pupil understanding. Films may also be used to stimulate pupil interest. Models are most useful in motivating thinking. A model on a display, available for pupil investigation will do much to clarify the meaning of the theorem it portrays.
