Types of Visual Aids and Their Uses 89
Please do not misunderstand me, I am not criticizing the motion picture as a visual aid. I think the motion picture is possibly the most valuable teaching aid that we have, when it is used for the purpose for which it was made, that is, to show motion. On the other hand, the still picture is a valuable teaching aid when it is used as intended."
The filmslide is unusually economical to purchase. A complete roll of twenty-five to seventy-five pictures may be purchased at an average cost of two to five cents per picture. A roll of filmslides weighs about one ounce, and is kept in a box or can so small that several will fit into the palm of one's hand. Also, the fact that the pictures are arranged in a carefully edited sequence on the strip of film appeals to many teachers of standard subjects in the curriculum; they do not always have the time or inclination to assemble individual slides from various sections of a cabinet and redistribute them properly after use. The projection equipment for use with filmslides is inexpensive, simple to operate, and economical in weight and space.
There are many teachers who desire to prepare illustrative materials for projection in their classes. In most cases, these teachers have but limited funds with which to cover the cost of such materials. The filmslide offers the least expensive photographic slide service. As explained later, small cameras are available to be used in taking pictures on 35 mm. negative. These cameras are simple to operate and are efficient. The pictures are just the right size to be used in the filmslide projector, and may be produced easily at home, in school, or in the camera club. Thus, by the exercise of a little care and skill, excellent filmslides can be made by a teacher who has access to a 35 mm. miniature camera. The entire cost of materials, developing, printing, etc., may be kept below an average of five cents per picture, ready for projection.
Many school administrators and supervisors, as well as instructors, have found such photographic apparatus to be very convenient for recording special teaching projects, situations where repairs and replacements are needed, photographs qf pupils, and the like. At the appropriate time, these may be projected for group discussion and consideration. Teachers of vocational agriculture may photograph livestock and growing crops during the summer months when school is not in session, and use these pictures during the winter for class study. Some prepare photographs of special drawings and charts for projection before classes.
