Audio-Visual Materials Utilization And Academic Performance Of Students

CHAPTER ONE – INTRODUCTION

 1.1       Background of the Study

The global wave in the use of educational technology and its revolutionary effects is a major attraction to the choice of this topic for study. This project examined systematically the effects of the use of students in developing nation like Nigeria taking the case of a private primary and secondary school library. The choices of schools have no functional libraries. There is a growing consciousness among some private school libraries.

This project identified a whole wide range of audio-visual materials and their equipment for operation abounds in the library. However, many a time materials and equipment are not used in the library. Similarly, the students are unable to use the materials and equipment themselves. There is no convenient time for them to use the audio-visual materials and equipment.

Despite all these constraints, audio-visual technology is adequately used in the school in technology and learning. The results gathered indicated that student’s academic performances are significantly improved after being taught using audio-visual technology.

Nowadays, knowledge is recorded in many physical forms. Before printing was invented, the papyrus vellum, codex etc were used in recording human knowledge. With the invention of printing come books and other printing forms. Recently, another form of media has come into prominence and that is the audio-visual media. Audio-visual may include graphic materials such as pictures, map chart, sides etc and family multimedia package such as motion pictures, video recording etc. There are also information-bearing items like microforms, computer-readable data files and three – dimensional objects e.g botanical specimens.

Audio-visuals have a variety of definitions. It is derived from a Latin word meaning “I hear” in a library and information science, it is a replay of sound which uses hear. This covers microforms, disc recorder amplifiers, loud-speakers, and their enclosures and any other techniques which are used to record or replay sound waves (Sincher, 1977) cited in (Robsoni, 2005).

Audio-visuals mean something related to sound and visual or light. They include printed materials and their equipment. Audio-visual material can be categorized into audio materials and visual materials. Audio includes Radio, Lecture/talk, Audio tape/cats cassette, Compact Disc, Telephone, etc. The visual material can be identified by grouping them into two ways 2 dimensional and 3-dimensional projectiles and non-projectiles. Visual materials can also be classified under graphics/photographic.

Audio-visuals are a combination of audio media packages, VCR, and even computer programmes. Some cannot be treated without the equipment for using them as projectors, TV, receiver, Microreader Record player, photocopying machine, VTR Laminating 35mm camera with accessories etc. They can also exist in some other forms as slides of computer screens, down leading of computer search, interactive video disc which requires the image storage medium, a TV monitor or receiving inputs. They are usually not in the book and so are not easily available. Also, usually expensive because some of them require projectors; Moreso, they are usually hard to process because they lack some of the normal bibliographic detail. They, however, can be cataloged using the territorial areas. Finally, they are of easily accessible to the user. They are used mainly as reference materials and user are encouraged to borrow them
