THE EFFECT OF UTILIZING AUDIOVISUAL MATERIALS IN TEACHING AND LEARNING MATHEMATICS USING SELECTED SCHOOLS IN OSHODI/LSOLO LOCAL GOVERNMENT AREA
The study aimed at examining the effects of mathematics audio and visuals on the learning and teaching of mathematics as well the effects of these audio and visuals on the academic performance of some secondary school students in some selected secondary schools in Isolo Local Government Area of Lagos state.
A well designed and simple questionnaire was distributed to mathematics teachers in these selected schools to accurately evaluate the effect of audio and visuals on the application of learning mathematics in secondary schools in Nigeria.
Concerning the methodology used for the study, the researcher adopted the survey research design with a sample size of twenty (20) teachers and eighty (80) students selected using a stratified sampling technique. Both primary and secondary data were used for the study… (Scroll down for the link to get the Complete Chapter One to Five Project Material)
Background of the Study
The influence of audiovisual materials in promoting student’s academic achievement and teaching and learning in mathematics cannot be overemphasized. The teaching of geometry in Nigerian junior secondary schools needs to be properly handled.
The materials used by teachers to teach and drive home their subject points at the primary and secondary school levels of our education system is incontrovertibly a paramount important issue in practical classroom interaction and successful transfer of knowledge from the teacher to the students. Audiovisual are materials which assist teachers to make their lessons explicit to students.
They are also used to transmit information, ideas, and notes to learners (Ijaduola, 2007). Audiovisual materials include both visuals and audiovisuals such as pictures, flashcards, posters, charts, tape recorders, radio, video, television, computers among others. These materials serve as a supplement to the normal processes of instruction.
Geometry is a subject in mathematics that focuses on the study of shapes, sizes, relative configurations, and spatial properties. Derived from the Greek word meaning “earth measurement,” geometry is one of the oldest sciences.
It was first formally organized by the Greek mathematician Euclid around 300 BC when he arranged 465 geometric propositions into 13 books, titled ‘Elements’. This, however, was not the first-time geometry had been utilized. As a matter of fact, there exists evidence to believe that geometry dates all the way back to 3,000 BC in ancient Mesopotamia, Egypt… (Scroll down for the link to get the Complete Chapter One to Five Project Material)
Statement of the Problem
Previous studies reviewed show that the failure rate in mathematics at junior certificate examinations is high. This could be attributed to a number of factors; one of such factor is the lack or total absence of audiovisual materials. In teaching and learning, audiovisual materials play a key role in concretizing learning.
Audiovisual materials make learning meaningful and help to improve students’ academic achievement. However, these advantages of audiovisual materials have not reflected in the education system because of the dearth of these audio-visual materials in our schools. Hence, the need for alternative audio-visual materials called improvisation… (Scroll down for the link to get the Complete Chapter One to Five Project Material)

- Theoretical framework
- General audio and visuals
- The concept of audio-visual aids
- Types of audio-visual instructional aids
- The importance of audio-visual aids in teaching-learning
- Academic achievement
- Concept of Comprehension
- Concept of Demonstration

Almost every educational reformer has expressed deep concern over the excessive use of words that carry the shadow of meaning but not the substance. Several educationists have struggled to make education realistic. One of such educationist was Dale, E. (1969) who became the chief exponent of audio-visual aids in teaching. He was the originator of the “cone of experience”.
The diagram presented in his book “audiovisual method in teaching.”All the learning experiences can be utilized for classroom teaching. Edger Dale presented all the learning experiences in his pictorial device “pinnacle form” which he called the “cone of experience” if we group the pinnacle from its base; we find that every aid has been arranged in the order of increasing abstractness or decreasing directness.
It may be stated that the “cone” classifies the audio-visual aids according to their effectiveness in communication which means the aids at the base of the cone as “most effective” and relative effect gradually decreases in the cone. Al the pinnacle of the cone, the direct, purposeful, and verbal experiences is represented. The experiences include in the cone were as follows:-
- The direct, purposeful experience that is seen, handled, tasted, felt, touched, and smelt, the experience that is grained through the senses. These experiences are not only direct but are also purposeful. Purposeful means that the experiences are active with a purpose. “An ounce of experience is better than a tone of theory, simply because it is only an experience that any theory has vital and verifiable significance”… (Scroll down for the link to get the Complete Chapter One to Five Project Material)
Audio and visuals are all the objects, things, people and places use to promote the teaching and learning process. The organized combination and utilization of materials facilities equipment and people ease the presentation content for the realization of stated objectives, Ema and Ajayi (2004) state that audio and visuals are all the tools, which can be used by the teacher to provide help and encouragement to learners` learning activities.
In addition, Jocob (1999) stated that audio and visuals are anything and anybody that can be used by the teacher and learners before, during, and after the lesson to facilitate the achievement of objectives. In other words, audio and visuals are devices that facilitate the transmission, understanding, and appreciation of concepts, skills, values, and attitudes… (Scroll down for the link to get the Complete Chapter One to Five Project Material)
- Categories of instruction materials and resources
Audio and visuals are variedly categorized. For instance, Dubey, and Barth, (1980) grouped them into two, namely:
- Reading materials
- Non-reading materials
Michaelis (1980) classified then into
- Reading material
- Audio-visual materials
- Community resources
Another categorization provided by Dubey and Barth (1980) has:
- Reading materials
- Audio-visual material
- Community resources
- Human Resources… (Scroll down for the link to get the Complete Chapter One to Five Project Material)
Concept of Audio-visual aids
Many definitions of audio-visual aids have been made. Most such definitions were made in terms of equipment and materials; and their use in the teaching and learning process. Ofoegbu, (2009) in his illustrations defines audio-visual aids as teaching aids which are of two kinds-materials and verbal. The materials he called the hardware and software used in teaching and these include objects, models, photographs, painting, drawing, diagrams, films among others.
Another definition was made by Talabi, (2004), who sees audio-visual materials as a combination of audio-visual materials which are used in the instructional or learning process to facilitate teaching and learning. According to Abolade, (2004) audio-visual aids are supplementary devices by which teachers, through the utilization of more than one sensory channel is able to clarify, establish, and correlate concepts, interpretations and appreciation.
In his definitions, Nwanna-Nzewunwa, (2003) views audio-visual materials as any device which can be used to make the learning experience more concrete, more realistic, and more dynamic.
Generally, audio-visual materials are those materials which are used by a teacher or an instructor to illustrate the information that is contained in a book in such a way that it will be clearly understood by the students… (Scroll down for the link to get the Complete Chapter One to Five Project Material)
This research work has reviewed some empirical related studies conducted by different researchers and at different times. One such work was that of Chindo, Abdulrasaq, and Ayinla, (2010) who conducted research on the effect of audio-visual audio and visuals on junior secondary schools students’ performance in Ilorin West local government area of Lagos state.
That research work was similar to this research which was based on the effect of the use of audio-visual aids on student’s academic achievement in Mathematics in junior secondary schools in – oshodi government area, Lagos state.
In research design, Chindo used a pretest. Post-test quasi-experimental design was quite similar to the research design for this work. Chindo also employed a sampled population of junior secondary schools (students who were randomly selected for the research work). It is quite similar to the sampled population put in use for this research… (Scroll down for the link to get the Complete Chapter One to Five Project Material)
