AUDIO-VISUAL AIDS UTILIZATION AND ACADEMIC PERFORMANCE OF STUDENTS’ IN BIOLOGY
Abstract
The purpose of this study was to investigate the use of audio-visual aids utilization and academic performance of students in Biology in Ibiono Ibom Local Government Area. Two research hypotheses were formulated to guide the study.
The study adopted a quasi-experimental research design. The population consisting of all the secondary school’s students in Ibiono Ibom Local Government Area. The simple random sampling technique was used in the study, a maximum of 50 students were randomly selected from each of the four secondary schools that were selected which is made up of two hundred (200) students. The instrument for data collection was Biology Achievement Test (BAT) which consists of ten (10) questions.
The resulting data were analyzed using the independent t-test. It was concluded that one hypothesis was accepted and one was rejected. Based on the findings, recommendations were suggested, which include, governments should install more audio-visual aids in schools and libraries to help in promoting teaching and learning process, all the schools in the state should be linked to national grade to enable them to have electric light notwithstanding the location of the schools.
CHAPTER ONE
INTRODUCTION
1.1 Background to the Study
Audio-visual aids utilization and academic performance of students’ in biology involve the use of recorded pictures and sounds in the classroom. It is one of the instructional strategies or materials which enhances effective teaching and learning of Biology in the secondary schools.
The term has also been defined by Dike (2003), as those materials which do not depend solely upon reading to convey meaning. They may present information through the sense of hearing as in audio resources, sight as in visual resources or through a combination of senses. Indeed the variety of such resources is a striking characteristic. furthermore,
He further grouped Audio-visual aids into Audio resources such as records, tapes, cassettes and radio broadcasts. however, visual resources including models real objects, three-dimensional displays, chalkboard, bulletin board, adhesives graphs diagrams, charts, maps, cartoons, posters and Pictures and projected forms like transparencies, slides, filmstrips, and films.
Audi-visual aids are commonly used to refer to those instructional materials that may be used to convey meaning without complete dependence upon verbal symbols or language Anzaku (2011).
Thus according to the above definition, a textbook or a reference material does not fall within this grouping of instructional materials but an illustration in a book does. audio-visual aids utilization and academic performance of students in Biology.
Some audio-visual components are in the nature of process and experience, for example, dramatizing an event or a procedure, Some Audio-visual materials like motion pictures require the use of equipment to release their latent value. Some do not need equipment at all time an exhibit or a study print.
Anzaku further stated that audio-visual materials include materials and equipment that are considered to be system or body of content potential value when put to work whole equipment or instructions often referred to as hardware component is the means of presenting such content.
Furthermore, according to Edem Ntuk (2010). Instructional materials are human and nonhuman resources which may be used by the learners in isolation or combination formally or informally to facilitate the acquisition and evaluation of knowledge, skill and moral. In conclusion, he added that an effective teacher can use the following materials for effective teaching:
AUDIO-VISUAL AIDS UTILIZATION AND ACADEMIC PERFORMANCE OF STUDENTS’ IN BIOLOGY
1. Projected materials
2. None projected material
Projected visual require the use of optical or electronic devices to project images (still or opaque) on the screen for viewing. As a result, these require projections, skill equipment, materials, and electricity. Non-projected visuals do not require any of these specified conditions before they can be presented or utilized for instructional purposes. Example of projected materials is Audio-cassettes, disc (CDs), radio broadcast, record players, videocassette, TV broadcast, cinema, etc while not projected materials are graphics, model, photographs charts, posters, etc.
In laboratory science, the use of audio-visual technology is particularly useful, as it enables the visualization of procedures and allows for deeper comprehension that obtained just through texture presentation Okworo (2008). In conclusion, instruction of audio-visual materials in both laboratory and secondary schools by government and effective utilization by teachers will minimize the statement that science students in secondary schools are poor in performance.
1.2 Statement of the Problem
The study is motivated by the fact that students do not retain for long or understand what they are taught without audio-visual aids. Such learning does not encourage participation and lacks interest or stimulation. It is not based on sense experience nor does it extend their experience. Above all, such learning cannot be permanent. Yet, there is also evidence of low utilization and nonavailability of audio-visual aids in schools. The study will, therefore, investigate the audio-visual aids utilization and academic performance of students in Biology schools so that note will be taken of the hindrances and work towards promoting the used of audio-visual instructional materials (Aids).
1.3 Purpose of the Study
Therefore, the purpose of the study was to investigate the influence of audio-visual aids utilization and academic performance of students in Biology in secondary schools in Ibiono Ibom Local Government Area.
1.4 Significance of the Study
Audio-visual aids have been in existence for a long time, but they are often underutilized. it is expected that, following the identification of the hindrances to maximum performances of science students, the study will be of benefit to students, teachers and the society at large.
Hance, discoveries from the study will guide teachers, government, sponsoring bodies and donors on the purchase of not only printed materials (textbook) but also non-printed materials (Audio–visual) for schools for effective teaching and learning.

1.5 Research Hypotheses
The following research hypotheses were formulated to guide the study:
i. There is no significant difference in the mean performance scores of students exposed to audio-visual aids and those not exposed to.
ii. There is no significant difference in the mean performance scores of male students exposed to the use of audio-visual aids and female students who are exposed to the use of audio-visual aids.
1.6 Limitation of the Study
The limitation experienced in the course of the study was the time given for the completion of the study the time was an inadequate, and financial constraint which was very hard for the researcher to expand the scope of the study.
1.7 Delimitation of the Study
The study was concentrated on audiovisual aid utilization and academic performance of students in a secondary school in Biology in Ibiono Ibom Local Government Area.
1.8 Definition of Terms
The following terms were used in for study:
Audio: This is connected with hearing and recorded sounds.
Visual: This is connected with seeing or sight.
Audio-visual: It involves using both sight and sound, typically in the form of images and recorded speech or music.
Aid: Aids is an instrument that assists the teacher in the effective communication of teaching and learning in the classroom.
Academic Performance: Is the outcome of education, the extent to which a student, teacher or institution has achieved their educational goals.
Biology: Is the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy behaviour, origin, and distribution.
