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 schools
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 was 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
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 have electric
light notwithstanding the location of the schools.
CHAPTER ONE
INTRODUCTION
1.1 Background to the Study
Audio-visual Aids involves 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. He grouped
Audio-visual aids into: Audio resources such as records, tapes, cassettes and
radio broadcasts. Visuals resources including models real objects, three
dimensional displays, chalkboard, bulletin board, adhesives graphs diagrams,
charts, maps, cartons, 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.
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 picture 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 are the means of
presenting such content.
According to Edem Ntuk (2010). Instructional
materials are human and non human 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. He added that an
effective teacher can use the following materials for effective teaching:
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, video cassette. TV broadcast, cinema etc while non 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 minimized 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 in sense experience nor does it extend
their experience. Above all, such learning cannot be permanent. Yet, there is
also evidence of low utilization and non availability of audio-visual aids in
schools. The study will therefore investigate the audio-visual aids utilization
and academic performance of students in secondary 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
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. 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.
