1.1 Background of the Study
We
live in an age that is experiencing an ever-increasing use of computers in
diverse areas of human endeavor. Computers offer great assistance in
decision-making, operations control, modeling, simulation, automated
manufacturing etc. The history of development shows that so far, no
industrialized nation has been able to make it without the use of computers
(Inyama, 2006).
In
education, computers are used in extremely versatile ways to aid the
understanding of a wide variety of students. Computer science as a feature in
secondary school curricular has been faced with some challenges. Over the
years, students` response to computer science especially in public schools has
been poor and the reason seems to be that
instructional materials specifically audio-visual
materials may not have been used or properly utilized during instruction and
this is a source of worry to the researchers considering its possible effects
on students’ achievement in the subject. This stated problem has often
been attributed to the effects of the use of instructional materials,
specifically, (audio-visuals).
Meaningful learning is most likely to
occur when information is presented in a potentially meaningful way that the
information conveyed is made or presented in a way that the majority of what
was taught remains permanent in the learners memory. Webster’s
Encyclopaedia Unabridged Dictionary of the English Language defines
Audio-Visual Aids as “training or educational materials directed at both the
senses of hearing and the sense of sight, films, recordings, photographs, etc.
used in classroom instructions, library collections or the likes”.
The term has also been defined by Dike, (2011) 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.
