Effects of Audio-Visual Compact Disc Instructional Package on Performance of Junior Secondary School Students in Igbo Vowels and Consonants in Minna Metropolis, Niger State.

Abstract

The study investigated the effects of audio-visual compact disc instructional packages on achievement of junior secondary school students in Igbo vowels and consonants in Minna Metropolis, Niger State. It examined the significant difference in the test achievement scores of students taught using audio-visual compact disc and lecture method. Two research questions were raised and two null hypotheses were tested at 0.05 alpha level. Sixty (60) junior secondary school students were drawn from two junior secondary schools within Minna metropolis as sample for this study. The population for the study comprises all secondary school students in Minna metropolis. The research design adopted was pretest posttest experimental control group design. The experimental group were taught using audio compact disc package while control group was treated using conventional lecture method. A 20-item Vowel-Consonant Achievement Test (VCAT) was developed and was validated. Its reliability was found to be 0.88. The two hypotheses of this study were tested using t-test statistic. The findings of the study showed that students taught Igbo vowels and consonants using audio compact disc package performed better than those taught using conventional lecture method. Male, and female students did not differ significantly when both were taught using audio disc instructional package. Based on the above findings, it was recommended that audio-visual disc instructional package should be used by all language teachers especially those Igbo language teachers in secondary schools.
