AUDIO-VISUAL INSTRUCTION AND LEARNING OUTCOMES INPHONETICS: EVIDENCE FROM SENIOR SECONDARY SCHOOLS INKADUNA STATE

Abstract

This study investigated the effects of audio-visual instruction on students’ learning outcomes in phonetics among
Senior Secondary School students in Kaduna State, Nigeria. A quasi-experimental pre-test and post-test control
group design was employed. The sample comprised 120 students drawn from two public secondary schools in
Giwa and Zaria Educational Zones out of a population of 21,600 students. Data were collected using the Phonetics
Performance and Retention Test (PPRT), with a reliability coefficient of 0.82. Descriptive statistics and t-tests
were used for data analysis at the 0.05 level of significance. The findings revealed that students exposed to audiovisual instruction performed significantly better than those taught using conventional methods. The study
concludes that audio-visual instruction enhances students’ understanding of phonetic concepts and improves
academic performance. It recommends the integration of multimedia instructional strategies into phonetics
teaching in secondary schools.
