This study investigated the effects of audio- visual materials on the performance of students in oral English in Ekiti State, Nigeria. The study adopted the quasi-experimental, pretest, posttest control design. The design included an experimental and one control group. The population for the study consisted of all junior secondary school two (JSS2) students in public secondary schools in Ekiti State; while the sample for the study were120 students. The students were drawn from six classes purposively selected from co-educational public secondary schools.. The multi-stage sample procedure was adopted to select the sample. The research instrument used for the collection of the data was Achievement Test in Oral English (ATOE) which consisted of Oral English questions. The validity of the instrument was ascertained while the test -retest method was used to determine the reliability of the instrument using Pearson Product Moment correlation analysis, a co-efficient of 0.83 was obtained for the instrument and this was considered adequate for the study. The experimental procedure was in stages. These included the training of the research assistants, administration of the pretest, conduct of the treatment and the administration of the posttest. The treatment lasted for six weeks. Data collected were analyzed using descriptive statistics of mean and standard deviation while the eight hypotheses were analyzed using inferential statistics such as t test, ANOVA and analysis of co-variance (ANCOVA). The result showed significant improvement in students’ academic performance after exposing them to audio- visual materials.  It was recommended others that schools and educators should integrate audio-visual materials in language teaching curricula and teachers should receive training and workshops on how to effectively utilize audio-visual materials in the classroom.
