The purpose of this study was to examine the use of audio visual materials in the teaching and learning of geography. The research design adopted was the quasi-experimental. The objectives were to assess the extent to which the comprehension of students taught geography using audio-visual aids differ from those taught using chalk and talk teaching process; the extent to which demonstrations of students taught geography using audio-visual aids differ from those taught using chalk and talk teaching process and the difference in ease of teaching with which teachers who teach geography using audio-visual aids have from those who teach using chalk and talk. Questionnaires were administered to 12 teachers and 100 form 3 students. A teacher made performance test was used to collect data from the students for the pretest and posttest. T-test analysis was used to test the statistical significance between the post-test scores of experimental and control groups. The results showed that there is a significant higher level of comprehension and demonstrations of the students when taught using audio-visuals compared to when taught using chalk and talk and teachers who teach using audio-visual aids find it easier to teach compared to those who teach using chalk and talk. It is highly recommended that there should be routine checks and maintenance of the technological devices available in secondary schools in Cameroon. Teachers should use various audio visual materials to meet different needs of the learners and seminars on the effective integration of some of these educational technologies should be organized at the beginning of each academic year.
