Impact of audio-visual materials in the dissemination of knowledge for facilitators in some selected literacy centres in Oshodi/Isolo Local Government Area

Abstract

Today we are living in the era of information and communication technology where a child starts playing on a touch-screen before he learns to crawl. The power of technology has captured the minds of the generation and this influence could be seen in the field of education too. The technology for teaching students in this competitive scenario is the use of Audio-Visual aids. Audio relates to “hearing”, visual is “seeing” and aids are the tools that are used for this purpose. Apart from the use of text-books when the teacher uses audio-visual aids, the topic becomes more clear, effective and easy to understand and thus it lasts forever in the mind of students. Audio- aids can be in the form of recordings, music/sound, songs etc and visual aids can be in the form of power point presentations, video clippings, movie etc or can be the combination of both. This research paper intends to investigate the development of students with the use of audio visual aids with complete virtual learning and their impact. It also compares the use of traditional method with the modern teaching methodology. For this, the impact of audio visual materials in the dissemination of knowledge in some selected literacy centres was studied. The research adopts descriptive research survey with focus on students attending various literacy centres in Oshodi/Isolo Local Government Area and the instrument used for the study was a questionnaire developed to cover the research questions and hypotheses. Fifty respondents were randomly selected from various literacy centres in Oshodi/Isolo Local Government Area of Lagos State for data collection. Data were analyzed using frequency tables and percentages. It can be concluded that as was suggested in the paper that there is a great impact of audio-visual aids in the teaching-learning process in various literacy centres in the state. It also motivates students to attend lectures as they are very curious to see or hear what the facilitator is going to show them in the upcoming class, saves time of copying notes and increasing more communication skills.
