A Study On Audio Based Tactile Model (ABT) In Learning Human Organ System Among Children With Visual Impairment

Abstract

A study was conducted among 30 secondary level students with visual impairments in four special schools inChennai to facilitate learning science concepts. Traditionally, Science was considered a complex subject, and it is more difficult for the students who have difficulties in vision.The aim of this study was to develop an adaptive teaching-learning material, namely the Audio-Based Tactile (ABT) Model, to teachthe Human organ System.Purposive sampling technique was used to identify and assign the participants. The Audio Based Tactile Material was prepared in both English and Tamil language with the detail of a human organ (Digestive System). The students were allowed to learn it individually for a period of 2 months. A tool was developed and standardized to conduct pre and post test scores, and Quasi-Experimental method was followed. The t-test results for pre and post test evaluation were significant at 0.05 level,revealing that the ABT Model was effective in learning Human Organ System (Digestive System) among students with visual impairments. The Audio Based Tactile teaching materialpositively impacts learning achievements with high enjoyment and curiosity.
