Practical Test Result of Visuanlized Exercises of Number Symbol for Children with Autism Spectrum Disorder Aged 5-6 Years Old in Specialized Settings

Abstract

The paper indicated the results of using data visualization to form number symbol (NS) for two children with Autism Spectrum Disorder (ADS). Based on the strength of visual thinking of children with ASD, we have designed a set of symbol exercises from easy to difficult arrangement for pre-schoolers. In addition, exercises are developed in specific and detailed procedures, combining visual and writing instructions to make children easily manipulate and comprehend. After conducting experiment by 02 children with ASD at 5-6 years old, there has been a remarkable improvement in forming number symbol and the concentration to do these exercises. Case 1: The concentration was reported to increase from 12,5% to 50%; The number symbol formation was reported to increase from 22,75% to 71,87%. Case 2: The Concentration was reported to increase from 0% to 37,5%; Number symbol was reported to increase from 36% to 64%. Thus, the data visualization exercises have showed many positive effects for the process of forming children's number symbol.
