The present invention relates to a courseware using visual auditory simulation technique that incorporates multimedia flash to systematically foster the attention for normal (3 - 6 years chronological) and special children (7 - 12 years chronological); and 2) to ascertain the effectiveness of Visual Audio Simulation Technique in promoting on-task behavior of normal (3 - 6 years chronological) and special children (7 - 12 years chronological). The invention adopts both the quantitative and qualitative approaches by using a visual auditory simulation technique in promoting the on-task behavior of 30 normal and 30 special children. The frequency of on-task behavior before and after the intervention will be recorded.
