Abstract

    The special educational needs for visually impaired children are tactile and written learning. This study aimed at the preparation of rubber sheets for making convex drawing rubber boards, studying its effectiveness and satisfaction for children with a visual impairment. This quasi-experimental research study used a purposive sample group, consist of 31 children with visual impairments in grades 5-6 and teachers in Bangkok blind schools. The researcher administered an evaluation suitability form and a satisfaction form with a mean suitability of 0.95 and 0.97 respectively. The data were collected and analyzed using the descriptive statistics of frequency distribution, percentage and mean and the researcher calculated process efficiency and results. The results showed that rubber sheets can be prepared for convex drawing boards with physical characteristics comparable to commercial polymer rubber sheets. When the rubber sheet is assembled into a set of drawing rubber boards and tested for efficiency, it was found that the efficiency is higher than the set criteria. In addition, the study of opinions of children with visual impairments and teachers on the use of convex rubber drawing boards found that they were satisfied at the highest level, both individually and overall. For this reason, it can be concluded that the drawing rubber board is suitable for drawing convex images, which can help to promote and develop learning which will be beneficial to the learning achievement of children with visual impairments.
