The Study of Development an Innovative Raised Line Drawing Kit for Students with Visual Impairment

Abstract

The study of development an innovative raised line drawing kit for students with visual impairment aimed to develop an innovative raised line drawing kit for students with visual impairment, an efficiency on using raised line drawing kit for students with visual impairment and study satisfaction of students with visual impairment in using raised line drawing kit to generating tactile graphic. The quasi-Experimental Design; one group posttest Design was use in data collection. Participants of the study were 10 students with visual impairment who study in grade 6 and 1 sighted teacher of Bangkok school for the blind, participants were selected by purposive sampling method. A set of raised line drawing kit consist of 4 items: 1) rubber sheet 2) clip board 3) clear thin plastic sheet and 4) ball point pen. The author found that rubber sheet which made from latex still remain adverse smell of latex. Consequently, another type of rubber sheet was reproduced from polymer. Two type of Rubber sheet was applied to raised line drawing kit and its where try out by others students with visual impairment for preliminary study. We found that both latex rubber sheet and polymer rubber sheet have similar property in generating raised line of tactile graphic, The result of developmental test during producing process also indicated that both type of rubber sheet have similar properties. For another items such as clip board, clear thin plastic sheet and inkless ball point pen size 0.5 mm. are marketable. Both type of innovative raised line drawing kit was apply as learning materials in 11 geometry lessons, one lesson was divided into 2 periods and one period for 60 minutes. The efficiency test E1/E2 was used to indicate an efficiency of using innovative raised line drawing kit as a learning materials, E1/E2 = 70/70 was set for a criteria of efficiency value. Result of the study shown that means of efficiency of process and means of efficiency of outcome of the students higher than 70/70.The satisfaction of using both type of raised line drawing kits was high, the latex type raised line drawing kit M = 3.73 and polymer type raised line drawing kit M = 3.99. Polymer type raised line drawing kit have vivid color that easy detectable by student who have low vision. Moreover, both type of rubber sheets are smoothly drawing in generating tactile graphic. The natural latex type of raised line drawing kit is needed to improve some more property, in the same time, the raised line drawing kit production should be included in the policy on developing quality of teaching students with visual impairment.
