USE OF MODELLING TECHNIQUE AND SIGN LANGUAGE VDO EXERCISE TO IMPROVE SIGN LANGUAGE VOCABULARY MEMORY OF A STUDENT WITH DEAFNESS AND INTELLECTUAL DISABILITIES

Abstract

The purpose of this research was to develop the memory ability of a student with deafness and intellectual disabilities by using modelling technique with sign language VDO exercises. The case study, female aged 11 years with an Intelligence Quotient level of 36, was selected based on a purposive sampling. The tools used in the research were 1) a pre- and post-test, 2) four individualized implementation plans, namely: Plan 1: My Name; Plan 2: My Favorite Snack; Plan 3: My Father; and Plan 4: My Mother. The selected sign language vocabularies were easy and necessary for the daily life of case study in order to create sign language VDO exercise in all four individualized implementation plans. Data were analyzed by using frequencies, percentages, mean and descriptive analysis. The results of research indicated that the case study had increased ability to memorize sign language vocabulary. A pretest mean score was 11.50 and a posttest mean score was 29.75, with a difference of 18.25 point (36.50 %). And the average score in identifying pictures from memorizing sign language vocabulary according to all 4 individualized implementation plans revealed as follows: 1) Plan 1: it was found that a vocabulary memory score of the case study at a pretest was 40 % and a score at a posttest was 80 %, which was at a very good level. 2) Plan 2: was found that a vocabulary memory score of the case study at a pretest was 50 % and a score at a posttest was 60 %, which was at a good level. 3) Plan 3: it was found that a vocabulary memory score of the case study at a pretest was 20 % and a score at a posttest was 70 %, which was at a good level. 4) Plan 4: it was found that a vocabulary memory score of the case study at a pretest was 20 % and a score at a posttest was 60 %, which was at a good level.
