The Study Effects of Media Development Using Sound-to-Image Technology on the Learning Achievement of Students with Hearing Impairments in Udon Thani Province

Abstract

          This quasi-experimental research aimed to study the effect of media development using sound-to-image technology on the learning achievement of students with hearing impairments in Udon Thani Province. The participants were 50 students with deafness of Mathayom 1 - 3 in Udon Thani School for the Deaf, Mueang District, Udon Thani Province, by purposive random sampling. The experiment tool used was a teaching medium to promote learning achievement using sound-to-picture technology. The index of item objective congruence was 0.98 and the collected data tool was the 5-level rating scale of the learning achievement assessment form for the hearing impaired. The index of item-objective congruence was 0.90. Descriptive statistics were percentage, mean, and standard deviation to describe characteristics such as gender, age, and education. Inferential statistics include the paired sample t-test to compare the average of learning achievement before and after the experiment, the Wilcoxon rank-sum test, and the Shapiro-Wilk test. Statistical significance was set at the 0.05 level.

          The results found that most of the students were 27 males (54%), 23 females (46%), with an average age of 14.2 years. Most of them are studying at the Mathayom 2 level, with 18 students (36%), followed by 17 students studying at the Mathayom 3 level (34%). The learning achievement was found to be both in remembering, understanding application, analysis, evaluation, and creativity after the experiment, which were statistically significant different from before the experiment.
