Effectiveness of using an electronic audiobook for the pronunciation of Korean vowels, consonants, and final sounds to improve the pronunciation skills of Thai teachers
Main Article Content
Abstract
This research aims to: 1) develop an electronic audiobook on the pronunciation of Korean vowels, consonants, and final sounds; 2) compare the effectiveness of the electronic audiobook among Thai teachers; and 3) assess the Thai teachers’ satisfaction with the use of the electronic audiobook. The sample group consists of 100 teachers who teach Korean in schools under the Office of the Basic Education Commission (OBEC). The research tools used are: 1) the electronic audiobook; 2) the quality assessment form for the electronic audiobook; 3) the achievement assessment form using the electronic audiobook; and 4) the satisfaction assessment form for learning through the electronic audiobook. Data were analyzed using percentages, means, standard deviations, t-tests, and E1/E2 efficiency measures. The research results are as follows: 1) The quality of the electronic audiobooks, as evaluated by experts, is at a good level, with an average score of 4.47 and a standard deviation of 0.57. The developed electronic audiobook has an E1/E2 efficiency score that meets the criterion of an average of 80%, with scores of 83.34/89.90. 2) the results showed that using an electronic audiobook on the pronunciation of Korean vowels, consonants, and final sounds is effective in improving Korean pronunciation skills as evidenced by the highly significant difference (p = 0.000) between the scores of post-tests of the control group and experimental group using t-test. 3). The evaluation of satisfaction with learning pronunciation skills via the electronic audio-book was at the highest level, with an average score of 4.65 and a standard deviation of 0.34.
