This study was conducted (i) to develop computer-assisted musical pronunciation course ware for teaching English word stress, sentence stress and intonation; (ii) to enhance learners’ abilities in proper English word stress, sentence stress and intonationpatterns by using computer-assisted musical pronunciation courseware; and (iii) to investigate learners’ attitudes toward computer-assisted musical pronunciation
courseware. To achieve the first purpose, the Computer-Assisted Musical Pronunciation
was constructed. It consisted of the pre-pronunciation test, 10 lessons about English suprasegmentals, and the post pronunciation test. The lessons in the computer- assisted musical pronunciation courseware consisted of content about English
suprasegmentals, exercises, and songs. The contents were studied and selected. Then,
the words and sentences were selected by 3 teachers who teach Business English. After
that, the contents were checked for content validity by 3 experts. The music and songs
were written and composed based on the content of each lesson. The next step was conducting trials of the courseware with the one-to-one testing and small group testing. The courseware was then used with the sample group. The sample took the pronunciation test. The students then registered and logged in to learn the English suprasegmentals lessons in their own time. The students studied each lesson for one hour. After the students finished all lessons, the questionnaire was sent by e-mail. The efficiency of the CAMP courseware was found to be 83.57/91.33 and the effectiveness index was 0.86. For the second purpose, the pronunciation test constructed by the researcher was used both for pre-test and post-test but each was arranged in different order. The pronunciation test was used to test both students’ perception and production. The perception was tested by listening test with 40 items of 40 points. The students had to listen to the audio sounds on the CAMP course ware, and then they had to choose the suitable answer. The listening test was in a multiple choice format. The students’ production was tested by pronunciation test with 20 items of
40 points. The students were asked to read the words with the suitable stress and read
the sentences with the suitable intonation. The post-pronunciation test mean score was
73.07 higher than the pre-pronunciation test mean score of 41.47.
This difference was found to be significant at the level 0.05 level. For the third purpose, the questionnaire was constructed. There were 30 items which were divided into three parts as follows: 1) Part 1 asked about the students’ demographic data. 2) Part 2 asked about students’ experiential information about their English experience, music experience, and computer experience. 3) Part 3 asked about the students’ attitude toward the CAMP courseware. The questions in this part used Likert’s scale. The students’ attitude toward the CAMP courseware was found to be positive. The students can learn a lot from the CAMP courseware. Their expressed their opinions about the explanation of the content, the sequence, the lyrics and music could help them learn a lot. In addition, they were satisfied with the CAMP courseware. They felt that the lessons made them learn well and they also thought that the exercises helped them to have self-confidence about using English suprasegmentals.
