Abstract
The aims of this study were to: 1) investigate the overall efficiency of the instructional pronunciation package, 2) compare the students’ achievement in pronunciation before and after the training, and 3) evaluate the students’ satisfaction with the instructional English pronunciation package in a Computer Assisted Pronunciation Training (CAPT) system. The samples were 30 undergraduate students from two public universities, who had been selected by simple random sampling. The pre-experimental research, a one group pretest and posttest design, was conducted with 12 interventions over 4 weeks on the Microsoft Teams platform. The instruments were as follows: 1) the RP application and the IR tool, 2) a pronunciation performance test consisting of a 30-word list for pre-test and post-test, 3) a questionnaire to survey students’ satisfaction toward the instructional pronunciation package in the CAPT system, and 4) reading texts of the pronunciation practices, which noted the score profiles at the end of each of the 12 interventions. The data was analyzed with SPSS version 20 to determine Mean, Percentage, Standard Deviation, E1/E2, and the t-test. The findings revealed that the instructional pronunciation efficiency had been 89.32/86.80, according to the specified 80/80 criteria, reflecting that it had been efficient. The undergraduate students’ pronunciation skills had also improved given that the mean score of the post-tests was higher than the pre-test with the level of significance at 0.01. The students’ satisfaction with the instructional English pronunciation package in the CAPT system had been strongly positive.
