Development of the “r” pronunciation skill training Exercise for Thai language students at Roi Et Rajabhat University

Abstract

This research article aimed to: (1) develop pronunciation skill training exercises for the Thai consonant “r” for Thai language students with an efficiency criterion of 80/80; (2) examine the learning achievement of Thai language students using the “r” pronunciation skill training exercises by comparing their pre-test and post-test results; and (3) study the learning management competencies of Thai language students through the use of the “r” pronunciation skill training exercises in instructional management within educational institutions. This study employed a Research and Development (R&D) approach and incorporated a quasi-experimental research design. The sample consisted of 16 first-year Thai language students enrolled in the second semester of the 2024 academic year, selected through purposive sampling. The research instruments included five sets of “r” pronunciation skill training exercises, one achievement test on “r” pronunciation, and five lesson plans on the art of “r” pronunciation, each lasting two hours. The statistics used for data analysis were mean and standard deviation. The results revealed that: (1) the “r” pronunciation skill training exercises for Thai language students achieved a process efficiency of 86.70 and an outcome efficiency of 96.25 (E1/E2 = 86.70/96.25), which met the established criterion; (2) a comparison of students’ “r” pronunciation skills before and after using the training exercises indicated that the mean post-test score was significantly higher than the mean pre-test score at the .05 level of statistical significance (Sig. = .000 < .05); and (3) overall, the students demonstrated learning management competency at a very high level.
